# Operation

- Check the levelling and display accuracy of the measuring tool each time before beginning work and after longer transport of the measuring tool.

- 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 any impact to or dropping of the measuring tool. Always carry out an accuracy check before continuing work if the measuring tool has been subjected to severe external influences see Accuracy Check of the Measuring Tool.

- Place the measuring tool in the provided case when transporting it over longer distances (e.g. in the car). Ensure that the measuring tool is correctly placed in the case. When placing in the case, the compensator is locked, as the measuring tool may otherwise be damaged by strong movements.
