Instruction Manual 4 PC 510 PREPARATION 4.1 Connecting the Sensor Electrode 4.1.1 To connect the pH electrode: 1. Slide the BNC connector of the probe over the BNC connector socket on the meter. Make sure the slots of the connector are in line with the posts of the socket. Rotate and push the connector clockwise until it locks. 2. To remove electrode, push and rotate the connector anti-clockwise.
Instruction Manual 5 5.1 PC 510 CALIBRATION Important information on meter calibration When you calibrate your meter, old calibration points are replaced on a “point by point” basis in pH, and on a “range by range” basis in conductivity or TDS. For example: • pH: if you previously calibrated your meter at pH 4.01, 7.00 and 10.01, and you recalibrate at pH 7.00, the meter retains the old calibration data at pH 4.01 and pH 10.01.
Instruction Manual 5.3 PC 510 pH calibration NOTE: We recommend that you perform at least a 2-point calibration using standard buffers that bracket (one above and one below) the expected sample range. 5.3.1 Preparing for pH calibration This meter is capable of up to 5-point pH calibration to ensure accuracy across the entire pH range of the meter. Select from the following buffer options: • USA: pH 1.68, 4.01, 7.00, 10.01 and 12.45 • NIST: pH 1.68, 4.01, 6.86, 9.18 and 12.
Instruction Manual • PC 510 If you are performing one-point calibration, go to step 9. 7. Rinse the electrode with de-ionised water or rinse solution, and place it in the next pH buffer. CAL READY 8. Follow steps 5 to 7 for additional calibration points. 4.15 4.01 9. When calibration is complete, press CAL/MEAS to return to pH measurement mode. pH pH ENTER RANGE CAL READY NOTE: To exit from pH calibration mode without confirming calibration, DO NOT press ENTER in step 6. Press CAL/MEAS instead.
Instruction Manual 5.4 PC 510 Conductivity/TDS calibration The PC 510 has 5 measuring ranges. You can calibrate 1 point each of the measuring ranges (up to 5 points). If you are measuring values in more than 1 range, make sure to calibrate each of the ranges you are measuring. All new calibration data will over-ride existing stored calibration data for each measuring range you calibrate.
Instruction Manual PC 510 MEAS Calibrating for Conductivity: 1409 1. If necessary, press the MODE key to select conductivity mode. 22.3 2. Rinse the probe thoroughly with de-ionised water or a rinse solution, then rinse with a small amount of calibration standard. 3. If necessary, ensure that the probe’s yellow probe guard is attached. Dip the probe into the calibration standard. Immerse the probe tip beyond the upper steel band. Stir the probe gently to create a homogeneous sample.
Instruction Manual 5.5 5.5.1 PC 510 TDS Calibration MEAS Calibrating for TDS directly 265 The factory default setting for TDS conversion factor is 0.5. If your solution has a different TDS factor, you can improve calibration accuracy by setting the TDS factor prior to calibration. See Program P7.4 on page 36 for directions. 1. If necessary, press the MODE key to select TDS mode. 25.8 ppm °C ATC CAL MEAS 2.
Instruction Manual 5.6 PC 510 Calibration with Conductivity Standard and TDS factor The concentration of salts dissolved in solution increases the conductivity of that solution. This relationship varies from salt to salt and is roughly linear over a given range for a given salt. The TDS conversion factor is the number used by the meter to convert from conductivity to TDS. Instead of calibrating for TDS directly (described above), you can calibrate the PC 510 bench meter by: 1.
Instruction Manual 5.7 PC 510 Temperature Calibration MEAS The conductivity electrode (EC-CONSEN91W / 35608-50) supplied has a built-in temperature sensor. Alternatively, a separate temperature sensing element can be used (such as temperature probe EC-WPPHTEM-01W / 35618-05), or a “3-in-1” pH/Temperature combination electrode with ATC connection. The conductivity probe is factory calibrated.
Instruction Manual 6 PC 510 MEASUREMENT 6.1 6.1.1 Taking pH Measurements Automatic Temperature Compensation Automatic Temperature Compensation only occurs when a temperature sensing element is plugged into the meter.

Instruction Manual 6.1.3 PC 510 Taking pH Measurements Be sure to remove the electrode storage bottle or protective rubber cap on the electrode before measurement. MEAS 8.23 To take readings: 1. Rinse the pH electrode with de-ionised or distilled water before use to remove any impurities adhering to the probe body. If the pH electrode has dehydrated, soak it for 30 minutes in electrode storage solution or 2M – 4 M KCL solution (sold separately). pH °C 21.3 ATC Figure 15: Measurement mode 2.

Meter default is ATC on. Figure 17: P7.0 configuration setup for conductivity & TDS From Conductivity or TDS measurement mode 1.
Instruction Manual 6.2.3 PC 510 Setting a manual temperature compensation value To use manual temperature compensation, you need to enter the temperature value of your process into the meter. This is the value at which reading will manually temperature compensate. You can select any temperature between 0 and 100 °C (32 to 212 °F). Default value is 25 °C (77 °F). To select a manual temperature compensation value 1. Switch the meter on. Press the MODE key to select conductivity or TDS measurement mode.
Instruction Manual PC 510 4. If necessary, ensure that the probe’s yellow probe guard is attached. Dip the probe into the sample. When dipping the probe into the sample, take care to ensure that the liquid level is above its upper steel band. Stir the probe gently in the sample to create a homogeneous sample. 5. Allow time for the reading to stabilise. Note the reading on the display. If the READY indicator is selected on, it will appear when the reading is stable. See Program P7.
