5.2.1 Direct Voltage Measurement, V DC
Note

Set the CL iP parameter to 0FF in the current clamp setup
menu. Otherwise all measured values are displayed in mA,
corrected by the amount resulting from the selected transfor-
mation ratio for an interconnected current clamp sensor.

Ð In accordance with the voltage to be measured, turn the rotary
switch to V .
Ð 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
300 V range.
Make sure that a current measuring range (“A”) has not been acti-
vated, 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 310 mV, the multimeter is switched to
the mV measuring range.
