Preparing the Meter for Calibration
Before starting calibration, make sure you are in the
correct measurement mode.
pH Calibration
NOTE: We recommend that you perform at least 2-
point calibration using standard buffers that bracket
(one above and one below) the expected sample
range.
Preparing for pH Calibration
The meter automatically recognises and calibrates
to these standard buffer values, which makes pH
calibration faster and easier.
Be sure to remove the protective electrode
storage bottle before calibration or
measurement.
Wash your electrode in deionised water before
and after calibration/use, and store in the
protective electrode storage solution.
Do not reuse buffer solutions after calibration.
Contaminants in the solution can affect the
calibration and eventually the accuracy of the
measurements.
