1. INTR ODUCTION Thank you for selecting Eutech Instruments portable meter. The Eutech Standard/Waterproof PC 10 portable meter is a microprocessor-based 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 a combination pH / conductivity / temperature probe with 3-metre submersible cable and batteries.
2. D ISPLAY AND K EYPAD FU NCTION S 2.1. Display The LCD has a primary and secondary display. x The primary display shows the measured pH or conductivity (µS or mS) reading. x The secondary display shows the temperature of the reading in °C. The display also shows error messages, keypad functions and program functions. See Figure 2.
2.2. 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 ON/OFF Function Powers on and shuts off the meter. When you switch on the meter, the meter starts up the mode you shut it 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.
3. PR EPARATION 3.1.1 Inserting the Batteries (Standard CyberScan PC 10) The CyberScan is packaged with 4 “AAA” alkaline batteries required for operation. To insert the batteries into the CyberScan, follow the procedure outlined below. 1. To open the battery compartment, press down the catch of the battery cover. See Figure 4a below. 2. Note the polarity and insert the batteries into the battery compartment correctly (Figure 4b). 3.
3.1.2 Inserting the Batteries (Waterproof CyberScan PC 10) Four AAA batteries are included with your meter. 1. Use a Philips screwdriver to remove the two screws holding the battery cover. See Figure 5 below. 2. Remove battery cover. 3. Insert batteries. Follow the diagram inside the cover for correct polarity. 4. Replace the battery cover into its original position using the two screws removed earlier.
3.2 Connecting the probe The Eutech Instruments Standard/Waterproof PC 10 meter uses a specialty 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, pages 23 - 24. NOTE: Keep connector dry and clean. Do not touch connector with soiled hands. To connect the pH / Conductivity probe: 1.
3.3. Connecting the AC Adapter (only for Standard PC10 meter) The AC adapter is not included with your meter; order separately. See the “Accessories” section on pages 23 - 24. 1. 2. Insert the AC jack as shown in Figure 7 below. Switch off the meter before plugging the adapter into the power source. This safety precaution protects the software in your meter. 3. Press the ON/OFF button to switch meter on.
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.
4.2. 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, pages 23 - 24. Be sure to remove the protective rubber cap of the probe before calibration or measurement. Immerse the probe in tap water for 10 minutes before calibrating or taking readings to saturate the pH electrode surface and minimize drift.
3. Dip the probe into the calibration buffer. The end of the probe must be completely immersed into the sample. Stir the probe gently to create a homogeneous sample. 4. Press CAL/MEAS to enter pH calibration mode. The primary display will show the measured reading while the smaller secondary display will indicate the pH standard buffer solution. Figure 9 - Calibration at pH 7.00 See Figure 9.
7. Press the V or W key to select the next buffer value you want to calibrate (pH 4.00, 7.00 or 10.00). See Figure 12. 8. Rinse the probe with de-ionized water or a rinse solution, and place it in the next pH buffer. 9. Follow steps 5 to 8 for additional calibration Figure 12 - Next calibration point points (up to 3 values). 10. When calibration is complete, press CAL/MEAS to return to pH measurement mode.
4.4. Conductivity Calibration Ideally, you should select a conductivity standard with a value near the sample value you are measuring. The next best method is to choose a calibration solution value that is approximately 2/3 the full-scale value of the measurement range. For example, in the 0 to 1999 µS range, use a 1413 µS solution for calibration. See “Specifications”, page 22.
Calibrating for Conductivity: 1. Pour out two separate portions of your calibration standard and one of deionized water into separate clean containers. 2. If necessary, press the MODE key to select Conductivity Mode. The µS or mS indicator will appear on the right side of the display. 3. Rinse your probe with deionized water, then rinse the probe in one of the portions of Figure 13 - READY when reading is stable calibration standard. 4.
8. 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 16. 9. For calibration in other ranges (maximum: four ranges) repeat steps 1 through 9 with the Figure 16 - CONFIRM the calibration value appropriate calibration standards.
4.5. Temperature Calibration The built-in temperature sensor included in the probe is factory calibrated. Calibrate your sensor only if you suspect temperature errors that 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 Figure 17 - Enter pH Calibration mode CAL/MEAS calibration mode. key to enter pH The CAL indicator will appear above the primary display. See Figure 17. 3.
6. Press the ENTER key to confirm temperature calibration. The CON indicator will flash to confirm calibration. See Figure 20. NOTES To exit from Temperature Calibration mode without confirming calibration, DO NOT press ENTER in step 6. Press CAL/MEAS instead. Figure 20 – CONFIRM temperature calibration Temperature calibration is restricted to ±5°C from the initial value displayed during calibration (shown in the secondary display).
5 . M EA SUR EM EN T The READY indicator appears on the display when MEAS the readings stabilize. It will turn off if the readings pH start to fluctuate. NOTE: Be sure to remove the protective rubber °C ATC cap of the electrode before measurement. To take readings: 1. Rinse the probe with deionized or distilled water before use to remove any impurities Figure 21 - Measurement mode adhering to the probe body. If the pH electrode has dehydrated, soak it for 30 minutes in tap water. 2.
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 24. 2. To release the held value, press HOLD again. Continue to take measurements.
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. For the best accuracy, soak your probe in electrode storage solution, pH 4.0 buffer, or tap water for at least 5 to 10 minutes before calibration.
