3.8.3Constant Voltage Check

1.Turn on the output by pressing the OUT pushbutton so the OUT LED illuminates.

2.Observe the power supply VOLT display and rotate the Voltage encoder. Ensure that the Output Voltage varies while the VOLT encoder is rotated. The minimum control range is from zero to the maximum rated output for the power supply model.

Compare the DVM reading with the front panel VOLT display to verify the accuracy of the VOLT display. Ensure that the front panel VOLT LED is On.

3.Turn Off the front panel AC power switch.

3.8.4Constant Current Check

1.Ensure that the front panel AC power switch is at the Off position and the DVM connected to the output terminals shows zero voltage.

2.Connect a DC shunt across the output terminals. Ensure that the shunt and the wire current ratings are higher than the power supply rating. Connect a DVM to the shunt.

3.Turn the front panel AC power switch to the On position,

4.Turn On the output by pressing OUT pushbutton so the OUT LED illuminates.

5.Observe the power supply CURRENT display and rotate the CURRENT encoder. Ensure that the Output Current varies while the CURRENT encoder is rotated. The minimum control range is from zero to the maximum rated output for the power supply model.

Compare the DVM reading with the front panel CURRENT display to verify the accuracy of the CURRENT display. Ensure that the front panel CURRENT LED is On.

6.Turn Off the front panel AC power switch.

7.Remove the shunt from the power supply output terminals.

3.8.5OVP Check

Refer to Section 5.3 for explanation of the OVP function prior to performing the procedure below.

1.Turn the front panel AC power switch to the On position and turn on the output by pressing OUT pushbutton.

2.Using the VOLT encoder, adjust the Output Voltage to approx. 10% of the unit voltage rating.

3.Momentarily press the OVP/UVL button so that the CURRENT display shows “OUP”. The VOLTAGE display will show the last setting of the OVP level.

4.Rotate the VOLT encoder CCW to adjust the OVP setting to 50% of the unit voltage rating.

5.Wait a few seconds until the VOLT display returns to show the Output Voltage.

6.Adjust the Output Voltage toward its maximum and check that the Output Voltage cannot be increased more than the OVP setting.

7.Adjust OVP limit to the maximum by repeating Step 3 and rotating the VOLT encoder CW.

3.8.6UVL Check

Refer to Section 5.4 for explanation of the UVL function prior to performing the procedure below.

1.Press the OVP/UVL button TWICE so that the CURRENT display shows “UUL”. The VOLTAGE display will show the last setting of the UVL level.

2.Rotate the VOLT encoder to adjust the UVL level to approx. 10% of the unit voltage rating.

3.Wait a few seconds until the VOLT display returns to show the output voltage.

4.Adjust the output voltage toward its minimum and check that the output voltage cannot be decreased below the UVL setting.

5.Adjust the UVL limit to the minimum by repeating step 1 and rotating the VOLT encoder CCW.
