Measurement Adjustment Method
This instrument should be adjusted by a qualified engineer at a qualified facility with sufficient precision. The
adjustment feature of this instrument can be used to adjust the D/A output and voltage/current measurement.
The adjustment values are retained even when the instrument is initialized, but they may be reset if the
instrument is adjusted at a YOKOGAWA factory. If you need to adjust the instrument more than that is possible
with the adjustment feature or if you want calibration and adjustment to be performed at a YOKOGAWA factory,
contact your nearest YOKOGAWA dealer.
