5.3 Auto/Manual Range Mode
In Auto range mode, the meter automatically selects the most appropriate measurement scale. In
Manual range mode, the desired range (scale) is set manually.
Auto range mode is the default mode of operation. When a new function is selected with the
function switch, the starting mode is Auto range and the indicator is displayed.
To enter Manual range mode, press the
repeatedly until the desired range is displayed.
To enter Auto range mode, press and hold the
