The RANGE button converts this auto-ranging meter to a manual ranging meter. This allows the user to control the desired reading that is dependent on the application. It enables converting an OL, or over limit, reading on the display to a readable number. The RANGE button can be used with any of the settings noted in the red circles shown here. It is quick and easy to make the change, like getting two meters in one. An auto-ranging meter can be switched to manual-ranging, but a meter designed for manual-ranging only cannot be converted to an auto-ranging meter.
