    Instruction Manual pH 5+, pH 6+, Ion 6+ BNC connector of pH, ORP, or Ion electrode 2.5 mm Phono plug for temperature measurement Insert the mini phono jack of temperature sensor into the socket on the meter. Unplug the phono jack when not in use or you measure pH without any temperature compensation.

  • Page 10: Calibration

    Instruction Manual pH 5+, pH 6+, Ion 6+ 3. CALIBRATION 3.1 pH Calibration The meter is capable of calibrating up to 3 pH values using USA or NIST (nSt) pH buffer standards or 2 pH values with Low Ionic (Pb) pH buffer standard. All new calibration values will automatically override existing data.

    Instruction Manual pH 5+, pH 6+, Ion 6+ 3. Press CAL to enter pH calibration mode. “CA” displays momentarily before the display flashes the current un-calibrated reading. 4. To abort or cancel calibration without accepting the new value, press CAL key. The meter will automatically revert to pH measurement mode.

  • Page 12: Resetting User Calibrated Values

    Instruction Manual pH 5+, pH 6+, Ion 6+ Press ENTER key to confirm your selection. The meter will automatically revert to pH measurement mode. The meter will save the selected group indefinitely until changed. 3.1.3 Resetting User Calibrated Values The calibrated pH/mV/Ion values can be reset to factory default using the procedure below.

  • Page 13: Ion Calibration Procedure

    Instruction Manual pH 5+, pH 6+, Ion 6+ available include 0.1, 1.0, 10.0, 100.0 ppm. Recalibrate and ensure that consecutive calibration points are 1 decade apart from each other. Ensure that you use new or fresh standard solutions during calibration. Do not reuse ion standard solution as it may be contaminated and affect the calibration and accuracy of measurements.
  • Page 14 Instruction Manual pH 5+, pH 6+, Ion 6+ 3. Press ENTER to confirm that the ppm value is the desired standard. The displayed value now shows the corresponding mV reading for the selected ppm value selected. Allow the reading to stabilise. 4.

  • Page 15: Millivolt (Mv) Calibration (Ph 6+ Only)

    Instruction Manual pH 5+, pH 6+, Ion 6+ If the calibration is not successfully stored into its memory, an error message “Er3” will be displayed. This occurs when the slope is lower than 15mV/decade or higher than 90mV/decade. 3.3 Millivolt (mV) Calibration (pH 6+ only) mV calibration is performed for Oxidization Reduction Potential (ORP / Redox) measurements, where you can adjust its mV value as a base value for measurements.

  • Page 16: Temperature Calibration

    Instruction Manual pH 5+, pH 6+, Ion 6+ 3.4 Temperature Calibration 3.4.1 With Temperature Probe The temperature probe (ECPH5TEM01P) provided with the meter is factory-calibrated. Over time, temperature calibration may drift and require calibration. If there is a need to replace with the new probe you should calibrate the temperature probe prior to pH calibration.

  • Page 17: Without Temperature Probe (No Atc)

    Instruction Manual pH 5+, pH 6+, Ion 6+ 3.4.2 Without Temperature Probe (no ATC) If no temperature probe is used, the meter compensates for pH response based on a temperature value manually set by you or at 25.0 C (factory default). 1.

    Instruction Manual pH 5+, pH 6+, Ion 6+ 4. MEASUREMENT 4.1 Taking Measurements 1. Before measurement, rinse pH/ORP electrode or Ion Selective Electrode temperature probe with clean water to remove any impurities stuck onto the bodies of probes. 2. Power on the meter using ON/OFF key. Press MODE key to select your desired mode of operation (pH, mV, Ion, or Temperature).
