Warranty Conditions Worldwide

Warranty conditions worldwide

The manufacturerRudolph Tietzsch GmbH & Co. KG grants a 3-year guarantee on the products advertised with guarantee promises (voltage testers, high-voltage testers, telescopic voltage testers, resistance and insulation testers). This warranty does not apply to accessories or included batteries. No other warranties such as suitability for specific applications are given. The manufacturer assumes no liability for incidental or consequential damage or loss, regardless of the cause.

The period for calculating the warranty period begins with the invoice date. The geographical scope of the manufacturer’s guarantee extends worldwide with the exception of the European Union (EU).

If material defects or manufacturing defects occur in the goods purchased by the buyer during this period, the manufacturer, as the guarantor, grants him one of the following services at his discretion within the scope of this guarantee:

  • – free repair of the goods or
  • – free exchange of the goods for an equivalent item


In the event of a warranty claim, please contact the guarantor

Rudolph Tietzsch GmbH & Co. KG
Willringhauser Str. 18

Warranty claims are excluded in the event of damage to the goods

  • – normal wear and tear (e.g. signs of wear on the lenses)
  • – improper or abusive handling (e.g. by overloading)
  • – non-compliance with any safety precautions or technical limits
  • – use of force (e.g. punches)
  • – do-it-yourself repair attempts
  • – environmental influences beyond the intended use (heat, humidity, etc.)


A prerequisite for claiming the guarantee is that the guarantor is able to check the guarantee case by sending in the goods. The goods must be sent in at the expense of the buyer.

It is important to ensure that damage to the goods during transport is avoided by using secure packaging. When applying for the guarantee, a copy of the invoice must be enclosed with the consignment so that the guarantor can check whether the guarantee period has been complied with. Without a copy of the invoice, the guarantor can refuse the guarantee service. Furthermore, the buyer must provide the name and address of the final seller if this data does not result from the copy of the invoice.

In the case of justified warranty claims, the warranty processing and return to the buyer are always free of charge. Warranty processing can be combined with other services offered by the seller (e.g. calibrations). In this case, the additional services are still subject to a charge.
