Auto Range Modes

Last Modified: October 21, 2021

When specifying a range for a voltage or current measurement, you can select Auto or Auto once to measure a signal when you do not know which range to select. The digital multimeter (DMM) takes a series of measurements and adjusts the range until the measurement falls within the smallest range appropriate for that measurement.
  • Auto—Takes a reading before each measurement to select the smallest appropriate range.
  • Auto once—The first point measured determines the range for the rest of the measurements.
