Voltcraft MS-430 Multi-Tester MS-430 Ficha De Dados

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 

names and product names are trademarks of their respective owners. All rights reserved.
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.

•  Voltage detector
•  2 x AAA battery
•  Operating instructions

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.

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. 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.

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.
