3 Program the output voltage to full rated voltage (8.0 V)
[1]
or (25.0 V)
[2]
and
output current to zero amps by sending the commands:
4 Divide the voltage drop (DVM reading) across the current monitoring resistor
(R
M
) by its resistance to convert to amps and record this value (I
O
). This value
should be within the limit of (0 A ± 10 mA). Also, note that the CC, Adrs, Limit,
and Rmt annunciators are on.
5 Readback the output current over the remote interface by sending the
command:
6 Record the value displayed on the controller. This value should be within the
limit of (I
O
± 5 mA).
7 Program the output current to the full rated value (20.0 A)
[1]
or (7.0 A)
[2]
by
sending the command:
8 Divide the voltage drop (DVM reading) across the current monitoring resistor
(RM) by its resistance to convert to amps and record this value (I
O
).
This value should be within the limit of (20 A ± 50 mA)
[1]
or (7A ± 24 mA)
[2]
.
9 Readback the output current over the remote interface by sending the
command:
