Chapter 4 Viewing Measurement Values
Execute zero adjustment to compensate for input signal bias before measuring analog DC voltage on CH
A or CH B.
If a non-zero value is displayed for torque or rotation rate when no torque or rotation is occurring, execute
zero adjustment before applying any torque or rotation input.
Executing Zero Adjustment
• This particular zero adjustment function applies only to the motor analysis function, so the
other input channels (CH 1 to CH 4) are unaffected. To execute zero adjustment on those chan-
nels, see section "3.11 Attaching to the Lines to be Measured and Zero Adjustment" (p. 41).
• Zero adjustment is only applicable to analog DC input channels.
• The maximum zero adjustment span is ±10% of the full-scale range, outside of which no
adjustment occurs.
