Calibration Pass/Fail
On completion a calibration status message is displayed.
Calibration Pass: Calibration sequence successful
Failed Constant: Cell offset >±10mV
(upper display shows cell constant)
Failed Span %: Cell output <90% or >110% of slope
(upper display shows measured slope)
Failed Unstable: Cell output unstable (drifting).
Note. If sensor calibration is unsuccessful then the Cell Zero mV and Span
% of Theory parameters are unaffected. The instrument continues to operate
using parameters stored during the last successful calibration.
