Maintenance 7.K. Specifications 8.A. GENERAL DESCRIPTIONThe stainless steel probe provides relative humidity as well astemperature out puts. A thin film polymer capacitor senses relative humidity, while temperature is monitored by a 1000 Ohm platinum RTD. The sensors are protected by a stainless steel filter cap easily removed for cleaning. The probe is connected to an electronicsenclosure with a 40 inch (1m) Teflon cable. The enclosure contains the calibration trimmers, signal and power connections via twoterminal blocks. The probe is available in two configurations, as a2.5” (64 mm) probe with a wall mounting clip, and as an 8.5” (216mm) probe with an adjustable duct flange.B. UNPACKINGVerify that the following parts have been received.1.Remove probe with cable and electronics enclosure.2.Instruction manual.3.Wall mounting clip [for 2.5” (64 mm) probe].4. 2 piece duct flange, with o-ring, (3) screws, and a gasket.[for 8.5” (216 mm) probe]C. THEORY OF OPERATIONA 4 to 20 milliamp loop is a series current loop in which atransmitter will vary the current flow depending upon the parameter being measured (Relative Humidity or Temperature). Advantages ofa current output over a voltage output is that is less susceptible tonoise interference and allows the connection of more than one meter or recorder to the loop as long as the maximum resistance is notexceeded.The typical current loop will consist of a power supply, transmitter, and a meter to measure the current flow. The loop resistance is the sum of the impedance of the meter(s) and the lead wire. Themaximum allowable loop impedance of the probe is found by the Formula:Rmax = (power supply voltage-7 volts) /.02 ampsExample: when using a 24 VDC power supply:Rmax= (24-7) /.02=850 ohms (for total wire length to andfrom the transmitter).AWG WIRE SIZE RESISTANCE PER 1000 FEETIf the meter or recorder being used accepts only voltage, convert the current to voltage by installing a 250 ohm resistor across the input terminals of the recorder to obtain a 1 to 5 volts input.D. TERMINAL CONNECTIONS AND TRIM POTSE. WIRING EXAMPLESTYPICAL CURRENT HOOKUP Wires R1 and R2 can be combined into one single wire with a jumper at pins (4) and (2). This will result in 3 wires instead of 4. TRIMPOTS TYPE A. RH GAIN B. RH ZERO C. RH OFFSET D. TEMP GAIN E. TEMP ZEROPROBE INSTALLATIONF. MOUNTINGA.DUCT MOUNTINGSTEPS1.Slide flange holder onto probe with countersinkhole facing front of probe as shown.2.Position o-ring on probe at desired position (for depth intoduct).3.Slide duct flange onto probe as shown.4.Fasten with (3) 6/32 screws and tighten evenly until secure.5.Position gasket between duct flange and duct wall and fastenassembly to duct with (4) #6 sheet metal screws (notincluded).6.Loosening the 6/32 screws allows for repositioning orremoval of the probe without having to remove the ductflange from the wall.The d uct wall requires a 11/16” (.684” or 17.5 mm) hole forprobe, with (4) mounting holes (for #6 sheet metal screws)evenly spaced on a 2.0” (51 mm) circle. Use duct flange astemplate.B.WALL MOUNTING1.Fasten metal clip to wall.2.Snap probe into clip.G. RH AND TEMPERATURE CALCULATIONS1.Maximum current loop impedance for RH or temperature.Rmax = (V supply – 7 volts) /.02 amps2.RH current output (i = current output in milliamperes)3.Temperature current output.oC = (i-4) x 220/16) – 40 iC = (oC + 40) x (16/220) + 4oF = (i-4) x (396/16) – 40 iF = (oF + 40) x (16/396) + 4The upper limit of the humidity measurement range decreases based on temperature. The humidity measurement limit decreases as follows:2.20% per °C from 95 to 120°C (1.11% per °F from 203 to 248°F)1.00% per °C from 120 to 140°C (0.56% per °F from 248 to 284°F) 0.50% per °C from 140 to 160°C (0.28% per °F from 284 to 320°F) 0.25% per °C from 160 to 180°C (0.14% per °F from 320 to 356°F)For example, at 120°C the upper humidity limit decreases to about 45% ((120-95)(2.20%) = 55% decrease which is 45%), at 180°C it is reduced to about 10%.To calculate the RH accuracy, we’ll use the accuracy specs given in the specifications section:+/-2%RH at 25°C and -40° to 150°C at 0.05 % RH/°C.To clarify lets take an example,RH accuracy at 120°C,=+/- (2% + (120-25)0.05%) = +/- (2% + 4.75%)=+/-6.75%So the accuracy at 120°C is +/- 6.75% and the upper humidity measurement limit is 45% RH.H. RH CALIBRATIONRefer to Section D for the location of trim pots A and B.Note: The HX92-CAL Relative Humidity Calibration Kit is for providing the “low” and “high” RH environments for this procedure. The salt solutions in this kit are prepared according to ASTM standard E104-85 to provide 11.3% and 75.3% relative humidity environments. The containers provided in the kit are designed to fit with these instruments.1.Turn the span (trim pot A) all the way up (clockwise).2.Turn the zero (trim pot B) all the way down (counter-clockwise).3.Place the sensor in the low (11.3%) RH environment. Allowat least one hour for stabilization or until the output stopschanging.4.Verify the output is 4 +/-.02 mA. If