2.2 General Inspection
When you have got a new power supply, it is suggested that you should
perform a general inspection on the instrument according to the following
steps.
Check whether there is any damage on it due to transportation
If the packing boxes or foam cushions are found to have serious damage, keep
them in a safe place until the complete instrument and accessories have
passed the electrical and mechanical tests.
Check the accessories
Check that all the parts and accessories are included and in serviceable
condition.
Check the complete instrument
If the instrument is damaged in its appearance or it fails in normal operation or
performance test, do not use it and contact the supplier directly.
2.3 Power Inspection
(1) Use the power cord supplied with the accessories to connect the
instrument to the AC power.
Warning：
To prevent electric shock, make sure that the instrument is
properly grounded.
(2) Press the power button on the front panel, the button light will be on, and
the startup screen will be displayed on the screen.

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.

3.1.3 Over Voltage/Current Protection
When the Over Voltage Protection (O.V.P) or Over Current Protection (O.C.P)
is enabled, once the output voltage/current reaches the set value of
O.V.P/O.C.P, the instrument will cut off the output, a warning will show on the
screen.
Note:
When the instrument disables the output due to protection, after you
make some adjustments, the channel must be restarted to output
normally.
This function can keep the power output from exceeding the load rating to
protect the load.

7. Troubleshooting
1. The instrument is powered on but no display showing.
Check if the power is connected properly.
Check if the fuse which is below the AC Power socket is used
appropriately and in good condition (the cover can be pried open with a
straight screwdriver).
Restart the instrument after the steps above.
2. The output is abnormal:
Check if the output voltage is set to 0V. If so, set it to other value.
Check if the output current is set to 0A. If so, set it to other value.
When in programmable output status, check if there is any
voltage/current value is set to 0. If so, set it to other value.
