[4]  DESCRIPTION OF FUNCTIONS

4-1   Function Switch

Turn this switch to turn on and off the power and to select the
functions of "V    /V    /mV/     •     /Temp/

•    /A/mA/µA".

4-2   Auto Power Off

The Auto Power Off mode turns the meter off automatically to
extend battery life after approximately 17 minutes of no activities.
Activities are specified as:

1) Changing sw position or pressing a button.
2) Significant measuring data readings of around 10% of range.

To wake up the meter from Auto Power Off, press the SELECT
button momentarily or turn the rotary switch to the OFF position
and then turn back on again.
To disable the Auto Power Off feature, press the RANGE button
while turning the function switch on.

Note:

Always turn the function switch to the OFF position when the
meter is not in use.

4-3   Low Battery Indication

If the internal battery has been consumed and the internal battery
drops below approx. 7V, BATTERY mark is shown in the display.

4-4   Measurement Function Select
