(4) Inspect the voltage function of +25 V channel.
Press +25V and the corresponding On/Off key. The On/Off key is
illuminated and the channel is in constant voltage output state. Inspect
whether the voltage can be adjusted from 0 to the maximum rated value
(26.25 V).
(5) Inspect the voltage function of -25 V channel.
Press -25V and the corresponding On/Off key. The On/Off key is
illuminated and the channel is in constant voltage output state. Inspect
whether the voltage can be adjusted from 0 to the minimum rated value
(-26.25 V).
3. Current Output Inspection
(1) Press .
(2) Press All Off to disable the outputs of all the three channels.
(3) Inspect the current function of +6 V channel.
Use an insulated test lead to short-circuit the (+) and (-) output
terminals of +6 V channel.
Press +6V.
Set the voltage to 6 V.
Press the On/Off key corresponding to the +6 V channel.
After the On/Off key is illuminated, inspect whether the current can be
adjusted from 0 to the maximum rated value (5.25 A).
(4) Inspect the current function of +25 V channel.
Use an insulated test lead to short-circuit the (+) and (COM) output
terminals of +25 V channel.
Press +25V.
Set the voltage to 25 V.
Press the On/Off key corresponding to the +25 V channel.
After the On/Off key is illuminated, inspect whether the current can be
adjusted from 0 to the maximum rated value (1.05 A).
(5) Inspect the current function of -25 V channel.
Use an insulated test lead to short-circuit the (-) and (COM) output
terminals of -25 V channel.
Press -25V.
Set the voltage to -25 V.
Press the On/Off key corresponding to the -25 V channel.
After the On/Off key is illuminated, inspect whether the current can be
adjusted from 0 to the maximum rated value (1.05 A).
