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 60 minutes. 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.
You must set the language used in the display when you switch the measuring tool on for the first time or after resetting it to factory settings. To select a language, press the multi-function button (12) up or down. Press the centre of the multi-function button (12) to confirm your selection. You can change the language via the main menu see Main Menu at any time.
To take a measurement, fold the protective cap (2) upwards. Make sure that the infrared sensor is not closed off or covered while working.
To switch on the measuring tool, press either the on/off button (11) or the centre of the multi-function button (12). After a brief start sequence, the set values for emissivity and reflected temperature are shown on the display for a few seconds. The laser is still switched off.
To switch off the measuring tool, press the on/off button (11) for longer than 1 s. The measuring tool saves all settings including the last measured values and then switches itself off. Close the protective cap (2) to transport the measuring tool safely.
In the main menu, you can choose whether and after how long the measuring tool automatically switches off if you do not press any buttons see Main Menu.
The measuring tool is equipped with a worklight (3). It is intended to illuminate the direct work area of the measuring tool and is not intended as a continuous worklight.
Press the button (15) to switch the worklight (3) on or off. When the worklight is switched on, the worklight symbol (a) will appear on the display.
The worklight is automatically switched off after 2 minutes to avoid affecting the measuring accuracy. You can change the automatic switch-off time in the main menu see Main Menu.
