CONT = Continuous
AUTO = AUTO-READ™
Note: In AUTO-READ mode, the meter will display the measurement as it stabilizes and lock and hold the

measure will flash. When the reading has been 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.
