5 Adjust the knob for the desired ou tput current.
Check that the Limit annunciator still blinks. Set the knob for current control .
The second digit of the ammeter will be blinking. Change the blinking digit
using the resolution selection keys and adjust the knob to the desired output
current.
6 Return to the meter mod e.
Press key or let the display time-out after sev eral sec onds t o return 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 8V * (or 25V **) o r 20V * (or 50V **), OVP ,
OCP and CC annunciators are lit. Notice that the displa y is in the meter mode.
In the meter mode, the display shows the actual output voltage and current.
Refer to “Programming Overvoltage Protection” and “Programming
Overcurrent Protection” sections, starting on
page 30 and page 34 for more
inform ation on OVP and OCP annunciators.
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 li t, 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:
