Errors – causes and corrective measures

Measured values outside the measuring range

If the measured values for the object being measured in the laser circle are outside the measuring range, the following indicators are shown on the display:

> 500 °C – the surface temperature is too high.

< –30 °C – the surface temperature is too low.

For an ambient temperature: > 50 °C (too high) or < –5 °C (too low)

The values of this object cannot be measured. Aim the laser circle at another object and start a new measurement.

Internal error

The measuring tool has experienced an internal error and switches off after five seconds. To reset the software, remove 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.
