Starting Operation

• 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.

• 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.

• Avoid substantial knocks to the measuring tool and avoid dropping it. After strong external influences on the measuring tool, you should always carry out an accuracy check  see Accuracy Check before further work.
