Configuring a Channel to Measure AC Volts

Perform the procedure in Figure 2-5 to configure a channel for measuring ac volts. In
preparation, the instrument must be in the inactive mode (not scanning or monitoring)
and the desired channel must be selected (see Figure 2-3). To exit at any time (changes
not saved), press the C key.
Restrictions
Maximum Input. The maximum voltage inputs are 300V ac (rms) for channels 0, 1, 11,
and 150V ac (rms) for channels 2 to 10, and 12 to 20.
Frequency. The frequency range for maximum voltage inputs is 20 Hz to 100 Hz. Refer
to Appendix A for derated voltage inputs for frequencies between 100 Hz and 100 kHz.

fixed scale or Auto (autoranging). A fixed scale
indicates an upper measurement limit.
example, the 30.000 V scale measures 30 volts
or less. Measurements beyond the scale limit will
cause an OL (overload) display. The x1 (unity or
x 1) multiplier indicates a reading in volts ac; the
m (milli or x .001) multiplier indicates a reading in
millivolts ac.
In Auto (autoranging), the instrument chooses the
scale for the best measurement resolution.
When the scales are changed, the scan is
momentarily slowed.
