Test Probe with Pulse Current Generator
for SECUSTAR FM+ and SECULIFE SB/SR

Applications

The test probe is suitable for testing
protective conductor connections at
electrical consumers with contact resistance
caused by, for example, oxidation. With
contact resistance of this sort, protective
conductor resistance might not comply with
the specified values during testing with the
minimum test current of 200 mA in
accordance with the standard.

Measurement results with considerably
lower impedance values can be obtained for
a short time by exposing these connections
to a higher current with a value of approx.
10 A,

because resistance-increasing deposits,
layers of oxidation and other contamination
can thus be eliminated for a given period of
time.
Use of “cleaning” by means of a current
surge should be taken into consideration in
the hazard evaluation for the object under
test.

Determine whether or not the test probe
complies with electrical safety requirements
and ambient conditions for use with your
test instrument. The test probe may only be
used for applications which are specified in
the operating instructions for your test
instrument. Make certain that the connector
cable, the test probe and the switch are in
flawless condition, e.g. no damage to
insulation, no interruptions in cables or
plugs etc.

Only perform the test with voltage-free protective
conductor connections to prevent the internal
fuse from blowing.

Connection

➭ Connect the test probe as follows:

Insert the test probe’s double plug into
sockets 1 and 2 such that the plug with
the white ring makes contact with socket
1, and insert the separate plug into the
test current output at the test instrument
(the socket between sockets 2 and 3).

Operation (single measurement)

➭

With the instrument in the “Manual Test”
mode, select resistance measurement R

➭ Press the start key at the test instrument

in order to initialize resistance measure­ment.

➭ Wait for at least 1 second.
➭ Contact the measuring point with the

test probe.

➭ Activate the current surge by briefly

pushing the slider switch on the test
probe into position B towards the tip of
the probe (spring force must be
overcome manually). The control LED
flashes up briefly. The short-term, high
current burns off any
resistance-increasing deposits.

Note!



!

Return the slide switch to normal position

after which test current in accordance

A,
with the standard flows via the test
probe for the performance of resistance
measurement.

A waiting period with a duration of 1
second between measurements is
required in order to reactivate the
pulse current generator and charge
the capacitor.

Operation During Test Sequences

The following test step order must be
adhered to during test sequences:

➭ Start protective conductor resistance

measurement.

➭ Wait for at least 1 second.
➭ Contact the measuring point with the

test probe.

➭ Briefly push the slide switch into position

B (see single measurement).

➭ Record the desired measured value.

A test sequence for use of the test probe in
combination with a SECUSTAR FM+ or
SECULIFE SB/SR test instrument is
included in scope of delivery on the CF card,
or can be downloaded from out website.
