The 100mV range is present only in MANUAL mode, by
.
In all cases, "OL" is displayed above 1050V and a beep sounds when the measurement
exceeds 600V.
The hazardous voltage symbol is displayed if "V" exceeds 60 V
DC
or 25 V

Waveform & trend
During an AC voltage measurement, the waveform of a signal at a frequency between 10 Hz and
600 Hz can be viewed using the
function.
As default, the GRAPH mode displays the trend curve of the quantity measured (default time base
1min28s) vs time.
5.1.5.
Procedure
1.
Press on the V function, then select the coupling according to your measurements:
AC, DC, AC+DC, LowZ (AC is default).
2.
Connect the black lead to the COM terminal and the red lead to V.
3.
Read the measurement indicated on the display unit; the graph of trend values
>1min 28s is displayed on the screen or selection of secondary measurement
Meas…/MEAS+
(4 display units max).
4.
It is possible to activate an MLI filter (
SETUP/Measurement/filter/yes
)
for
measurements on a variator: the cutoff frequency of the filter <300Hz.
5.
It is possible to display the
spec
ifications of
the range for metrology or a
RELative measurement.
6.
Surveillance of voltage by activation by
Meas…/SURV
