Starting Operation

Switching on/off

Before switching on the measuring tool, ensure that the sensor area (8) is dry. If necessary, use a cloth to dry the measuring tool.

If the measuring tool has been exposed to a significant change in temperature, leave it to adjust to the ambient temperature before switching it on.

To switch on the measuring tool, push the on/off switch (2) down.

The measuring tool carries out a short self-check and calibrates itself automatically. Once the light-up ring (5) turns green, the measuring tool is ready to use.

To switch off the measuring tool, push the on/off switch (2) up.

If no measurement takes place for approx. 10 minutes, the measuring tool automatically switches off to save the batteries.

Note: When the measuring tool has switched off automatically, the on/off switch (2) will still be in the "on" position. To switch the measuring tool on again, first switch it off and then switch it on again.
