WARNING :
The Reset function will restore the unit back to factory default settings, all calibration values and
selected parameters will be reset.
10. Press CAL key to enable or disable the reset function. Press ENTER key to confirm, the unit returns
to measurement mode. Setting is completed.
EXIT THE SETUP MENU:
During the setup mode, to exit the setup menu, press ON/OFF key; the unit will return to measurement
mode immediately.
Conductivity Calibration
The HL102 pocket EC/TDS/temperature tester allows up to 3 point calibration in the conductivity mode.
To ensure higher accuracy, we recommend that you perform a 3 point calibration, or select a calibration
standard concentration close to the sample value you are measuring. For typical environmental
freshwater samples, 1413µS/cm should be sufficient. The unit will automatically detect these conductivity
standard solutions and prompt the user to calibrate the meter. When the calibration is done, all new
calibration values will automatically override existing data. The following table shows acceptable
conductivity ranges of calibration solution for each measuring range.

0~20µS/cm 7~17µS/cm 10µS/cm
20~200µS/cm 70~170µS/cm 84µS/cm
200~2000µS/cm 700~1700µS/cm 1413µS/cm
2~20mS/cm 7~17mS/cm 12.88mS/cm
Ensure that you use fresh conductivity standard solution during the calibration. Do not reuse calibration
solutions as it may be contaminated and affect the calibration and accuracy of measurement.
SINGLE POINT CALIBRATION:
1.1 Rinse the conductivity electrode with distilled water, then rinse with a small amount of calibration
solution.
1.2 Press CAL key; the unit enters calibration mode.