it is not, return the unitto Omega for evaluation and repair.5.Adjust the zero (trim pot B) to the point where it just starts tocause a change in the output.6.Place the sensor in the high (75.3%) RH environment. Allowat least one hour for stabilization or until the output stopschanging.7.Adjust the span (trim pot A) so the output is equivalent tothe difference between low and high RH environments.Example: 75.3%-11.3% = 64% which is equivalent to 14.24mA.8.Adjust the sensor in the low RH environment and allow atleast one hour for stabilization or until the output stopschanging. Verify the output is equivalent to the low RHenvironment. Example: 11.3% is equivalent to 5.81 mA.I. TEMPERATURE CALIBRATIONTemperature is factory calibrated only, and does not requireany further calibrations.J. MAINTENANCEIf the probe is operated in a dusty environment, theprotective sensor filter, if clogged, may be removed for cleaning.Unscrew filter and gently blow compressed air through screen.If necessary, use a soft brush to remove lint from sensors.If the sensors are subjected to 100% condensation, they must bedried to obtain correct readings. There is no permanentcalibration shift, nor is recalibration necessary if 100%condensation occurs.The instrument should not be exposed to highConcentrations of ammonia or alcohol vapors. However,any environment that is breathable under normal HVACapplications should not affect the sensors. To maintain originalspecifications, it is generally recommended that the RH sensorbe recalibrated on an annual basis depending upon operatingconditions. The temperature sensor does not require calibration.K.

Turn the meter over and use your thumbs or a coin to turn the battery compartment cover (Fig. 1, Callout F) clockwise 30 degrees, in the direction marked OPEN .2. Pull and discard the tab under the pre-installed battery.3. Replace the battery compartment cover and turn it counterclockwise 30 degrees until it snaps shut.Complete Setup by carefully removing the plastic film protecting the LCD.OPERATING INSTRUCTIONSTo power on the HHF-312,press the red button. The LCD will illuminate with the backlight on and show all possible display indications for 2 seconds. The unit will then automatically enter the measurement mode in which it was operating when it powered off. The backlight will turn off after 15 seconds if nofront-panel button is pressed during that period. Pressing any button begins another 15 seconds of backlight.To power off the HHF-312,press and hold thebutton for at least 2 seconds.To change measurement mode, start by pressing the MODE button. This will cause the icon of the current mode to begin flashing on the top line. Then press the SET button once or twice,until the icon of the mode you want begins flashing on the top line.The figure below shows the three measurement modes in their sequence of selection using the SET button.6When the icon of the mode you want appears, flashing, on the top line, press the MODE button once to stop it from flashing. Doing this will cause one or more measurement unit icons below to begin flashing. Press the MODE button again to stop those icons from flashing. This causes the meter to enter real-time measurement mode for the chosen parameter (air/wind speed, RH or barometric pressure).To hold any pair of measurements(“freeze” the readouts), briefly press (but do not hold) the button (which has HOLD stenciled above it). To release the hold and resume displaying real-time values, briefly press the button again. This function is very useful for making measurements in low light or when the source of air or wind is above your head, below your knees, or around a corner. You can make a measurement, hold it, and then read the display up to 5 minutes later after positioning the LCD at eye level.Why do you have only 5 minutes? To extend battery life, the HHF-312automatically powers itself off following any 5-minute period in which no front-panel button is pressed. MEASURING AIR/WIND SPEED AND TEMPERATURESTo make an air/wind speed measurement, unsnap the vane and sensor protection cap (Fig. 1, Callout A) and let it hang from the unit by the wrist strap. Turn the vane at the top of the unit perpendicular to the source of air or wind. It makes no difference whether the front of back of the vane faces the flow. The measured air/wind speed value will appear on the upper readout. Allow a few seconds for the reading to stabilize.The HHF-312’s factory default air/wind speed measurement unit is feet/minute (ft/m). To change the air speed unit, begin by pressing the UNIT button. This will cause ft/m to begin flashing on the right side of the upper readout (Fig. 2, Callout E). Then, within 15 seconds (before the backlight extinguishes), press the SET7button. This will change the flashing ft/m term to mph, also flashing. Press the SET button again and mph will turn to knots. Press it again to change knots to m/s.Press the SET button as many times asnecessary until the air/wind speed unityou prefer appears, flashing, at