Instruction Manual PC 10 1. INTR ODUCTION Thank you for selecting the Waterproof PC 10 portable meter. The meter is a microprocessorbased instrument that measures pH, conductivity, and temperature with just one probe. This meter has many user-friendly features – all of which are completely accessible through the water-resistant membrane keypad. Your meter includes 4 “AAA” batteries and a combination pH / conductivity / temperature probe with 3-meter submersible cable.
Instruction Manual PC 10 2. D ISPLAY AND K EYPAD FU NCTION S 2.1. Display The LCD has a primary and secondary display. • The primary display shows the measured pH or conductivity (µS or mS) reading. • The secondary display shows the temperature in °C. The display also shows error messages, keypad functions and program functions. See Figure 2.
Instruction Manual 2.2. PC 10 Keypad The large membrane keypad makes the instrument easy to use. Each button, when pressed, has a corresponding graphic indicator on the LCD. See Figure 3. Key Function ON/OFF Powers on and shuts off the meter. The meter powers on in the mode it was shut off in. For example, if you shut the meter off in Conductivity measurement mode, the meter will be in Conductivity measurement mode when you switch the meter on. HOLD Freezes the measured reading.
Instruction Manual PC 10 3. PR EPARATION 3.1 Inserting the Batteries The meter is packaged with 4 “AAA” alkaline batteries required for operation. To insert the batteries into the meter, follow the procedure outlined below. 1. Use a Philips screwdriver to remove the two screws holding the battery cover. See Figure 6 below. 2. Remove battery cover. 3. Insert batteries. Follow the diagram inside the cover for correct polarity. 4.
Instruction Manual 3.2 PC 10 Connecting the Probe The Waterproof PC 10 meter uses a special combination pH / Conductivity / Temperature probe. The probe cable has a notched 6-pin connector to attach the probe to the meter. NOTE: Do not substitute other probes or electrodes. For replacement probe, see the “Accessories” section, page 21-23. NOTE: Keep connector dry and clean. Do not touch connector with soiled hands. To connect the pH / Conductivity / Temperature probe: 1.
Instruction Manual PC 10 4. CA LIBRATION 4.1. Important Information on Meter Calibration When you recalibrate your meter, old pH and conductivity calibration data are replaced on a point by point basis. For example, if you previously calibrated your meter at pH 4.0, 7.0, and 10.0, and you recalibrate at pH 7.0, the meter retains the old calibration data at pH 4.0 and pH 10.0.
Instruction Manual 4.2. PC 10 Preparing the Meter for Calibration The pH/conductivity/temperature probe included with this meter is designed for use with this meter only. Do not substitute other types of probes or electrodes. For a replacement probe, see the “Accessories” section, page 21. Be sure to remove the protective cap of the pH probe before calibration or measurement. Always immerse the probe beyond the electrode band.
Instruction Manual 4.3. PC 10 Temperature Calibration The built-in temperature sensor included in the probe is factory calibrated. Calibrate your sensor only if you suspect temperature errors may have occurred over a long period of time or if you have a replacement probe. 1. Turn the meter on. Press MODE to select pH Measurement mode. 2. Press the CAL/MEAS Figure 7: Enter pH Calibration mode key to enter pH calibration mode. The CAL indicator will appear above the primary display.
Instruction Manual 6. PC 10 Press the ENTER key to confirm temperature calibration. The CON indicator will flash to confirm calibration. See Figure 13. NOTES To exit from Temperature Calibration mode without confirming calibration, DO NOT press ENTER in step 6. Press CAL/MEAS instead. Temperature calibration is restricted to ±5°C from Figure 10: CONFIRM temperature calibration the initial value displayed during calibration (shown in the secondary display).
Instruction Manual 4.4. PC 10 pH Calibration This instrument is capable of up to 3-point pH calibration to ensure accuracy across the entire pH range of the meter. You can perform 1, 2, or 3 point calibration with standard pH buffers of 4.01, 7.00 and 10.00. We recommend that you perform at least 2-point calibration using standard buffers that covers the expected sample range. You can also perform a 1-point calibration, but make sure that the buffer value is close to the sample value you are measuring.
Instruction Manual 6. PC 10 After the reading has stabilized and the READY indicator is displayed, press ENTER to confirm calibration. A confirming indicator (CON) flashes and disappears. The meter is now calibrated to the buffer indicated in the secondary display. See Figure 13. The secondary display automatically scrolls to the next buffer calibration option. If you are performing multi-point calibration, go to Figure 13: CONFIRM calibration point step 7.
Instruction Manual 4.5. PC 10 Conductivity Calibration The Important Information on Conductivity Calibration Your meter has four measuring ranges. You can calibrate one point in each of the measuring ranges (up to four points). If you are measuring values in more than one range, make sure to calibrate each of the ranges you are measuring. The following table lists the corresponding conductivity range.
Instruction Manual 4.6. 1. PC 10 Calibrating for Conductivity: Pour out two separate portions of your calibration standard and one of DI water into separate clean MEAS READY mS containers. 2. If necessary, press MODE key to select °C ATC Conductivity Mode. The µS and mS indicator will appear on the right side of the display. 3. Rinse your probe with DI water, then rinse the probe in one portion of the calibration standard.
Instruction Manual 6. PC 10 Press the ENTER key to confirm calibration. Upon confirmation, the CON indicator appears briefly. The meter automatically switches back into Measurement mode. The display now shows the calibrated, temperature compensated conductivity value. See Figure 21. 7. For calibration in other ranges (maximum: four ranges) repeat steps 1 through 6 with the appropriate calibration standards.
Instruction Manual PC 10 5 . M EA SUR EM EN T The READY indicator appears on the display when the readings stabilise. It will turn off if the readings MEAS pH start to fluctuate. NOTE: Be sure to remove the protective cap of the pH electrode before measurement. °C ATC To take readings: 1. Rinse the probe with DI water before use to remove any impurities adhering to the probe body. If the pH electrode has dehydrated, Figure 19: Measurement mode soak it for 30 minutes in tap water. 2.
Instruction Manual PC 10 6. HOLD FUNCTION This feature lets you freeze the value of the pH or conductivity reading for a delayed observation. HOLD can be used any time when in MEAS mode. 1. To hold a measurement, press the HOLD key while in measurement mode. “HOLD” will appear on the display. See Figure 25. 2. To release the held value, press HOLD again. Continue to take measurements.
Instruction Manual PC 10 7. PROB E CAR E AND MA INTENANC E Under typical operating conditions, the probe will need to be replaced every 6 to 12 months. In extreme applications, the probe may wear out sooner. Proper care and maintenance will help you receive the maximum probe life and ensure more accurate readings. Keep the probe clean. Before use, rinse the probe twice. Be sure to remove the protective cap of the pH probe before use and always immerse the probe beyond the electrode band.
