• Configuring a Channel to Measure Temperature (RTDs) (Figure 2-9)
• Configuring a Channel Off (Figure 2-10)
The instrument is protected from channel configuration errors. For example, accidentally
applying 300V ac to a channel configured for resistance will not damage the instrument.
Configuring a Channel to Measure DC Volts
Perform the procedure in Figure 2-4 to configure a channel for measuring dc 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 dc for channels 0, 1, 11, and
150V dc for channels 2 to 10, and 12 to 20.
90.000 mV Range. Not used in Auto (autoranging).

Selecting the DC Volts Mode. Press the FUNC
key to access the SET FUNC (Set Function)
menu. Press the up/down arrow keys until V DC
(volts dc) 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 (1.0)
multiplier indicates a reading in volts dc; the m
multiplier (0.001) indicates a reading in millivolts
dc. A 900.00 mV range is available by computer
interface and may appear in the display if this
was previously selected.
In Auto (autoranging), the instrument chooses the
scale for the best measurement resolution.
When the scales are changed, the scan is
momentarily slowed.
* Depends on temperature scale.
** Channels 0, 1, and 11.
*** Channels 2 to 10, and 12 to 20.
