MS-430 CONTACT-FREE VOLTAGE DETECTOR
ITEM NO.: 12 34 41
INTENDED USE
This product is designed for contact-free detection of alternating current (AC) voltages. It
measures stationary electrostatic fields that are generated by AC voltage via the insulation.
If AC voltage is present, this is displayed visually by a red LED and acoustically by an audio
signal. Additionally, the product has an integrated LED torch for illuminating dark corners. The
product is operated with two AAA batteries. Do not use any other power sources. Protect the
product from high levels of dampness and moisture.
This product complies with the statutory national and European requirements. All company

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.

SYMBOLS EXPLANATION
CAT III
CAT IV
An exclamation mark within an equilateral triangle indicates important information
in the operating instructions. Carefully read the whole operating instructions before
operating the device, otherwise there is risk of danger.
The lightning symbol with arrowhead within an equilateral triangle is intended to alert
the user to the presence of uninsulated voltage within the device’s enclosure that
may be of sufficient magnitude to constitute a risk of electrical shock to persons.
This device provides basic insulation with supplementary insulation.
The device is designed to protect against transients voltage from fixed installations
and building wiring. Examples include building wiring, industrial equipment with
permanent connection to fixed installation.
The device is designed to protect against transients voltage at or near the feed into
the electrical installation of buildings and that from the main distribution into the
direction of the system. Examples include electricity meters and overcurrent circuit
breakers.
SAFETY INSTRUCTIONS
Read the operating instructions carefully and especially observe the safety
information. If you do not follow the safety instructions and information
on proper handling in this manual, we assume no liability for any resulting
personal injury or damage to property. Such cases will invalidate the warranty/
guarantee.
a) Persons / Product
• The voltage between the measuring device and earth must not exceed 1000 V in
overvoltage category III and 600 V in overvoltage category IV.
• Apart from opening the lid of the battery compartment, the housing of the product
must not be taken apart.
• This device can be used in environment where only non-conductive pollution
occurred or temporary conductivity caused by condensation occurred occasionally.
• When operating the device, please equip proper protective equipment as required
by local or national authorises.
• 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
device.
• Maintenance, modifications and repairs are to be performed exclusively by an
expert or at a qualified shop.
If you are not sure about the correct connection or use, or if questions arise which are not
covered by these operating instructions, please do not hesitate to contact our technical support
or another qualified specialist.

1. Testing tip
2. Testing indicator (green / red)
3. On/Off button
4. Attachment clip
5. Battery compartment cover
6. LED light button
7. LED torch
INSERTING/REPLACING THE BATTERIES
1. Carefully press the bar between the attachment clip (4) and LED light button (6)
downwards and pull the battery compartment cover (5) backwards, away from the voltage
detector.
2. Insert two batteries (AAA) into the battery compartment. Observe the polarity markings in
the battery compartment.
3. Slide the battery compartment cover (5) back on until it audibly clicks into place.
When the batteries are discharged, the red testing indicator (2) will start blinking
and a series of audio signals will sound after turning the product on. The product will
subsequently turn itself off. Replace the two AAA batteries with new batteries of the same
type.
Replace the batteries when the testing indicator (2) appears weakened or the acoustic
signal becomes markedly lower in volume during operation.
OPERATION
a) Switching the product on/off
1. When switching the product on, you have the option to either activate or mute the audio
signal function for test operation. To do this, proceed as follows.
