6. Notes
6.1 The tester adopts 1413 µS and 12.88 mS standard calibration solutions. Users can
use 1-2 point calibrations as needed. For most circumstances, calibrating in 1413 µS to
complete 1
st
point calibration will meet testing requirements.
6.2 The tester has self-diagnosis functions:

exceeds the recognizable range of
the meter.
1. Check if calibration solution is
correct
2. Check if probe is damaged.

6.3 The tester has already been calibrated after manufacture. Usually, users can use
the tester right away, or test it in the calibration solutions to test its accuracy. When
error is large, calibrate it before using.
6.4 We recommend replacing new calibration solutions after 5-10 times of calibrations
to keep the solution’s accuracy.
