Würth MM 600 TRMS Traducción Del Manual De Instrucciones De Servicio Original página 16

Before measuring make certain that all other test
■
leads are removed.
The red test lead can be used for single phase
■
testing by pressing the M button [8].
3 The display [1] flashes and a bleep is heard.
This measurement is not suitable for
the detection of dangerous mains
voltages.
Even if the display [1] does not flash
during testing or measurement and no
signal beep is emitted, a dangerously
high voltage (> 33 V AC or 70 V DC)
may still be present.
¾ Before touching live parts, check
for the presence of dangerous
voltages by means of direct,
double-pole contact measurement
of the alternating current area.
Cable break detector
The cable break detector is for the non-contact
detection of cable breaks in unexposed, live cables.
Set the selector switch to CABLE BREAK DETECT.
■
3 If the sensor at the top end of the multimeter is
moved along a live cable (100 - 300 V AC) star-
ting from the feed-in point, while keeping the M
button [8] pressed, the display [1] flashes and
a beep is emitted before the break point.
The non-contact cable break detection
function is not suitable for the detec-
tion of dangerous mains voltages.
The non-contact sensor can only detect
voltages created by power sources
with sufficiently strong electric fields
(mains network, > 100 V AC).
Attention!
This measurement is not suitable for the detection
of dangerous mains voltages.

DANGER!
DANGER!
Even if the display [1] does not flash during
■
testing or measurement and no signal beep is
emitted, a dangerously high voltage (> 33 V AC
or 70 V DC) may still be present.
Before touching live parts, check for the presence
■
of dangerous voltages by means of direct,
double-pole contact measurement of the alterna-
ting current area.
In weaker electric fields, the device may not
■
recognise the applied voltage and therefore not
be cable to correctly locate the cable break.
If the device does not detect any voltage, this
■
may be caused, amongst others, by the following
factors:
• Shielded cables/wires
• Thickness and type of insulation
• Distance to the voltage source
In case of voltages exceeding 30 V,
proceed with care as there is a risk of
electric shock.
Direct current measurement
Set the selector switch measurement range to
■
A
.
~
Set M button [8] to DC.
■
Connect the black measuring lead to the COM so-
■
cket [5] and the red measuring lead to the right
socket (up to max. 250 mA).
Attention!
For measurements above 250 mA, the 10 A
socket [7]must be used.
Connect the measuring leads to the test object.
■
3 The multimeter automatically searches for the
most favourable measurement range.
Read the measurement result from the dis-
■
play [1].
Attention!
To protect the device against overheating, allow a
pause of 30 minutes for cooling after measuring
for a period of no more than 30 seconds.
