Dc Current Measurement; Ac Voltage Measurement - Würth AM 600 Traduction Des Instructions De Service D'origine

To avoid discharging and/or inaccurate measured
values, do not perform current measurements on
high voltage cabling (> 600 V).
AC current measurement
Check that the test leads are pulled out
of the measuring sockets.
Set the function switch to the A~ range.
■
Encircle the cable to be measured with the clamp
■
jaws [1].
The clamp must be completely closed.
Read off the measured value.
■
3 Using the "True RMS" function, zeroing devia-
tions of up to 30 digits occur. These do not have
any effect on the measured value.

DC current measurement

The test leads must be pulled out of the
measurement sockets.
Set the function switch to the A= range.
■
Encircle the cable to be measured with the clamp
■
jaws [1].
The clamp must be completely closed.
Note the polarity signs!
■
Read off the measured value.
■
If necessary, zero prior to measuring.
■
To do this open and close the clamp jaws [1]
■
without a cable several times.
Wait until the value in the display [8] has
■
stabilised.
Press button SEL [11].
■
The value indicated changes to 0.00 and ZERO
■
appears in the display [8].
3 It is possible that the last figure, oscillates a little;
but this is not an error.
DC current measurement
The maximum input voltage in the range V DC is 600
V DC. To avoid hazards due to electric shocks and/
or damage to the device, to not perform any meas-
urements at voltages greater than 600 V DC.
Set the function switch to the V range.
■
Press button SEL [11] to select DC.
■
Plug the black and red test leads into the in-
■
puts COM [7] and INPUT [6].
Position the test leads on the circuit to be meas-
■
ured and read off the value.

AC voltage measurement

The maximum input voltage in the range V AC is 600
V RMS. To avoid hazards due to electric shocks
and/or damage to the device, to not perform any
measurements at voltages greater than 600 V RMS.
Set the function switch to the V range.
■
Press button SEL [11] to select AC.
■
Plug the black and red test leads into the in-
■
puts COM [7] and INPUT [6].
Position the test leads on the circuit to be meas-
■
ured and read off the value.
Resistance / continuity / diode meas-
urements
Before any resistance measurement, ensure that the
circuit to be measured is completely current-free and
all capacitors are discharged.
Set the function switch to the Ω/
Press button SEL [11] to switch between resist-
■
ance, continuity and diode measurement.
Plug the black and red test leads into the in-
■
puts COM [7] and INPUT [6].
Position the test leads on the circuit to be meas-
■
ured and read off the value.
The continuity test is suitable for
detecting short and open circuit
conditions.
Auto Power OFF
3 To preserve the batteries, the device switches off
automatically after approximately 30 minutes.
If the device is in standby mode, pressing the SEL
■
[11] button returns it to normal measuring mode.
True RMS
When measuring non-sinusoidal waveforms, smaller
measurement errors occur using the True RMS
function than when using conventional measuring
methods.
Sinusoidal and non-sinusoidal signals can be meas-
ured exactly using the True RMS function.
During alternating current and alternating voltage
measurement, zeroing differences of 1 - 50 digits
can occur.
The measurement result is not influenced by this.
To maximise the precision of the device, the alter-
nating voltage should be > 13 mV and alternating
current > 1.3 A.
