V/Hz, Ω, Temperature, and A/Hz Measurements
5.1.1 Direct and Pulsating Voltage Measurement, V DC and V (DC+AC)
Note

The following must be observed for all multimeters except for the
METRAHIT E
BASE:
Set the CL iP parameter to 0FF in the current clamp setup
menu. Otherwise all measured values are displayed in
amperes, and are corrected by the amount resulting from
the selected transformation ratio for an interconnected cur-
rent clamp 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 meas-
ured 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 measure-
ment! If the fuse’s blowing limits are exceeded as a result of oper-
ator error, both the operator and the instrument are in danger!
With the rotary switch in the V position, the multimeter is always
set to the 6 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 600 mV, the multimeter is switched to
the mV measuring range.
