3 Configuring for Measurements
Configuring for DC or Resistance Measurements
This section describes how to configure the multimeter for making DC voltage, DC
current, and 2-wire or 4-wire resistance (ohms) measurements.
DC voltage
The multimeter measures DC voltage on any of five ranges.
DC voltage range and its full scale reading (which also shows the maximum
number of digits for the range).
the input resistance for each range. (Resolution is a function of the specified
integration time: refer to
information.)
voltage measurements. In the power-on/PRESET NORM states. DC voltage
measurements are selected. You can also specify DC voltage measurements using
the DCV command. For example, to specify DC voltage measurements on the 1 V
range, send:
OUTPUT 722;"DCV 1"
