Frequency Accuracy

This test verifies the frequency programming and measurement accuracy of the output voltage waveform.

Step Action

Normal Result

1

Turn off the UUT. Connect the Frequency Counter to the output as shown
above.

2

Turn on the UUT. Program output to RANGE 135 V,VOLT 20, FREQ 500

Output at 80 Vrms, CV annunciator on, Current near
0

3

Record the output frequency reading from counter

Readings are within specified limits

DC Voltage Programming and Readback Accuracy

This test verifies the DC voltage programming and front panel readback functions are within specifications.

Step Action

Normal Result

1

Turn off the UUT. Connect the DMM directly to the output terminals. The DMM neg-
ative lead is connected to the Neutral output terminal.

2

Turn on UUT. Program output to RANGE 135 V, VOLT 0, OUTP:COUP DC, OFFSET 190

Output at 190 VDC, output current near 0

3

Record DC voltage at DMM and readback from front panel display.

Readings within specified DC voltage pro-
gramming and readback limits.

4

Program output to RANGE 270 V, VOLT 0, OUTP:COUP DC, OFFSET 380

Output at 380 VDC, output current near 0

5

Record DC voltage at DMM and readback from front panel display.

Readings within specified DC voltage pro-
gramming and readback limits.

DC Current Measurement Accuracy

This test verifies that the DC voltage programming and front-panel readback functions are within specifications.

Step Action

Normal Result

1

Turn off the UUT and connect the appropriate load resistor, DC current shunt and
DMM as shown in the diagram above.

2

Turn on UUT. Program output voltage to RANGE 135 V, VOLT 0, OUTP:COUP DC,
OFFSET 64.

Output voltage at 64 VDC, CV annunciator on,
output current near:
4 A for AC6801A
8 A for AC6802A
16 A for AC6803A
32 A for AC6804A

3

Record DVM reading and calculate current.

Readings within specified DC current readback
limits.
