Polarographic will be abbreviated Polaro in the instrument.Galvanic – This sensor has a grey sensor body and is engraved with the model number 2002.For information about the differences on the two sensor types, see Sensor Type in the System Setup menu section and/or the Principles of Operation section of this manual.If using a ProBOD sensor/cable assembly, there is no need to install a sensor because it has a built in Polarographic dissolved oxygen sensor.Before installing either sensor or connecting the cable to theinstrument, the Sensor Type must be configured for the sensor beinginstalled/connected. Failure to do this may result in damage notLcovered under warranty. The instrument will step you through thissetup the first time it is powered on. See the System Setup menusection of this manual for instructions on configuring the SensorType after the first power on.1)Ensure both the sensor connector and sensor port on the cable are clean anddry.2)Grasp the sensor with one hand and the cable bulkhead in the other.3)Push the sensor into the connector on the cable until it is firmly seated andonly 1 o-ring is visible. Failure to properly seat the sensor may result indamage.4)Twist the sensor clockwise to engage threads and finger tighten. Do NOTuse a tool. This connection is water-tight.For more detailed instructions, please refer to the sensor installation sheet that is included with each sensor.Figure 3 BulkheadSensor5CONNECTING THE CABLEThe Pro20 is designed for field and laboratory use. It is compatible with two different cable options:1) The field rugged cable is available in standard lengths of 1, 4, 10, 20, 30, and 100 meters with special lengths available between 30 and 100 meters. This cable has a built in temperature sensor and includes a port for the dissolved oxygen sensor. 2) The ProBOD is a 1 meter probe/cable assembly with built in Polarographic dissolved oxygen and temperature sensors. It has an AC powered motor for sample stirring and is designed to fit into a 300 ml BOD bottle.To connect the cable, align the keys in the cable connector to the slots in the instrument connector. Push together firmly and then twist the outer ring until itlocks into place (Figure 4). This connection is water-proof.Figure 4, Note the keyed connector. When disconnected, the sensor and cable’s sensor connectors areNOT water-proof. Do not submerge the cable without a sensorinstalled. When disconnected, the cable’s instrument connector andthe connector on the instrument maintain a waterproof, IP-67rating.L6MEMBRANE INSTALLATIONThe dissolved oxygen sensor is shipped with a dry, protective red cap that will need to be removed before using. It is very important to put a new membrane with electrolyte solution on the sensor after removing the red cap.Prepare the membrane solution according to the instructions on the bottle. After mixing, allow the solution to sit for 1 hour. This will help prevent air bubbles from later developing under the membrane. Ensure you are using the correct electrolyte solution for the correct sensor. Galvanic sensors utilize electrolyte with a light blue label and Polarographic sensors utilize electrolyte with a white label. The D issolved Oxygen sensor is supplied with cap membranes specific to the sensor type ordered (Polarographic or Galvanic). 5913 and 5914 membrane kits are for Galvanic sensors and the 5908 and 5909 membrane kits are for Polarographic sensors.Remove and discard or save the red protective cap. Thoroughly rinse the sensor tip with distilled or deionized water. Fill the cap membrane 3⁄4 full of electrolyte solution, then tap the cap with a finger to release any trapped air. Be careful not to touch the membrane portion of the cap. Thread the membrane cap onto the sensor, moderately tight. Do not use a tool. It’s typical for some of the electrolyte solution to spill over. It is best to allow the new cap to remain on a new sensor overnight before trying to calibrate. For detailed instructions on changing a membrane cap, see the Care, Maintenance, and Storage section of this manual. BACKLIGHTOnce the instrument is on, pressing power/backlight key will turn on the display backlight.

To adjust the contrast, press and hold the menu key, then press the up arrow key to darken the contrast or press the down arrow key to lighten the contrast.SENSOR TYPEThe instrument’s Sensor Type must be configured for the sensorLinstalled. Failure to do this may result in damage not coveredunder warranty. If you observe readings very close to 0 orextremely high readings, i.e. 600%, your Sensor Type setting maybe set incorrectly.Sensor Type sets the type of oxygen sensor being used; either Polarographic (black) or Galvanic (grey).Use the up or down arrow keys to highlight Sensor Type, then press enter to open a submenu. Highlight the sensor type corresponding to the sensor installed on the cable and press enter to confirm. The enabled sensor type will have an ‘X’ in the box next to it. Use the down arrow key to highlight the ESC – Exit, then press enter to save changes and to close the sensor submenu.If using a ProBOD sensor/cable assembly, the sensor type should be set to polarographic.The Pro20 has two compatible sensors for use with a field cable:Polarographic – This sensor has a black sensor body and is engraved with the model number 2003. Polarographic will be abbreviated Polaro in the instrument. Galvanic – This sensor has a grey sensor body and is engraved with the model number 2002.In terms of physical configuration, membrane material, and general performance, YSI Professional Series Galvanic dissolved oxygen sensors are exactly like the Professional Series Polarographic sensors. The advantage of using Galvanic sensors is convenience. Galvanic sensors provide for an instant-on sensor without the need for warm-up time but this affects the life of the sensor. Polarographic sensors last longer and have a longer warranty but require a 5-15 minute warm-up time before use or calibration.MEMBRANE TYPEMembrane Type sets the type of membrane used on the dissolved oxygen sensor; either 1.25 PE (Yellow) or 2.0 PE (blue). Use the up or down arrow keys to highlight Membrane Type and press enter to open the membrane submenu.

