4.4 Selection of Automatic or Manual Calibration
This meter is capable of performing either automatic conductivity calibration or
manual conductivity / TDS calibration.
In the automatic calibration mode, the meter automatically detects and verifies the
appropriate known calibration standards solutions before accepting these particular
calibration standards as one of its calibration values in a specific measurement
range. This automatic calibration mode frees you from cumbersome calibration
procedure.
The known calibration standards used for automatic calibration are:
Meter Temperature Normalisation
(tnr °C)
Calibration Standards (Range)
25.0 °C 84 µS (for 0 – 200 µS/cm)
1413 µS (for 0 – 2000 µS/cm)
12.88 mS (for 0.00 – 20.00 mS/cm)
111.8 mS (for 0.0 – 200.0 mS/cm)

In the manual calibration, non-standard calibration values can be used for calibration.
You can manually input the appropriate values as your desired calibration standards
in each specific range. This is useful when you have a customised calibration
standard specifically unique for your application.