theright of the upper readout. To save thisunit, press the UNIT button. The figureat right shows the five availableair/wind speed units in their selectionsequence.When you press the UNIT button tosave your preferred air/wind speed unit, °F—the HHF-312 factory default temperature measurement unit—will begin flashing in the lower right corner of the LCD. To keep °F as the temperature measurement unit, begin by pressing the UNIT button. This will cause °F to stop flashing and the meter to resume displaying real-time air/wind speed and temperature measurements. To change the temperature unit to °C, press the SET button, followed by the UNIT button to save the selection. The HHF-312will “remember” the air/wind speed and temperature units (as well as its operating mode and other selected units and parameters) in use each time it powers off and will resume operating in that mode and with those units upon restart. So if you always use ft/m and °F for air/wind speed and temperature measurements, you need not perform any of the above steps. And if you always use the same air/wind speed and temperature units (other than ft/m and °F), you need only perform the above procedure once. Unlike many instruments, changing the battery does not reset all units to their factory default.As mentioned earlier, the HHF-312automatically begins measuring and displaying ambient temperature upon startup. To display other temperatures whose calculation includes the8effect of wind speed or humidity(Wind Chill Index, or Wet Bulb and Dew Point temperatures, respectively), begin by pressing the MODE button with the meter operating in air/wind speed mode (with VEL appearing on the top line of the LCD). This will cause VEL to begin flashing. Then press the MODE button again. On meters that have come fresh from the factory, this will cause the three terms WCI, DEW and WET to appear, flashing, above the lower readout (Fig. 2, Callout J). Within 15 seconds (before the backlight turns off), press the SET button as many times as necessary until the temperature you want appears by itself, flashing, above the lower readout. Note that the temperature below changes with each press of the SET button. To save the temperature you want, press the MODE button while its abbreviated term (WCI, DEW or WET) is flashing.As with air/wind speed units, the type of temperature you select and save becomes the display default until you change it. When operating in Wind Chill Index mode, make sure the vane is perpendicular to the wind direction.DISPLAYING MIN/MAX/AVG AIRAND WIND SPEEDSThe HHF-312keeps track of the maximum and minimum (fastest and slowest) and average air speed values recorded over a measurement “session”—the period of time during which you measure speeds at multiple locations and/or speeds of multiple devices. The session begins when you power on the HHF-312;it typically ends 5 minutes after you finish making measurements with the activation of the APO function.The value of being able to quickly determine, for example, the fastest and slowest fans of a group should be obvious.To display the maximum, minimum or average air/wind speed during a measurement session, press the DISP button as many times as necessary until the label of the desired value (Max, Min9or Avg) appears above the upperreadout (Fig. 2, Callout D). The figureat right shows the three availablesession parameters in their selectionsequence relative to real-timemeasurement mode.MEASURING RELATIVEHUMIDITY (RH)To enter RH mode, press the SETbutton with VEL flashing on the top line of the LCD. This will change the flashing term to RH. To stop RH from flashing, press the MODE button.The HHF-312will now display real-time RH values on the upper readout and the current Wind Chill Index or Dew Point or Wet Bulb temperature on the lower readout. To change the unit of temperature measurement to or from °F or °C, press the SET button, followed by the UNIT button to save the selection. To leave the unit unchanged, press the UNIT button. MEASURING BAROMETRIC PRESSURETo enter barometric pressure mode, press the SET button with RH flashing on the top line of the LCD. This will change the flashing term to BP. To stop BP from flashing, press the MODE button. You can now enter your preference for using the metric or Imperial unit for barometric pressure—the kilopascal (kPa) or millibar (mBAR), respectively. To change kPa to mBAR, begin by pressing the UNIT button. This will cause kPa to begin flashing between the upper and lower readouts (Fig. 2, Callout F). Then press the SET button, followed by the UNIT button to save the selection. Saving the selected barometric pressure unit will cause the default temperature unit at the right of the lower readout to begin flashing. To change the unit, press the SET button, followed by the UNIT button to save the selection. To leave the unit unchanged, press the UNIT button.10STORING AND RECALLING RECORDSThe HHF-312can store up to 20 pairs of the measurements shown on the upper and lower readouts for later