Key-In Calibration:
The Key-In calibration method is typically only used in emergency cases when the
indicator cannot receive a Live calibration. The Key-In method uses a single point to
establish the span of the load cell. It ignores load cell nonlinearity and any asymmetry
between the opposing loading modes.

output of the load cell at its rated capacity. Press the Menu (Enter) button to save this
value.
