Switching On and Off

To take a measurement, fold the protective cap (1) upwards. Make sure that the infrared sensor is not closed off or covered while working.

To switch on the measuring tool, press the on/off button (9). A start sequence will appear on the display (14). The measuring tool begins to take measurements as soon as the start sequence has finished and does so continuously until it is switched off.

Note: In the first few minutes, the measuring tool may self-calibrate several times, as the sensor temperature and ambient temperature have not yet been brought into line. Performing sensor calibration again enables precise measurement.
During this time, the temperature indicator may show ~. The thermal image will freeze briefly during sensor calibration. If the ambient temperature fluctuates significantly, this effect is increased. If possible, you should therefore turn on the measuring tool a few minutes before starting to measure, so that the tool can stabilise thermally.

To switch off the measuring tool, press the on/off button (9) again. The measuring tool saves all settings and then switches itself off. Close the protective cap (1) to transport the measuring tool safely.

In the main menu, you can choose whether and after how long the measuring tool automatically switches off see Main Menu.

If the battery pack or the measuring tool is not within the operating temperature range specified in the technical data, the measuring tool will switch off automatically after a brief warning see Errors – Causes and Corrective Measures. Allow the measuring tool to reach the correct temperature and then switch it back on.
