V/Hz/dB – , Temperature, and A/Hz Measurements
5.1.1 Direct and Pulsating Voltage Measurement, V DC and V (DC+AC)
Note

Set the CL iP parameter to 0FF in the current clamp setup
menu. Otherwise all measured values are displayed in
amperes, corrected by the amount resulting from the
selected transformation ratio for an interconnected current
clamp sensor.

Ð In accordance with the voltage to be measured, turn the rotary
switch to V or 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 600 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 3 V measuring range immediately after it is switched on. As
soon as the MAN / AUTO key is pressed, and assuming the mea-
sured value is less than 300 mV, the multimeter is switched to the
mV measuring range.
