Measuring Adapter BENNING MA 2-16
2
If in doubt, i. e. in cases where the results of a measurement
are close to the permissible limit value, measure the
protective conductor resistance of the adapter on the PE
connection of its CEE socket and subtract this value from
the measured value of the system.
To measure the protective conductor current with the
differential current method set the measurement type
switch to
ΔI
(Differential Current). In the case of a 3-
phase differential current measurement, the resulting
differential current is transmitted to the tester and
recorded as protective conductor current on the
protective conductor.
To measure the protective conductor current directly set
the measurement type switch to
I
direkt
Before carrying out the functional test and all tests in
which the test sample has to be supplied with supply
voltage and put into operation, it is imperative that there
are no short circuits in the test sample within the phases
L1, L2, L3 and the neutral conductor N! Non-
observance could result in the
BENNING MA 2-16
measuring adapter, or even your test sample, being
damaged or destroyed!
The values for the power and current consumption of
the test sample cannot be measured with the
BENNING MA 2-16
adapter within the scope of the
functional test. The values displayed relate to the power
consumption of the
BENNING MA 2-16
adapter.
Attention!
Sequence of the test
–
Problem starting currents
Starting the test
To put your test sample into operation it is imperative
that you first start the test of your tester (orange lamp
on the
BENNING MA 2-16
illuminated) and then
switch on your test sample!
Ending the test
It is imperative that you first switch off the test
sample and then end the test on your tester.
In the case of extreme starting currents of your test
sample or in the case of inductances in the circuit,
non-observance of this sequence could result in the
BENNING MA 2-16
adapter being damaged or
destroyed!
Attention!
Short circuit test of the test sample
A short circuit of two or all three phases in the test
sample cannot be determined by the tester before
the differential current test! In such a case the
BENNING MA 2-16
adapter can be severely
damaged by the arsing current surge when carrying
out this test!
For this reason test that there is no short circuit
between the phases of the test sample, e. g. with
a continuity tester, before connecting a device
to the BENNING MA 2-16!
Attention!
Correct phase connection of the test sample
Take care, especially after a repair of three-phase
devices or reconnection of a CEE plug, that the
phases are connected in the correct sequence.
Attention!
Interruption of the protective devices
– max.
current consumption
As soon as the orange signal lamp on the
BENNING MA 2-16
lights up, the connections of the
supplying mains socket are unprotected or a
different type of protective element is connected to
the test/mains socket of the measuring adapter.
Take care that only devices designed for a three-
phase current with a max. current consumption of
3 x 16 A (AC-1) are connected to this socket.
