Table 3-2. Checking the Current Functions (Output Terminals Shorted)
Turn off the power supply and connect a wire across the output (+) and (-) terminals. Use a wire of sufficient size to
carry the maximum current of the supply (see "Performance Specifications" in Chapter 1).
Turn on the supply

Essentially zero outputs with
Dis
annunciator on.
Press
VOLT 1.500
Set a minimum operating voltage to cause current to low.
Press
Dis
annunciator goes off,
CC
annunciator comes on, and
AMPS display shows some current. If there is no current and
CV
annunciator remains on, increase the operating voltage
setting.
Press

*Current increases about 7 milliamperes each time you press
the key.
Press
the same number of
times
*Current decreases about 7 milliamperes each time you press
the key.
Rotate the Current control first
clockwise and then counterclockwise.
Control operates similarly to the
and
keys. Turning the controls more quickly causes a more rapid
change in current.
Press
You have enabled the overcurrent protection circuit, which
tripped because of the output short. The
CC
annunciator goes
off and the
OCP
and
Prot
annunciators come on. The output
current is near zero.
Press
OC
Indicates the overcurrent protection circuit has tripped. (see
“Supplemental Characteristics” in Chapter 1).
