5.1.1 Direct and Pulsating Voltage Measurement, V DC and V (DC+AC)
➭ Set the CL iP parameter to 0FF in the current clip setup menu. 

Otherwise all measured values are displayed in amperes, 
corrected by the amount resulting from the selected transfor-
mation ratio for an interconnected clip-on current sensor.

➭ In accordance with the voltage to be measured, turn the rotary 

switch to V

  or V .

➭ Connect the measurement cables as shown. 

The “

⊥” connector jack should be grounded.

Note



An intermittent acoustic signal warns the operator if the 
measured value exceeds the upper range limit in the 1000 V 
range.

Make sure that a current measuring range (“A”) has not been 
activated when the multimeter is connected for voltage 
measurement! If the fuse’s blowing limits are exceeded as a 
result of operator error, both the operator and the instrument are 
in danger!

With the rotary switch in the V position, the multimeter is always in 
the 1 V measuring range immediately after it is switched on. As 
soon a the MAN / AUTO key is pressed, and assuming the 
measured value is less than 280 mV, the multimeter is switched to 
the mV measuring range.
