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

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.
N o t e
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.
