Selecting The Range - Keysight Technologies U1231A Guia Del Usuario

Introduction 1

Selecting the range

The multimeter's selected range is always displayed above the right-hand end of
the bar graph, as the range indicator.
Pressing switches the multimeter between manual and autoranging. It also
cycles through the available multimeter ranges when manual ranging is enabled.
Autoranging is convenient because the multimeter automatically selects an
appropriate range for sensing and displaying each measurement. However,
manual ranging results in better performance, since the multimeter does not have
to determine which range to use for each measurement.
The range is fixed for diode tests, temperature, VZ , and AC/DC mV

measurements.
In autorange, the multimeter selects the lowest range to display the highest
available precision (resolution) for the input signal. If manual range is already
enabled, press for more than 1 second to enter the autoranging mode.
If autoranging is enabled, press to enter the manual range mode.
Each additional press of sets the multimeter to the next higher range, unless
it is already in the highest range, at which point the range switches to the lowest
range.
