Note: In AUTO-READ mode, the meter will display the measurement as it stabilizes and lock and hold the
measurement when it is stable. AR and unit of measure will blink until the reading is stable. When the
reading is stable it is held on the screen and AR is lit. Press
In Continuous read mode, the meter will continuously measure and update the display. The unit of
measure will flash. When the reading is stable, "READY" will appear. This read type is useful when
performing an experiment that requires continuous measurements to be taken, regardless of the
measurement stability.