A Factory Reset will not affectdata saved in the unit’s memory.The following will be set in the Pro20 after performing a factory reset:Defaults Parameter Reset Temperature Units o CDissolved Oxygen Units mg/L and %Pressure Units mmHgDissolved Oxygen Sensor Type Last Setting ConfirmedMembrane Type Last Setting ConfirmedSalinity Compensation Value 0.0 pptDO Local% OffOne Touch Cal OnDisplay Contrast Set to mid rangeAuto Shutoff 30 minutesAuto Stable Off (0.0 % Change and 10 secs)LDS (Last Digit Suppression) OffAudio OnLanguage EnglishDissolved Oxygen Calibration Reset to factory default, 100% forenabled membrane and sensor*Barometer Calibration Reset to factory default**It is recommended to perform a barometer and dissolved oxygen calibrationafter performing a reset.EXITING THE SYSTEM SETUP MENUTo exit the System Setup menu, press the down arrow key until the ESC - Exit box is highlighted, then press enter to return to the run screen.C A L I B R A T I O NTEMPERATUREAll cable assemblies have built-in, temperature sensors. Temperature calibration is not required nor is it available.BAROMETERThe barometer in the Pro20 is calibrated at the factory. The barometer reading must be accurate to ensure accurate % calibrations and D O readings. If your barometer requires an adjustment, use the up or down arrow keys to highlight the barometer box on the run screen, then press enter. Next, use the up or down arrow keys to adjust the barometer reading to the local, true barometric pressure. Continually depress the up or down arrow keys to change the barometer value more rapidly. Press enter to confirm and save the barometer adjustment.Do not use a barometer value that is corrected to sea level.Laboratory barometer readings are usually “true” (uncorrected)Lvalues of air pressure and can be used “as is” for barometercalibration. Weather service readings are usually not “true”, i.e.,they are corrected to sea level, and therefore cannot be used untilthey are “uncorrected”. An approximate formula for this“uncorrection” is:True BP = [Corrected BP] – [2.5 * (Local Altitude in ft above sea level/100)]Although the barometer range is 400.0 to 999.9 mmHg, you will beLunable to adjust the value across the entire range. The barometer isvery accurate and the instrument will not allow you to adjust thevalue drastically beyond what it is measuring during calibration.DISSOLVED OXYGENThe Pro20 can be easily calibrated with the press of one key by enabling One Touch Cal in the System Setup menu and following the One Touch Calibration procedure.Ensure the barometer is reading accurately before performing a One Touch Calibration, DO %, or DO Local% calibration. These calibration procedures use the barometer reading during calibration. If the barometer reading is erroneous during a calibration, your dissolved oxygen values will be inaccurate.It is not necessary to calibrate in both % and mg/L or ppm.LCalibrating in % will simultaneously calibrate mg/L and ppm andvice versa. YSI recommends calibrating dissolved oxygen in % forboth ease and accuracy.ONE TOUCH CALIBRATIONPerform this calibration procedure when One Touch Cal is enabled in the System Setup menu.If using a field cable, install the sensor guard onto the probe. Moisten the sponge in the grey calibration/storage sleeve with a small amount of water and install it over the sensor guard. The sleeve should be moist, but should not have excess water that could cause water droplets to get on the membrane. The storage sleeve ensures venting to the atmosphere.If using the ProBOD sensor/cable assembly, place the probe in 300 ml BOD bottle with a small amount of water (1/8 inch or 0.3 cm). The dissolved oxygen and temperature sensors should not be immersed in water.If the calibration/storage sleeve is not available, substitute with a chamber of 100% relative humidity, vented to the atmosphere (not completely sealed).Power the instrument on and wait approximately 5 to 15 minutes for the storage chamber to become completely saturated and to allow the sensor to stabilize if using a Polarographic sensor. If using a Galvanic sensor, wait approximately 5 to 10 minutes for the chamber to become completely saturated. Auto Shutoff time should be disabled or set to at least 20 minutes, see System Setup menu for more information on adjusting the Auto Shutoff.。
