OPERATION
3.1 Turning the Multimeter ON
Turn the switch to the appropriate function. All segments of the display will
light for a few seconds. The screen corresponding to the chosen function will
then appear. The multimeter is now ready for measurements.
3.2 Turning the Multimeter OFF
To turn the meter off manually, turn the switch to OFF. If left unused for
15 minutes, the meter will turn off automatically. At 14 minutes, five beeps
warn that the meter is about to be turned off. To turn back on, press any
button on the unit.
