Display Explanation
Restores the output sense connections. The Prot
annunciator is still on.
NO FAULT Clears the protection condition. Prot is off; CV is on.
VOLT 0.000 Display shows the output voltage setting of the unit.
VOLT <15> Programs the main output to 15 volts. After the value
15.003V 0.0001A is entered, the display returns to Meter mode.
Because the output is enabled, the meter will indicate
the actual output voltage.
0.000V 0.0000A Turn the output off.
Shorts the output of the unit.
0.004V 3.0712A The CC annunciator is on, indicating that the unit is
in constant current mode. The unit is sourcing output
current at the maximum rating, which is the default
output current limit setting.
CURR <1> Programs the output current to 1 ampere.
0.001V 0.0003A You enabled the overcurrent protection circuit. The
circuit then tripped because the unit was operating in
constant current mode. The CC annunciator turns off,
and the OCP and Prot annunciators turn on.
0.001V 0.0003A You have disabled the overcurrent protection circuit.
The OCP annunciator turns off.
0.004V 0.998A Restores the output. The Prot annunciator turns off.
The CC annunciator turns on.
The next time the unit turns on it will be restored to

0.025V 0.0002A Shift Channel toggles between channel 1 and channel
2. The left-most digit of the display identifies the
output channel that is presently being controlled. It will
indicate a "1" for channel 1, or "2" for channel 2.

12.005V 0.0002A Turns the main output and output 2 on. The Dis
annunciator is off, but the CV annunciator is on.
