5.1.1 Direct Voltage, Pulsating Voltage and Crest Factor Measurement
– V DC, V (DC+AC) and CF
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. The clamp symbol is also displayed. Refer to
section 6.4, "Entering Parameters – SETUP Menu”,
regarding adjustment.
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 mea-
sured 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 (auto-ranging), the multime-
ter is always in the 6 V measuring range immediately after it’s swit-
ched on. As soon a the MAN / AUTO key is pressed, and assuming
the measured value is less than 600 mV, the instrument is swit-
ched to the 600 mV measuring range. Press the
 key in order to
switch to the 60 mV measuring range.
