4 Turn on the power system and program the instrument settings
as described in the test record form under “CC Source Effect”.
5 Set the electronic load for the output channel’s voltage under “CC
Source Effect”. The CC annunciator on the front panel must be
on. If it isn’t, adjust the load so that the output voltage drops
slightly.
6 Adjust the transformer or AC source to the lowest rated line
voltage (86 VAC).
7 Divide the voltage drop (DVM reading) across the current
monitoring resistor by its resistance to convert to amps and
record this value (Iout).
8 Adjust the transformer or AC source to the highest rated line
voltage (264 VAC).
9 Divide the voltage drop (DVM reading) across the current
monitoring resistor by its resistance to convert to amps and
record this value (Iout). The difference between the DVM reading
in steps 6 and 8 is the source effect, which should not exceed the
value listed in the test record form for the appropriate model
under “CC Source Effect”.
