User and Programming Manual - Rev P California Instruments3.6. Output Voltage RangesThe AC power source has two standard output voltage ranges 0-135V and 0-270V. Theoperator may switch from one range to the other at will with no special precautions except toremember that the output voltage will go to zero voltage whenever a range change takesplace.Note: The output changes to the other socket on front panel with a range change.3.7. Functional TestCAUTION: Work carefully when performing these tests - hazardous voltages arepresent on the input and output during this test.Refer to Figure 3-3 for the test set up.1. Connect an oscilloscope, voltmeter and/or distortion analyzer to the AC source output atthe 135 Volt output terminal.2. Connect the AC power input voltage connections to the AC source input terminals. Turnon the power switch located at the rear panel.3. Verify that the front panel LED SEGMENT display reads out the initial start up voltageand frequency.4. Select the low voltage range. Set the frequency to 60 Hz with the right shuttle. Select thecurrent function with the Frequency/Current selector. Set the current limit to themaximum value using the right shuttle. Set the output voltage to 135V with the leftshuttle.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 outputshould be a clean 135 volt AC sinewave having less than 1% distortion.6. Apply full load (refer to table on Figure 3-3) to the output of the source and verify theoutput remains within 2% of the initial 135 volt value. The output should still be cleanand the distortion should still be less than 1% at 60 Hz.7. Using the right shuttle set the output current limit value to 6 amps. The system shouldgo into current limit and give an error message on the display (err. -300) that indicatesan output fault condition and the output will go off. Return the current value to themaximum current and disconnect the load.8. Repeat steps 4 through 7 but set the output for the following: Hi voltage range and thecurrent limit to maximum value. The output load should be connected to the Hi rangeoutput connector. The load value is shown in Figure 3-3, for the 270 volt output.Note: Output connectors must be changed when changing voltage ranges unlessthe rear panel output terminals are used.October 2005 RP Series10 |
