Operating Instructions

(1) Connect the instrument to an AC power source using the line cord
provided and turn the power switch ON. For maximum stability,
allow the instrument to warm up for at least 20 minutes.
(2) INDEPENDENT MODE - Set the FUNCTION switch to the INDE-
PENDENT mode. The two sets of voltage and current adjustment
knobs may then be used to set the outputs to the desired level.
(3) SERIES MODE - Set the FUNCTION switch to the SERIAL mode.
Using the master voltage adjustment knob, set the desired output
voltage.
(4) PARALLEL MODE - Set the FUNCTION switch to the PARALLEL
mode. Using the master voltage adjustment knob, set the desired
output voltage. (In PARALLEL mode, multiply the top current scale
by a factor of 2 for correct reading).
(5) 5V / 3A OUTPUT - Constant regulated 5V supply.
Please note the following cautions when using your power supply, to
prevent damage to the unit.
(1) Do not connect to equipment until all settings are complete.
(2) Verify that the AC voltage setting is the same as your available
power BEFORE you apply power for the instrument.
(3) Do not connect a voltage that is greater than the output voltage
to the terminals of the instrument.
(4) Do not short out the 5V / 3A output; this will cause the internal
4 Amp fuse to blow.
