Recalibration
The measuring tasks performed with your instrument, and the
stressing it’s subjected to, influence aging of its components and
may result in deviation from the specified levels of accuracy.
In the case of strict measuring accuracy requirements, as well as
in the event of use at construction sites with frequent stress due
to transport and considerable temperature fluctuation, we recom-
mend a relatively short calibration interval of once per year. If your
instrument is used primarily in the laboratory and indoors without
considerable climatic or mechanical stressing, a calibration inter-
val of once every 2 to 3 years is sufficient as a rule.
During recalibration* at an accredited calibration laboratory
(DIN EN ISO/IEC 17025), deviations from traceable standards
demonstrated by your measuring instrument are documented.
Ascertained deviations are used to correct display values during
later use of the instrument.
We would be happy to perform DAkkS or factory calibration for
you at our calibration laboratory. Further information is available

Recalibration of your instrument at regular intervals is essential for
the fulfillment of requirements according to quality management
systems per DIN EN ISO 9001.
Note
Regular calibration of the test instrument should be per-
formed in a calibration laboratory which is accredited per
DIN EN ISO/IEC 17025.
* Examination of the specification, as well as adjustment, are not included
in calibration. However, in the case of our own products, any required
adjustment is performed and adherence to the specification is con-
firmed.

Attention!
!
Measurements per DIN EN 61010-031 may only be per-
formed in environments in accordance with measuring
category III with the safety cap attached to the test probe
at the end of the measurement cable.
In order to establish contact inside 4 mm jacks, the safety caps
have to be removed by prying open the snap fastener with a
pointed object (e.g. the other test probe).
