Two-point Calibration
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.
