Internal error
Glossary of terms
Emissivity
The emissivity of an object depends on the material and the structure of its surface. This
specifies how much infrared thermal radiation the object emits compared with an ideal
radiant warmer (black body, emissivity ε = 1) and accordingly has a value between 0 and
1.
Thermal bridge
A thermal bridge is defined as a position on the external wall of a building, where there is
a localised increase in heat loss due to a structural defect.
Thermal bridges can lead to an increased risk of mould.
Relative humidity
The relative humidity indicates the degree to which the air is saturated with water va-
pour. The value is indicated as a percentage of the maximum amount of water vapour the
air can absorb. The maximum amount of water vapour depends on the temperature: The
higher the temperature is, the more water vapour the air can absorb.
If the relative humidity is too high, there is an increased risk of mould. If the relative hu-
midity is too low, it may have a negative impact on your health.
Dew point temperature
The dew point temperature indicates the point at which the water vapour in the air starts
to condense. The dew point temperature depends on the relative humidity and the air
temperature.
Bosch Power Tools
The measuring tool has experienced an internal error and
switches off after five seconds. To reset the software, re-
move the batteries, wait a few seconds and then reinsert the
batteries.
If the error persists, have the measuring tool checked by a
Bosch customer service agent.
