40ENTER 705; B$

50DISP A$,B$

60GOTO 10

70END

Turn OVP ADJUST potentiometer counterclockwise while observing VOUT and OVP readings on computer display. VOUT should drop to about 0 volts as OVP is adjusted below 10 volts. Stop program. Send string:

STS?

And address the power supply to talk. The response should be:

STS 8

indicating that the OVP circuit has tripped. Turn OVP ADJUST potentiometer fully clockwise. Send String:

RST

Restart program. VOUT should read 10 volts. Stop program.

c.To check constant current circuit, turn power supply off and connect a wire capable of handling the full current of the power supply across + and - terminals on rear panel.

d.Turn power supply on and send the appropriate string in Table B-2.

e.Turn off power supply, remove short from output, and read remainder of Section 3, except for LOCAL OPERATION, before connecting load to supply.

Overvoltage Protection Setting

For ease in setting the OVP trip voltage, use a looping program such as that listed in the check out procedure. This enables you to read the OVP trip voltage on the computer display while adjusting OVP at the power supply front panel.
