Comments
Select BENCH CAL.
SAME SENSOR:CALCULATED SENSOR OFFSET,
CALCULATED EFFICIENCY, and CUMULATIVE
OFFSET CHANGE are recalculated.
NEW SENSOR: CALCULATED SENSOR OFFSET,
CALCULATED EFFICIENCY are calculated and
CUMULATIVE OFFSET CHANGE is set to 0.00 mV.
NOTE: mV SOURCE selection is covered in
Calibration (mV).
Low default value: -1000 mV.
High default value: +1000 mV.
Enter low mV value and press
mV value.
Displays low mV calibration value, and the uncali-
brated mV values determined from the input source.
Displays high mV calibration value, and the uncali-
brated mV values determined from the input source.
Value from last calibration. If new sensor, efficiency
will be 98%.
This value is recalculated during each calibration.
