3.9 Functional Test
CAUTION: Work carefully when performing these tests, hazardous voltages
are present on the input and output during this test.
Refer to Figure 3-8 for the test set up.
1. Connect an oscilloscope, voltmeter and/or distortion analyzer to the AC source output at the
output terminal block (TB2).
2. With the AC mains verified as being off, apply the correct three phase AC power input
voltage connections to the AC source input terminals barrier (TB1). Apply the AC mains
power and turn on the main circuit breaker on the AC source front panel.
3. Verify the front panel LCD display lights up with the initial start up screen showing the unit ID
and serial number. A self check routine screen with follow and finally the system will display
the main “Menu 1” screen with the cursor highlighting the “Program” selection.
4. Press “ENTER” and the unit will display the Program selection screen. Set the following
output parameters: output voltage = 150 volts, frequency = 60 Hz, voltage range = 150 volts,
and current limit = 20.0 amps (3001iX) or 33.3 amps (5001iX). Press “ENTER”.
5. Enable the output by pressing the output “on/off” button below the front panel display screen.
The green LED next to the button will light green when the output is on. The output should
be a clean 150 volt AC sinewave having less than 1% distortion.
6. Apply full load to the output of the source and verify the output remains within 2% of the initial
150 volt value. The output should still be clean and the distortion should still be less than 1%
at 60 Hz.
7. Using the PROGRAM screen set the output current limit value to 17 amps. The system
should go into current limit. Return the current value to 20.0 amps (3001iX) or 33.3 amps
(5001iX) and press the output on/off button to turn the output off. Disconnect the load.
8. Repeat steps 4 through 7 but set the output for the following: output voltage = 300 volts,
output range = 300 volts, current limit = 10.0 amps (3001iX) or 16.7 amps (5001iX). For step
7, the current limit value can be set to 8 amps.
In the unlikely event the power source does not pass the functional test, refer to the
calibration procedure in Section 6 or call California Instrument‟s customer satisfaction
department for further assistance.
