Manual Calibration
User inputs are calculated with the following formula:
Calibrated value = Scaler x (Raw Value) + Offset
Manual calibration allows direct entry of the
“
Scaler
”
and
“
Offset
”
quantities. The same formula is used in the 2-point calibration. The 2-
point calibration procedure automatically calculates the
“
Scaler
”
and
the
“
Offset
”
.
