A group of arrows display when a measurement is out of range for the scale selected:
•
Arrows pointing UP—measurement over maximum range
•
Arrows pointing DOWN—measurement under minimum range
Voltage measurements also display arrows in place of live values when the voltage exceeds the
input rating of the meter.
