4. Application description
DC VOLTAGE MEASUREMENT
Set the selector switch to measurement range V=.
Insert the black test lead into the 'COM' socket and the red test lead into the right-
hand socket. Using the test probes, touch the test points of the test object.
The multimeter automatically searches for the most suitable measurement range.
Read measurement value on the display.
AC VOLTAGE MEASUREMENT (contact or non-contact techniques)
Set the selector switch to measurement range V~.
Insert the black test lead into the 'COM' socket and the red test lead into the right-
hand socket. Using the test probes, touch the test points of the test object.
The multimeter automatically searches for the most suitable measurement range.
Read measurement value on the display.
When the top edge of the multimeter is held up to a live conductor (100 – 300 V
AC) while the M-button is held pressed down, the display flashes and an acoustic
signal is emitted. The same happens during a single-pole phase test using the red
test lead.
If, when carrying out a single-pole phase test (via contact or non-contact), the
display does not flash and no acoustic signal is emitted, a dangerously high voltage
(>33 V AC or 70 V DC) may nevertheless be present. Therefore, carry out a test
before and after use at a known, live source, which corresponds to the rated AC
voltage range of the product, to ensure that the instrument is functioning properly.
The non-contact sensor detects voltage generated by sufficiently strong electric
fields from power sources (grids, >100 V AC). If the field strength is low, the
instrument may not detect applied voltage. If the instrument does not detect
existing voltage, this can be due to the following factors, amongst other things:
-
Shielded wires/cables
-
Thickness and type of insulation
-
Distance from the voltage source
-
Fully-isolated consumer devices that prevent effective earthing.
-
Connectors in flush-type sockets / differences in socket design.
Exercise caution at voltages above 30V, as there is a risk of electric shock.
The "NON CONTACT VOLTAGE DETECT" function is only for "Cable break
detector".
The cable break detector is intended for the non-contact localization of cable
breaks on live lines.
