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.
