OPERATING INSTRUcTIONS
MAGNETIc fIELD TESTER MS-440
ITEM NO.: 12 34 57
INTENDED USE
The magnetic field tester is intended for detecting constant and alternating magnetic fields. The
Tester is ideal for testing the functioning of inductors carrying currents, such as relays, magnetic
valves, etc. The tester works with any contacts and, therefore, it is normally not necessary to
open the casing. If a magnet field is detected, the probe will light up and an acoustic signal will
sound. A permanent test magnet, to test the functioning, is included in the delivery.
Additionally, the tester has an integrated LED lamp.
The magnetic field tester is powered by two micro-batteries. Do not use any other power
source.
For safety and approval purposes (CE), you must not rebuild and/or modify this product. If you
use the product for purposes other than those described above, the product may be damaged.
In addition, improper use can cause hazards such as short circuiting, fire, electric shock etc.
Read the instructions carefully and keep them. Make this product available to third parties only
together with its operating instructions.

Apart from opening the battery compartment lid, the the magnetic field tester's
casing must not be taken apart.
•
The device is not a toy. Keep it out of the reach of children and pets.
•
Do not leave packaging material lying around carelessly. These may become
dangerous playing material for children.
•
Protect the product from extreme temperatures, direct sunlight, strong jolts, high
humidity, moisture, flammable gases, vapours and solvents.
•
Do not place the product under any mechanical stress.
•
If it is no longer possible to operate the product safely, take it out of operation and
protect it from any accidental use. Safe operation can no longer be guaranteed if
the product:
-
is visibly damaged,
-
is no longer working properly,
-
has been stored for extended periods in poor ambient conditions or
-
has been subjected to any serious transport-related stresses.
•
Please handle the product carefully. Jolts, impacts or a fall even from a low height
can damage the product.
b)
(Rechargeable) batteries
•
Correct polarity must be observed while inserting the (rechargeable) batteries.
•
(Rechargeable) batteries should be removed from the device if it is not used
for a long period of time to avoid damage through leaking. Leaking or damaged
(rechargeable) batteries might cause acid burns when in contact with skin, therefore
use suitable protective gloves to handle corrupted (rechargeable) batteries.
•
(Rechargeable) batteries must be kept out of reach of children. Do not leave
(rechargeable) batteries lying around, as there is risk, that children or pets swallow
them.
•
All (rechargeable) batteries should be replaced at the same time. Mixing old and
new (rechargeable) batteries in the device can lead to (rechargeable) battery
leakage and device damage.
•
(Rechargeable) batteries must not be dismantled, short-circuited or thrown into fire.
Never recharge non-rechargeable batteries. There is a risk of explosion.
c)
Miscellaneous
•
Consult an expert when in doubt about operation, safety or connection of the

INSERTING/REPLAcING ThE BATTERIES
For the initial commissioning, and when the tester or the LED lamp do not work any longer, the
batteries must be replaced. 2 batteries are enclosed with the tester.
Proceed as follows, to insert or replace the batteries:
1.
Carefully press down the bar, between
the attachment clip (4) and the switch for
the LED lamp (5), and pull the battery
compartment (6) backwards from the tester.
2.
Insert two micro-batteries (AAA) into
the battery compartment. Pay attention
to the polarity indication in the battery
compartment. Use alkaline batteries, as
they guarantee a longer running time.
3.
Close the battery compartment again,
carefully.
START-UP AND OPERATION
Before each measurement, check the magnetic field tester is functioning by
using the enclosed test magnet.
a)
function test
Check the correct functioning of the magnetic field tester prior to each test. For this, a permanent
magnet is provided for testing.
1.
Slide the magnet (7) from the back of the device.
2.
Press the test key (3) and hold it during the test period.
3.
Move the magnet to the front of the test tip.
4.
The test gauge (2) will light up and an acoustic signal will sound when a magnetic field has
been detected. If this is not the case, check the batteries and, if necessary, replace them.
5.
When the test key is released, the tester is turned off. Attach the magnet to the tester
again.
b)
Test mode
1.
Press the test key (3) and hold it down during the test period.
2.
Place the test tip by the object that you wish to test.
3.
The test gauge (2) will light up and an acoustic signal will sound when a magnetic field
has been detected. If the display lightens up briefly, this might be caused by adjoining
components.
4.
When the test key is released, the tester is turned off.
c)
LED Torch
Press the switch (5). The LED lamp (6) on the back of the tester lights.
cLEANING
The tester is maintenance-free, apart from the need to replace the batteries and occasional
cleaning. Use a dry, clean, lint-free, antistatic cloth to clean the device. Do not use any abrasive
