1.8 Performing Zero Adjustment
This section describes how to correct misalignment of inputs and set the instrument’s reference
voltage to 0 V.
Perform zero adjustment if the reference voltage is not 0 V with a pair of input terminals short-
circuited.
Zero adjustment is performed as follows:
1
Press the ENTER key while [Zero-adj] is selected on the waveform screen.
1 1
Zero adjust
ment values are reset when a system reset is performed. Zero adjustment cannot be
performed while meas
urement is in progress.
The internal temperature of the instrument and modules will stabilize once at least 30 minutes
has elapsed since they were turned on. Temporal variation can be limited by performing zero
adjustment in this state.
The zero adjustment function is disabled for Strain Units (U8554, LR8534).
To adjust the zero position of Strain Units, use the auto-balancing function.
For more information about auto-balancing, see “Measuring strain” (p. 27).
Zero adjustment can also be performed on the settings list screen.
