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.

7.2 Single Point Calibration:
7.2.1 Press the MODE key until the meter shows the indicator.
7.2.2 Rinse the conductivity electrode with distilled water, then rinse with a small amount of
calibration solution.
7.2.3 Press the CAL key; the meter enters the calibration mode.
7.2.4 Immerse the conductivity electrode in the calibration solution. The meter automatically
shows the detected calibration standard (e.g., 1413µS/cm).
