Event log

The controller provides one event log for each sensor. The event log stores a variety of events that
occur on the devices such as calibrations done, calibration options changed, etc. A list of possible
events is shown in
Table
downloading the logs, refer to the controller user manual.

Clean the pH sensor, then repeat
the calibration with a fresh buffer
or sample, or replace the sensor.
Clean the sensor and replace the
salt bridge and standard cell
solution and then repeat the
calibration, or replace the sensor.
