* The measuring accuracy of the K-type temperature sensor has to be added
to the specified measuring accuracy.
Wire temperature sensor (type K): Measuring range: - 60 °C to 200 °C
Measurement accuracy: ± 2 °C
The measuring accuracy applies to stable ambient temperatures < ± 1 °C. After
a change of the ambient temperature of ± 2 °C, the measuring accuracy data
will apply after 1 hour.

8. Measuring with the BENNING MM 7-1
8.1 Preparation for measuring
Store and use the BENNING MM 7-1 only under the correct temperature condi-
tions stated. Always avoid longer exposure to sunlight.
- Check the rated voltage and rated current stated on the safety measuring
leads. The safety measuring leads supplied with the unit are suitable for the
