3 Verify that the correct power-line fuse is installed.
The correct fuse for your country is installed when the power supply is shipped
from the factory. See the table below to replace the fuse for your power supply.
Checking the instrument output
The following procedures check to ensure that the power supply develops its
rated outputs and properly responds to operation from the front panel. For
complete performance and verification tests, refer to the U8030A Series Service
Guide .
From the front-panel VFD (vacuum-fluorescent display), you can monitor actual
values of output voltage and current (meter mode) or voltage and current limit
values (limit mode).
Voltage output check
The following steps verify basic voltage functions with no load.
1 Turn on the power supply.
The power supply starts up for the first time in the power-on (reset) state — all
the outputs are disabled (the OFF annunciator is turned on).
2 Enable the outputs.
Press the
[All On/Off] button once. Notice that the display is in the meter
mode.
