The calibration input voltages are arbitrary but the following points are suggested for
each of the ranges:
Input Range Low cal point High cal point
50 ohm 1mV 9mV
100 ohm 2mV 18mV
250 ohm 5mV 45mV
500 ohm 10mV 90mV
Always calibrate the 10mV range. This is used for the sense lead input calibration.
Separate modes exist for calibration of the low and high point. Prior to calibration
ensure that the following parameters are reset to their default values:
Parameter Value Parameter Value
Filter_Time 0s Post_Scaler 1
Pre_Scaler 1 Post_Offset 0
Pre_Offset 0
