General remarks on measuring
Choose a function according to the measured extent and turn the selector switch
accordingly. If the voltage of the battery is lower than the normal operating
voltage, this symbol
The symbol next to the input jack shows that the input voltage or input
current should be lower than the maximum value listed on the meter – to protect
the inner circuit. When connecting the measurement lines, please connect the
earth lead (COM) first and only then the measurement lines. For loosening the
measurement lines, remove the lines first and afterwards the earth lead (COM).

Automatic shutdown

After 14 minutes of disuse, the device announces the automatic shutdown with
five short sounds. After another minute, the device shuts down automatically,
signalised through a long signal at the end. After an automatic shutdown, to
turn on the device again, you can turn the switch to any function. To deactivate
the automatic shutdown, press "HOLD" button while you turn on the device.
