1.1 Voltage
The purpose of this study is to measure the direct and the
alternating voltage: in the AC range only the alternating
voltage is displayed, the direct voltage and the rms value (DC
+ AC) are displayed in the DC range.
Measuring method
Connect the wires to be measured and the shield of the cable.
Select the
Voltage mode and press SEL . The measurement is
then started automatically. The results of the alternating and
direct voltage are displayed numerically in volts and the
frequency in Hz.
With
F1 , the min / max values can be switched on or off for
easier assessment. Under F2 Probe the measurement points
can be selected from the differential voltage measured
between two cores of a pair of conductors (A-B) and the
common-mode voltage measured between a pair of
conductors and the ground (A-GND, B-GND). With
F3 , the
measuring ranges can be switched between DC (DC voltage)
and AC (AC voltage) and AC TP (AC voltage with low-pass
filter> 200 Hz). Under
F4 Term, the input resistance is reduced
from 10 MW to 120 kW to measure the actual voltage.
Safety note:
The measured voltage must not exceed the value of 600 V
for phase to ground or phase to phase.
