Magnetic Field Tester MS-410
Item-No. 12 30 04
Intended Use
The magnetic field tester is intended for detecting constant and alternating magnetic fields. The Tester is ide-
al 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. When a magnetic
field is detected, the test tip starts to flash. 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.
Please, also take note any additional safety information in these instructions.
Safety Instructions and Hazard Warnings
An exclamation mark in a triangle indicates important instructions in the operating
instructions. Please read all the instructions before using this device, they include
important information on its correct operation.
- The warranty will be void in the event of damage caused by failure to observe these safety instructions! We
do not assume any liability for any consequential damage!
- Nor do we assume any liability for material and personal damage caused by improper use or non-compli-
ance with the safety instructions! The warranty will be void in such cases.
- The unauthorised conversion and/or modification of the unit is not permitted because of safety and
approval reasons (CE).
- Extra care should be taken when using the device for the first time. Therefore, please follow the operating
instructions carefully.
- The device must not be exposed to extreme temperatures, strong vibrations or high levels of humidity.
- Only hold the magnetic field tester by its handles. Never take hold of the device beyond the raised mark-
ings on the handles.
- The device contains magnetic components. Keep these parts away from people with sensitive implants (e.
g. cardiac pacemakers, etc.).
- Apart from opening the battery compartment lid, the the magnetic field tester's casing must not be taken
apart.
- Keep the magnetic field tester clean and store it in suitable place.

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:
- Carefully press down the bar, between the attach-
ment clip (4) and the switch for the LED lamp (5),
and pull the battery compartment (6) backwards
from the tester.
- 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.
- Close the battery compartment again, carefully.
Do not leave flat batteries in the device. Even batteries that are leak-proof can corrode
and thus release chemicals that could be detrimental to your health or damage the
device.
Batteries, including rechargeable batteries, must not be short-circuited or thrown into a
fire. Batteries (non-rechargeable) must not be recharged. There is a risk of explosion.

Leaking or damaged batteries/rechargeable batteries can cause chemical burns if they
come into contact with the skin.. Therefore, use suitable protective gloves.
Always change all of the batteries at the same time. Do not mix new batteries with used
ones, since these may start to leak.
®
Suitable batteries can be ordered using the order no. 65 23 03. Please order 2 batteries.
Start-up and Operation
Before each measurement, check the magnetic field tester is functioning by using the
enclosed test magnet.
Function test
Check the correct functioning of the magnetic field tester prior to each test. For this, a permanent magnet is
provided for testing.
- Slide the magnet (7) from the back of the device.
- Press the test key (3) and hold it during the test period.
- Move the magnet to the front of the test tip.
- The check indicator (2) must flash. If this is not the case, check the batteries and, if necessary, replace
them.
- When the test key is released, the tester is turned off. Attach the magnet to the tester again.
Test mode
- Press the test key (3) and hold it down during the test period.
- Place the test tip by the object that you wish to test.
- The test tip (2) flashes when a magnetic field has been detected. If the display lightens up briefly, this might
be caused by adjoining components.
- When the test key is released, the tester is turned off.
LED Torch
- Press the switch (5) until it clicks into place. The LED lamp (6) on the back of the tester lights.
- To turn off, press the switch again. The lamp is turned off.
- Always switch off the LED lamp after use, otherwise the batteries are discharged too soon.
Maintenance and 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 or chemical agents or deter-
gents containing solvents.
Periodically, check the technical safety of the tester.
It can be assumed that correct operation is no longer possible if:
- the device is visibly damaged,
- if the device was stored under unfavourable conditions for a long period of time
- if it was exposed to extraordinary stress caused by transport
- the test function, described above, does not work as it should.
Do not try to open the casing, apart from the battery compartment.
Disposal of used batteries/rechargeable batteries!
As a consumer you are required (Battery Ordinance)to responsibly dispose of all used batteries and
rechargeable batteries;it is forbidden to throw them away with the normal household waste!
Contaminated batteries/rechargeable batteries are labelled with these symbols to indicate that
disposal in domestic waste is forbidden. The symbols for dangerous heavy metal constituents
are: Cd = Cadmium, Hg = Mercury, Pb = Lead. You can return used (rechargeable) batteries
free of charge at the official collection points in your municipality, our stores, or where ever
(rechargeable) batteries are sold!
You thus fulfil the legal requirements and make your contribution to protecting the environment!
Disposal
Electronic products are raw material and do not belong in the household waste. When the
device has reached the end of its service life, please dispose of it, according to the current
statutory requirements, at your local collecting site. Disposal in the domestic waste is not per-
mitted!
