aTwist-Lock connector,the meter automatically senses it and selects the appropriate mode and stan-dardize menus for that type of electrode.Glass pH/ATC,FET pH/ATC electrode,con-ductivity/ATC cell or ATC Probe (with Twist-Lock connector):Connect the electrode to the Twist-Lock input located at the top of the meter.Line up the white arrow and line on the elec-trode’s Twist-Lock connector and push until it locks in place.To disconnect,twist the connector ring in the arrow direction and pull apart.pH,ORP or ISE electrode (with BNC con-nector):Connect the electrode to the BNC input located at the top of the meter.Push in and rotate the electrode’s BNC connec-tor until it locks in place.To disconnect,twist the BNC connector in the opposite direction and pull.Electrode Pair Using a Reference Electrode (with Reference Pin Plug):Connect the indicating electrode to the BNC input.Connect the reference elec-trode to the Reference input.Push the electrode’s tip pin plug into the input toconnect and pull out to disconnect.BNCInputUsing and Storing ElectrodespH ElectrodesProvide moderate stirring for fasterelectrode response.Rinse the electrode between eachmeasurement with a portion of thenext sample or buffer to be measured, or with deionized or distilled water.Keep glass electrodes wet when notbeing used by moistening the cotton in their end covers with electrode fillingsolution and storing them with endcovers on,or by placing in their stor-age vials.Keeping glass electrodes “wet”willimprove their performance.In the lab,store electrodes in electrode filling solu-tion or storage solution (4M KCl).Forelectrodes used in field applications,occasionally leave them in solutions for several hours.Solid-State FET ElectrodeThe model PHH-925 allows use of both standard glass pH/ATC and Solid-State FET (Field Effect Transistor) pH/ATC elec-trodes.The meter can store a calibra-tion for both types of electrodes.Plugthe FET electrode into the Twist-lockinput.Allow the FET about 2 minutes to warm up and stabilize when first con-nected.The FET electrode can bestored dry or in electrode storage solu-tion.If the FET electrode remains con-nected to the meter (and batteries are in the meter),further warm up is notnecessary.Ion Selective ElectrodesAdd proper amount of Ionic StrengthAdjuster (ISA) to all standards andsamples.Provide moderate stirring for fasterelectrode response.Rinse the electrode(s) between eachmeasurement with a portion of thenext sample or standard to be mea-sured,or with deionized or distilledwater.In the lab,follow the instruction sheets for the individual electrode.Store asrecommended.Conductivity CellsRinse the cell between each measure-ment with a portion of the next sample or standard to be measured.Immerse the cell fully into the standard or sample to be measured,lift the cell to allow the solution inside the cell todrain,and immerse the cell again.Repeat three times.Stir briefly and tap the cell against the container bottom to dislodge airbubbles.Clean any deposits from the cell body by rinsing with deionized water andstore dry.E l e c t r o d e P o t e n t i a l ,m V Titrant Volume,mLRedox TitrationConductivity

The digits are larger than typical 1⁄8 DIN panel meters. The iSeriesmeters feature LED displays that can be programmed to change color between GREEN, AMBER,and RED at any setpoint oralarm point. The “CNi8” model is available as an extremely accurate programmable digital panel meter with no outputs or with dual outputs for controlling or alarming functions. Other options include isolated programmable analog output, serial communications, and Ethernet. The user can easily program the CNi8 for any control or alarming requirement from simple on/off to full autotune PID with a choice of form C SPDT relays, solid state relays, DC pulse, and analog (voltage and current) outputs.Fully isolated analog output for retransmission of the process value is available in addition to the control and alarm relays (specify model CNi8A33). The CNi8 covers a broad selection of transducer and transmitter inputs with 2 input models.The universal temperature and process instrument (CNi models) handles 10 common types of thermocouples, multiple RTDs, and several process (DC) voltage and current ranges. This model also features built-in excitation, 24 Vdc @ 25 mA. With its wide choice of signal inputs, this model is an excellent choice for measuring or controlling temperature with a thermocouple, RTD, or 4 to 20 mA transmitter.The strain and process instruments (CNiS models) measure inputs from load cells, pressure transducers, and most any strain gage sensor as well as process voltage and current ranges. The CNiS has built-in 5 or 10 Vdc excitation for bridge transducers, 5 Vdc @ 40 mA or 10 Vdc @ 60 mA (any excitation voltage between 5 and 24 Vdc is available by special order). This CNiS model supports 4- and 6-wire bridge configurations, ratiometric and non-ratiometric measurements. The CNiS features fast and easy “in process” calibration/scaling of the signal inputs to any engineering units. This model also features 10-point linearization which allows the user to linearize the signal input from extremely nonlineartransducers of all kinds.1⁄8 DIN Temperature, Process and Strain PID Controllers Shown smaller than actual size.Ordering Examples: CNi8A22, 1⁄8 DIN temperature/processcontroller with isolated analog output and 2 SSR outputs.
