The indicator on the display is continually updated. As soon as you let go of the measur-
ing button (3), the measurement is stopped, the indicator SCAN disappears and the
laser is switched off.
The most recent measurement reading and the reading before it are shown on the dis-
play.
Errors – causes and corrective measures
Measuring tool not acclimatised
The measuring tool has been subjected to extreme fluctuations in temperature and did
not have sufficient time to adjust.
Ambient temperature outside the operating temperature range
The ambient temperature is too high or too low for the measuring tool to operate.
Surface temperature outside the measuring range
The indicator flashes if the surface temperature of the object being measured in the
measuring area is too high (above 500 °C, see indicator (g)) or too low (below −30 °C,
see indicator (f)). The temperature of this object cannot be measured. Aim the laser at
another object and start a new measurement.
Internal error
If the measuring tool has an internal fault, Err is shown on the display and the (i) sym-
bol flashes. To reset the software, remove the batteries, wait a few seconds and then re-
insert the batteries.
If the error persists, have the measuring tool checked by a Bosch customer service
agent. Do not open the measuring tool yourself.
Glossary of terms
Emissivity
The emissivity of an object depends on the material and the structure of its surface. It in-
dicates whether a particular object emits a high or low level of infrared thermal radiation
(in comparison to other objects of the same temperature).
