Output Inspection
Output inspection is to ensure that the instrument can achieve its rated outputs and
properly respond to operation from the front panel. For the procedures below, it is
suggested that you read "
Turn On/Off the Output
" on P14 and "
Set the Output
Voltage/Current
" on P14.
4.4.1
Voltage Output Inspection
The following steps verify basic voltage functions without load:
(1)
When the instrument is under no load, power on it; make sure that the output current
setting value is none-zero.
(2)
Turn on the channel output. The
ON/OFF
and
Volt/CV
key is lighted, which
indicates the channel you opened is in Constant Voltage output mode.
(3)
Set some different voltage values; check if the actual voltage value displayed is close
to the set voltage value, and to check if the actual current value displayed is nearly
zero.
(4)
Check that if the output voltage can be adjusted from zero to the maximum rating
30V.
4.4.2
Current Output Inspection
The following steps check basic current functions with a short across the power supply's
output:
(1)
Power on the instrument.
(2)
Connect a short across (+) and (-) output terminals with an insulated test lead. Use a
wire size sufficient to handle the maximum current 3A.
(3)
Set the output voltage to the maximum rating 30V.
(4)
Turn on the channel output. The
ON/OFF
and
Curr/CC
key is lighted, which
indicates the channel you opened is in Constant Current output mode.
(5)
Set some different current values; check if the actual current value displayed is close
to the set current value, and to check if the actual voltage value displayed is nearly
zero.
(6)
Check that if the output current can be adjusted from zero to the maximum rating 3A.
(7)
Turn off the channel output and remove the short wire from the output terminals.
