9 Voltage Measurement

According to the voltage to be measured, set the function

selector switch (6) to V AC or V DC. Connect the test leads as

shown. The „ “ socket should be connected to the lowest

potential ground available. In V AC mode, the main display

always shows voltage and the sub-display shows frequency.

Note

The 660 mV measuring ranges can only be selected manually

with the „AUTO/MAN“ (4) pushbutton.

Caution

Ensure that the current

measuring range („mA“ or

„A“) is not selected during

voltage measurement! If

the cut-out rating of the

fuses is exceeded due to

improper operation, a

dangerous situation may

occur!
