Oakton EC1 - Self-Diagnosis Functions; Factory Calibration and Accuracy Check; Parameter Setting; Parameter Setting Procedure

5.2 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.
5.3 Unit Information: 1 mS/cm = 1000 µS/cm
Once the readings are greater than 2000µS/cm, the unit will automatically
become mS/cm.
5.3 The tester has self-diagnosis functions:

How to fix
Wrong calibration solution,
which exceeds the
recognizable range of the
meter.
1. Check if calibration solution is
correct
2. Check if probe is damaged.

5.4 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.
