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 Ckey.

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.

Selecting the AC Volts Mode. Press the FUNC key to access the SET FUNC (Set Function) menu. Press the up/down arrow keys until VAC (Volts AC) is displayed, then press the ENTER key.

Selecting the Measurement Scale. Select a fixed scale or Auto (autoranging). A fixed scale indicates an upper measurement limit. For 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.
