5 Adjust the knob for the desired output current.
Check that the
Limit annunciator still flashes. Set the knob for current control. Change
the flashing digit using the resolution selection keys and adjust the knob to the desired
output current.
6 Return to the meter mode.
Press or let the display time-out after several seconds to return to the meter
mode. Notice that the
Limit annunciator turns off and the display shows “OUTPUT
OFF” message.
7 Enable the output.
The
OFF annunciator turns off and the CC annunciator turns on. Notice that the display
is in the meter mode.
8 Verify that the power supply is in the constant current mode.
If you operate the power supply in the constant current (CC) mode, verify that the
CC
annunciator is lit. If the
CV annunciator is lit, choose a higher voltage limit.
Note During actual CC operation, if a load change causes the voltage limit to be exceeded,
the power supply will automatically crossover to constant voltage mode at the preset
voltage limit and the output current will drop proportionately.
• Remote interface operation:
VOLTage {<voltage>|MIN|MAX} Set the voltage

You can use the resolution selection keys to move the flashing digit to the right or
