If everything is OK, the VFD will display
voltage and current as follows:
CV Meter
5.65V 0.00A
Warning:
The power supply is shipped from the factory with a power-
line cord that has a plug appropriate for your location. Your power supply
is equipped with a 3-wire grounding type power cord; the third conductor
being the ground. The power supply is grounded only when the power-line
cord is plugged into an appropriate receptacle. Do not operate your power
supply without adequate cabinet ground connection.
1.2 Output Checkout
The following procedures check to ensure that the power supply develops its rated outputs and
properly responds to operation from the front panel.
1.2.1 Voltage Output Checkout
The following steps verify basic voltage functions without load.
1. Turn on the power supply.
2. Enable the outputs.
Press key to turn off the OFF annunciator and turn on the CV annunciator.
3. Set some different voltage values, then wait till the Meter mode to check if the
VFD displayed voltage value is the same as the set voltage value, and to check if
the VFD displayed current value is nearly zero.
4. Ensure that the voltage can be adjusted from zero to the full rated value.

10 USER’S GUIDE
Notice: if the voltage value ash, then the power supply is in Set mode, ‘‘Set
mode’’ means that the VFD display shows the setting output voltage and current.
Or the power supply is in Meter mode, ‘Meter mode” means that the VFD display
shows the actual output voltage and current and the ”Meter” annunciator is lit.
