3.8 Functional Test
CAUTION: Work carefully when performing these tests - hazardous voltages are
present on the input and output during this test.
Refer to Figure 3-7 for the test set up. For –LZ and –AV option units, the resistor values
need to be adjusted as follows:
Model Voltage Range Resistor Current (A
RMS
)
2001RP 150 11.2
Ω 13.4
300 45.0
Ω 6.7
2001RP-AV 115 6.6
Ω 17.4
230 (if available) 26.4
Ω 8.7
2001RP-LZ 135 9.1
Ω 14.8
270 36.5
Ω 7.4
1. Connect an oscilloscope, voltmeter and/or distortion analyzer to the AC source output at
the rear panel output terminal.
2. Connect the AC power input voltage connections to the AC source input terminals.
Connect the sense input to the adjacent power pin on the rear panel connector. Turn on
the power switch located at the rear panel.
3. Verify that the front panel LCD display reads out the initial start up voltage and frequency.
4. Select the low voltage range. Set the frequency to 60 Hz with the right shuttle (400 Hz for
the –AV option). Select the current function with the Frequency/Current selector. Set the
current limit to the maximum value using the right shuttle. Set the output voltage to 150V
(135V for the -LZ option, 115 V for the –AV option.) with the left shuttle.
5. Enable the output by pressing the output “on/off” button in the top right of the front panel.
The green LED above the button will illuminate when the output is on. The output should
be a clean 150V (135V for the -LZ option, 115 V for the –AV option) AC sinewave having
less than 0.5 % distortion. (1 % for -AV option)
6. Apply full load (refer to table on Figure 3-7) to the output of the source and verify the
output remains within 0.05 % of the initial 150V (135V for the -LZ option, 115 V for the –
AV option) value or 75 mV. The output should still be clean and the distortion should still
be less than 0.5 % at 60 Hz. (less than 1.0 % at 400 Hz for the –AV option).
7. Using the right shuttle set the output current limit value to 6 amps. If the unit is configured
for Constant Current mode (factory default), the system should go into current limit and
reduce the output voltage. This may create additional distortion on the output voltage. If
the unit is configured for Constant Voltage mode, an error message will appear on the
display (err. -300) that indicates an output fault condition and the output will go off.
Return the current value to the maximum current and disconnect the load.
8. Repeat steps 4 through 7 but set the output for the following: Hi voltage range and the
current limit to maximum value. The load value is different for the 300 V setting. (270 V
for the LZ option, 230 V for the –AV option.) Refer to the table above for the relevant
resistor values. For units that are factory configured with a single voltage range, these
steps do not have to be repeated.
In the 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.
