4.6 Instructions
(1) A voltmeter having smaller internal impedance (or an ammeter having larger internal impedance) than
the value indicated in the Specifications
(page 2)
may not deflect to full-scale and may not be calibrated.
(2) When calibrating a meter with a small full-scale value, set output of terminal AM0 and AM1 to minimum,
then connect a meter.
(3) Set "0%" in
Pr. 307
or
Pr. 311
and "100%" in
Pr. 308
or
Pr. 312
to prevent calibration value deviation when
calibrating the meter using
Pr. 323
,
Pr. 324
,
C0 (Pr. 900)
, or
C1 (Pr. 901)
when
Pr. 309
= "10 or 11".
(4) When an option fault (
) occurs, all outputs are off.
This option unit is factory-set to provide the full-scale output of 10VDC and 20mADC. Hence, a
voltmeter (7VDC or less) or an ammeter (14mADC or less) with a small full-scale value may be
damaged accidentally during calibration. This should be fully noted.
CAUTION
