"
2.
Connect a digital voltmeter to
TP51 (IOPDVD) and

the value of digital voltmeter
.
4.
Divide the measured voltage value by 1, and convert it into
current value.
5.
Check
that
the
calculated
value
is
within
±6
mA
to
the
IOP
value given on the label.
6.
Connect
a
digital
voltmeter
to
TP47
(IOPCD)
and
