Starting operation
- Protect the measuring tool from moisture and direct sunlight.
- Do not expose the measuring tool to any extreme temperatures or variations in temperature. For example, do not leave it in a car for extended periods of time. In case of large variations in temperature, allow the measuring tool to adjust to the ambient temperature before putting it into operation. The precision of the measuring tool may be compromised if exposed to extreme temperatures or variations in temperature.
- Make sure that the measuring tool is correctly acclimatised. In case of large variations in temperature, acclimatisation can take up to 30 min, or up to 90 min in extreme situations. This may be the case, for example, if you store the measuring tool in a cool car and then perform a measurement in a warm building.
- Avoid hard knocks to the measuring tool or dropping it. After severe external influences and in the event of abnormalities in the functionality, you should have the measuring tool checked by an authorised Bosch after-sales service agent.
- Do not close or cover the humidity and temperature sensor (4), the reception lens (3) or the laser outlet aperture (2).
Switching on/off
You can switch on the measuring tool by pressing the ON/OFF button/mode button (12) or the measure button (1). After a brief start sequence, the measuring tool is ready to use – always in surface temperature mode and with the emissivity that was saved when the tool was last switched off. No measurement is initiated at this stage and the laser is still switched off. After pressing the measure button (1), the measuring tool begins measuring.
- Never leave the measuring tool unattended when switched on, and ensure the measuring tool is switched off after use. Others may be dazzled by the laser beam.
- Do not direct the laser beam at persons or animals and do not stare into the laser beam yourself (even from a distance).
To switch off the measuring tool, press the ON/OFF button/mode button (12) for approx. 2 s.
If no button on the measuring tool is pressed for approx. 5 min, the measuring tool will automatically switch itself off to preserve battery life.
