6.2 ORP Calibration Report
The meter allows checking the mV offset of the ORP electrode for diagnostic purposes.
1. Press the mR key in the ORP measurement mode, the display shows “LOC/P-01”.
2. Press ▲ or ▼ key until the meter shows “ELE/P-02” (Electrode Diagnosis).
3. Press ENTER key to confirm, the meter shows the last calibration date (Format: mm-dd).
4. Press ▼ key, the meter shows “OFS” (Offset Potential).
5. Press the ON/OFF key to return to measurement mode
7.1 Conductivity Calibration
The HC1000 is capable of using conductivity electrodes with different cell constants.
Before use, ensure that the correct cell constant is selected (0.1, 1 or 10) in the setup menu.
If the current option is “USER”, the automatic calibration function will be disabled (Refer to
Setup Menu section).
In the automatic calibration mode, the meter allows up to a 5 point calibration. To ensure
higher accuracy, at least a 3 point calibration is recommended. Alternatively, it is advised to
select a standard value close to the sample value under measurement.
The meter will automatically detect common conductivity standard solutions and prompt the
user to calibrate the meter.
When the calibration is completed, all new calibration values will automatically override
existing data.
The following table shows acceptable conductivity range of calibration solution for each
measuring range.
