Check that the
Limit
annunciator still flashes. Set the knob for

The second digit of the ammeter will be flashing. 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 key or let the display time-out after sev eral seconds t o return the

CC
annunciators are lit. Notice that the display is in the meter mode.
In the
meter
mode, the display shows the actual output voltage and current.
8 Verify that the power supply is in the constant current mode.
If you operate the power supply in the consta nt current (CC) mode, verify that
the
CC
ann unciator 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.
