Measurement Ranges
Some models have two voltage and current measurement ranges.
Refer to Chapter 1, “Model Differences” for model-specific
information. Selecting a lower measurement range provides greater
measurement accuracy, provided that the measurement does not
exceed the range. The commands that control the ranges are:
Front Panel:
SCPI Command:
Select
Measure\Range
.
Select the desired voltage or
current range and press Select.
SENS:CURR:RANG 0.1, (@1)
SENS:VOLT:RANG 5, (@1)
When the range is set to MAX, the maximum current that can be
measured is the maximum rating of the unit. Two examples of
programming measurement ranges are:
0.1 A range
To select, program values
≤
0.1A.
3 A range
To select, program values > 0.1A and
≤
3A.

Self-Test
A
power-on
self-test occurs automatically when you turn on the power
system. This test assures you that the instrument is operational. If
the self-test is successful, the power system will continue to operate
normally. If the self-test fails, the Err annunciator comes on. Press
the Error key to display the list of errors on the front panel. Refer to
Appendix D for further information.
