Basic Checks or Self-Tests
TM-XDOP-01XN
2–13
Basic Checks or Self-Tests
The functional test procedures described in this section include power-on and
front panel function checks as well as voltage and current mode operation checks.
Equipment Required
•
Digital Voltmeter (DVM) rated better than 0.05% accuracy.
•
DC shunt 1mV/A (
±
0.25%) with connecting wire. The recommended current
ratings for the DC shunt and the wire must be at least 10% more than the
output current of the power supply.
Display Test
To ensure that the display is working properly:
1. Turn the power switch ON.
2. Observe the display panel.
Every pixel should illuminate for 2 seconds as part of the power-on self-test.
If you need to rerun the test:
1. Turn the power switch OFF.
2. Wait until the pixels fade to black.
Some residual charge may remain in the capacitors after the power is OFF.
Waiting for the display to fade ensures that the capacitors have sufficiently
discharged their power to reset the power supply.
3. Turn the power switch ON.
4. Observe the display panel.
If you observe or suspect that one or more of the display pixels is malfunctioning,
contact the manufacturer.
Power ON Check
To complete the power on check:
1. Ensure that the AC power switch is OFF.
2. Connect the unit to an AC outlet.
WARNING
The factory setting for Power ON is 0V and 0A with the output OFF. These settings can be
customized by end users. If you suspect that the power supply has been used by someone
else since it was received from the factory, be prepared for the unit to power ON with a
live DC output.
