3. PreparationInserting the batteries (included)1. If the electrode cable is woundaround the the cable winder,unwind it.2. Use a Phillips screwdriver toremove the two screws holdingthe battery cover. See Figure B.3. Lift meter stand to exposebattery cover.4. Remove battery cover.5. Insert batteries. Make surepolarity is correct.6. Replace the battery cover intoits original position using thetwo screws removed earlier.Place the meter stand in thefolded position.BNCconnectorphonojackMeterstandThese 2 screws hold thebattery cover in place.Connecting the electrode and thetemperature probeMeter accepts any pH, ORP or ISEelectrode with a BNC connector.The temperature sensor connects tothe meter using a phono jack for thetemperature probe.Connecting the pH electrode. Hook upthe electrode to the male BNC jack on thetop of the meter as shown in Figure C.Make sure connector is clean and dry.CTemperature probe. The temperatureprobe uses a phono jack to connect with the socket on the meter. Insert thejack into socket as shown in Figure C. If you are using an OAKTON “All-In-One”electrode, the temperature sensor is built in to the pH electrode and the oneelectrode cable will have both a BNC connector for pH and a phono jack fortemperature.BAttaching the electrode holder to the meter1. Place the electrode holder with the flangefacing the slot on the meter.2. Gently slide the flange of the holder in the slot(See Figure D at left). Make sure holder is fixedproperly into the slot.You can attach the electrode holder in differentpositions, as shown in Figure E. This flexibilityfacilitates one-hand operation.Inserting electrode into the electrode holderThe meter includes one electrode holder. Makesure to insert the electrode into the holdergently, or the electrode may break.1. Insert the electrode into the opening of theholder until the top housing of the electrodetouches the top of the holder as shown inFigure E. Do not force the electrode into theopening.NOTE: If you substitute the electrode, youneed to use an electrode with a 12 mmdiameter. Otherwise, the electrode maynot fit properly.FDConnecting the AC adapter (notincluded; order on page 21)1. Insert the AC jack as shown inFigure F at right.2. Switch off the meter before pluggingthe adapter into the power source.This safety precaution protects thesoftware in your meter.3. Switch on the meter power.EPage 6Page 7
4. pH CalibrationThis instrument is capable of up to 3-point calibration to ensure accuracyacross the entire range of the meter. You can perform 1-, 2,-, or 3-pointcalibration with standard pH buffers 4.01, 7.00 and 10.01.We recommend that you perform at least a 2-point calibration using standardbuffers that bracket (one above and one below) the expected sample range.You can also perform a 1-point calibration, but make sure that the buffer valueis close to the sample value you are measuring.All new calibrations will over-ride existing stored calibration data.NOTE: Do not reuse solutions after calibration. Contaminants in the solutioncan affect the calibration, and eventually the accuracy of themeasurements.NOTE: Be sure to remove the protective rubber cap of the electrode beforemeasurement.1. Select pH mode (automatic when meter isswitched on). See Figure G.MEASREADYpH2. Rinse the electrode thoroughly withdeionized water or a rinse solution.°CDo not wipe the electrode; this causes aATCbuild-up of electrostatic charge on thepHglass surface.G3. Dip the electrode into the sample. Theglass bulb of the electrode must beCALcompletely immersed into the sample.pHStir the electrode gently to create ahomogeneous sample.pH4. Press CAL/MEAS. The display will showATCCAL—see Figure H. The primary displaypHwill show the measured reading while thesmaller secondary display will indicate theHpH standard buffer solution.NOTE: If using a buffer other than pH 7, press the ▼ or ▲ keys to scroll upor down until the secondary display value is the same as your pHbuffer value.5. Wait for the measured pH value to stabilize. The READY indicator willdisplay when the reading stabilizes.6. Press CON to confirm calibration. Aconfirming indicator flashes for one secondCAL CONand disappears. See Figure I. The meter is READYpHnow calibrated at the buffer indicated in theprimary display.pHThe secondary display automatically scrollsATCpHto the next buffer calibration option. SeeFIgure I . If you are performing a 1-pointIcalibration, go to step 8.NOTE: The electrode and buffer icon blinkCAL CONand the ERR annunciator lights uppHif the selected buffer value is notwithin ±0.50 pH from thepHmeasured pH value. TheseATCindicators also flash if the bufferpHused is not the same as the buffervalue on the secondary display.J7. Press the ▼ or ▲ key to select the second buffer value you want tocalibrate. The buffer values are shown on the secondary display (pH 4.01,7.00, and 10.01). See Figure J.8. Follow steps 2 through 6 for additional calibration points (up to 3 values).Do not press CAL/MEAS until all calibration is completed.9. Press CAL/MEAS to return to measurement mode.Page 8Page 9
