Details
This command determines how the range is selected.
When this command is set to off, you must set the range. If you do not set the range, the instrument
remains at the range that was selected by autorange.
When this command is set to on, the instrument uses the signal to determine the most sensitive
range on which to perform the measurement. The instrument sets the range when a measurement is
requested. To set the range, the instrument makes a measurement to determine the range before
making the final measurement, which can result in slower reading times. Turn autorange off and set a
specific range to increase measure time.
If a range is manually selected through the front panel or a remote command, this command is
automatically set to off.
Example
dmm.measure.func = dmm.FUNC_ACV_PERIOD
dmm.measure.threshold.autorange = dmm.ON
