To perform output adjustment, connect a digital voltmeter to the output terminal and set the
measurement screen in the Factory Adjustment mode.
Caution: Perform the output adjustment within the range of 4 to 2mA and 0 to 1V on the
Adjustment screen. If other adjustment screen appears and you are at a loss what to do
on the screen, press the ESC key several times to change it to the Measurement mode.
In this case, don’t press the ENT key. Otherwise the adjustment contents would change,
