•
To exit calibration, press ON/OFF key; the meter will return to measurement mode
immediately.
•
Performing the conductivity calibration will simultaneously calibrate the corresponding
TDS, salinity and resistivity value.
7.5 Conductivity Calibration Report
The meter allows checking of the calibration factor of the conductivity electrode for
diagnostic purposes.
1. Press the MR key in the conductivity 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 calibration point and calibration factor (e.g., K=0.998).
5. After the browsing, press MEAS key to exit the current mode.
EXIT THE CALIBRATION:
To exit calibration, press the ON/OFF key at any point; the meter will return to measurement
mode immediately.
8.1 DO Calibration in % Saturation Mode
The HC1000 dissolved oxygen probe can be calibrated quickly in air. In the percentage
saturation mode, the meter is able to perform either 1 or 2 points calibration. For single point
calibration, it is recommended to perform 100% saturation calibration in air. For the 2 point
calibration, the second point should be saturated anhydrous sodium sulfite solution (zero
oxygen solution).
8.2 100% saturation calibration:
8.2.1 Press MODE key until the meter shows indicator and measurement unit “%”.
