2.4 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 Channel Output" on page
8 and "Set the Output Voltage/Current" on page 7.
2.4.1 Voltage Output Inspection
The following steps verify basic voltage functions without load:
(1) When the instrument is under no load, select a channel and ensure the
output current setting for this channel is not at zero.
(2) Turn on the channel output, then ensure the channel is in Constant
Voltage output mode.
(3) Set some different voltage values on this channel; check if the actual
voltage value displayed is close to the set voltage value, and also that the
actual current value displayed is nearly to zero.
(4) Check that if the output voltage can be adjusted from zero to the maximum
rating.
2.4.2 Current Output Inspection
The following steps check basic current functions with a short across the
power supply's output:
(1) Connect a short across (+) and (-) output terminals with an insulated test
lead on this channel. Use a wire size sufficient to handle the maximum
current.
(2) Set the output voltage to the maximum rating on this channel.
(3) Turn on the channel output. Ensure the channel you used is in Constant
Current output mode.
(4) Set some different current values on this channel; 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.
(5) Check that if the output current can be adjusted from zero to the maximum
rating.
(6) Turn off the channel output and remove the short circuit from the output
terminals.
