V/Hz, Ω, Temperature, and A/Hz Measurements
5.1.1 Direct and Pulsating Voltage Measurement, V DC and V (DC+AC)
Note
Only to observe for METRAHIT⏐TECH: Set the CL iP parameter
to 0FF in the current clip setup menu. Otherwise all meas-
ured values are displayed in amperes, and are corrected by
the amount resulting from the selected transformation 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 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 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 90 mV, the multimeter is switched to
the mV measuring range.
