HIGH-SPEED ANALOG OUTPUT

4.4 Instructions

(1) A voltmeter having smaller internal impedance than the value indicated in the Specifications (page 4)
may not deflect to full-scale and may not be calibrated.
(2) To calibrate a voltmeter, of which full scale is less than 10VDC, disconnect the voltmeter first. Then,
set terminal DA2 to DA5 outputs to the smallest values (set scale ratios to Pr.526, Pr.528, Pr.530, and
Pr.532) according the voltmeter, and reconnect the voltmeter.
At the time of shipping, full-scale output is set to 10VDC. If a voltmeter, of which full scale is
less than 10VDC, is calibrated with the default setting, the voltmeter may be damaged. Make
sure to set the scale ratios according to the voltmeter.
(3) When an option error (

to ) occurs, all outputs are off.
