Appendix B Verification and Calibration

4With the electronic load in CV mode, set it for the output’s full- scale voltage. The CC annunciator on the front panel must be on. If it is not, adjust the load so that the voltage drops slightly.

5Divide the voltage drop (DVM reading) across the current monitoring resistor by its resistance to convert to amps and record this value (Iout).

6Short the electronic load. Divide the voltage drop (DVM reading) across the current shunt by its resistance to convert to amps and record this value (Iout). The difference in the current readings in steps 4 and 5 is the load effect, which should not exceed the value listed in the test record card for the appropriate model under CC Load Effect.

CC Source Effect

Test category = performance

This test measures the change in output current that results from a change in AC line voltage from the minimum to maximum value within the line voltage specifications.

1Turn off the power supply and connect the ac power line through a variable voltage transformer or AC source.

2Connect the current shunt, DVM, and electronic load as shown in figure B. Connect the DVM directly across the current shunt. Set the variable voltage transformer to nominal line voltage.

3To ensure that the values read during this test are not the instantaneous measurement of the AC peaks of the output current ripple, several DC measurements should be made and averaged. If you are using an Agilent 3458A, you can set up the voltmeter to do this automatically. From the instrument’s front panel, program 100 power line cycles per measurement. Press NPLC 100 ENTER.

4Turn on the power supply and program the output current to its full-scale value and the output voltage to its maximum programmable value (Vmax).

5With the electronic load in CV mode, set it for the output’s full- scale voltage. The CC annunciator on the front panel must be on. If it is not, adjust the load so that the voltage drops slightly.

6Adjust the transformer to the lowest rated line voltage (85 VAC for 100/120 nominal line; 170 VAC for 200/240 nominal line).

7Divide the voltage drop (DVM reading) across the current monitoring resistor by its resistance to convert to amps and record this value (Iout).

8Adjust the transformer to the highest rated line voltage (132 VAC for 100/120 nominal line; 265 VAC for 200/240 nominal line).

9Divide the voltage drop (DVM reading) across the current shunt by its resistance to convert to amps and record this value (Iout). The difference between the DVM reading in steps 6 and 8 is the source effect, which should not exceed the value listed in the test record card for the appropriate model under CC Source Effect.
