Calibration and adjustment service
The certificates are categorised as ISO calibration certificates and DAkkS calibration
certificates. The purpose of the calibration is to verify the precision of the measuring
device by comparing it with a traceable reference.
The ISO standard 9001 is applied for the calibration certificates. These
certificates area affordable alternative to the DAkkS calibration
certificates and provide information of the traceable reference, a list of
individual values and documentation.
The DAkkS calibration is based on DIN EN ISO/17025, the
accreditation basis recognised worldwide. These certificates offer high-
quality calibration and consistently high quality. DAkkS calibration
certificates can only be issued by accredited calibration laboratories
which have demonstrated their expertise in accordance with DIN EN
ISO/IEC 17025. The ISO calibration includes any necessary
adjustment with the purpose of minimising a deviation of the measuring
device.
DAkkS calibration certificates are accompanied with a list of individual
measurements before and after the adjustment, documentation and, if
applicable, graphic representation, calculation of the expanded
measuring uncertainty and traceability to the national standard.
The product is delivered with a test report. This confirms that the
measuring device has been adjusted and tested.
Only the manufacturer can check the basic settings and make
corrections if necessary.

Replacing rechargeable batteries
Using damaged or unsuitable batteries can generate heat, which can
cause the batteries to crack and possibly explode!
If the batteries have different charge levels, leaks and thus damage to
the product can occur.
- Use new, high-quality batteries!
- Do not use different types of batteries!
- Remove depleted batteries and dispose of them at a suitable
collection point!
Unnecessary screwing places the water-tightness of the product,
among other things, at risk and should be avoided.
