Description
Calibration slope is too high or low.
Ensure correct pH buffers are used. Be sure a pH
probe is connected to the meter. Disconnect any
probe connected to the BNC connector.
The value read will not work in the calibration
algorithm.
Ensure one buffer was not measured twice and
that the correct buffers were used. If not, repeat
calibration with new buffers.