recall in chronological order (the order in which they were stored).To store the pair of readings currently on-screen, press the REC button. The readings will be stored at the location indicated by the memory counter (Fig. 2, Callout M) above the memory pointer JOB(Callout L). Note that each press of the REC button increments the memory counter by 1. The HHF-312’s memory is nonvolatile, so stored pairs of readings (collectively called a Record) are retained when the meter powers off, and also after the battery is changed.To recall one or more readings, make sure the meter is operating in one of the three real-time measurement modes (air/wind speed, RH or barometric pressure), with no terms flashing on screen. Then press the RCL/DEL button once. This will replace the term JOB by the memory recall mode indicator Rec(Fig. 2, Callout N) above. Both readouts will switch to displaying the oldest record saved (the pair of readings in memory location 01).To display the next-newest record, press the SET button. Continue pressing the SET button to sequentially display all stored records in the order in which they were saved. Pressing the SET button with the newest record on-screen resets the memory counter to 01. To exit memory recall mode, briefly press (but do not hold) the RCL/DEL button. This will replace the term Rec above the storage location number by the term JOB below it.When the HHF-312’s20-record memory is full, pressing the REC button will not store the current pair of readings—in other words, the memory is not over-writing. To store readings with a full memory, you must delete one or more records manually.11To delete an individual record, first make sure the meter is operating in one of the three real-time measurement modes. Then,1. Press the RCL/DEL button to enter memory recall mode, with Rec replacing JOB at the lower left of the LCD.2. Press the SET button repeatedly until the record to be deleted is on-screen, with its memory location number shown below Rec.3. Briefly press (but do not hold) the REC button to delete the record. This will change Rec to JOB(indicating exit from memory recall mode) and change the readouts to the next-newest pair of stored readings. If no newer readings have been stored, the readouts will switch to the next-oldest pair of readings.To bulk-erase the memory (delete all records), press and hold the REC button for at least 2 seconds with the meter operating in one of its three real-time measurement modes. This will reset the memory counter to 01.USING AND CALIBRATING THE COMPASSThe HHF-312is equipped with a magnetometer (electronic compass) capable of displaying direction within 45 degrees using the standard terms N, NE, E, SE, S, SW, W and NW. Bearings are simultaneously shown in two places: in the upper left corner of the LCD (Fig. 2, Callout Q), and below it at the end of an arrow pointing in that direction (Callout P).To provide accurate readings, the compass should be calibrated after each battery replacement. To begin the calibration process, take the meter outdoors to minimize the effects of indoor electromagnetic interference (EMI). Then:1. Use the MODE and SET buttons to place the meter in air/wind speed measurement mode, with VEL visible but not flashing on the top line of the LCD.122. Press and hold the RCL/DEL button until OH appears on the upper readout and OL appears on the lower readout.3. Holding the meter facing up in front of you, rotate your body through three full 360° turns.4. Press and hold the RCL/DEL button until OH and OL are replaced by real-time air/wind speed and temperature readings on the upper and lower readouts.

Observe polarity.2. Set the DMM to the 200mV range.3. Rotate counter clockwise to remove the protective metal cap.4. Set the power switch to the desired %RH or °F range.5. If the DMM display is over-range. Set the DMM to the 2V range.6. Read the DMM display. (10mV/°F, 10mV/%RH)7. Cover sensor head to extend sensor life when not in use.SPECIAL CONSIDERATIONS•Before a reliable measurement can be made, the measuring hygrometer and medium to be measured must be in temperature and humidity eguilibrium.•Temperature measurement errorsDue to too short measurement time, sunshine during the measurement, heating, cold outer walls, air draft (e.g. fans), radiating hand and / or body heat etc.•Humidity measurement errorsDue to steam, water splashes, dripping water or condensation (not water condensate) on the sensor etc. However, repeatability and long-term stability are not impaired by this.•ContaminationBy dust in the air or measurements in powdery substances. This can be largely avoided by using a corresponding filter. The filter must be cleaned or replaced periodically depending upon the degree of contamination of the measuring site.OPERATOR MAINTENANCEBattery ReplacementPower is supplied by four 1.5V (AAA size) batteries. The "LOW BATT" red LED lighted when replacement is needed. To replace the batteries, remove the screw from the back of the meter and lift off the battery cover.
