Do not subject the tool to extreme
temperatures or variations in temperature.
As an example, do not leave it in vehicles for
longer periods. In case of large variations in
temperature, allow the tool to adjust to the
ambient temperature before putting it into
operation. In case of extreme temperatures or
variations in temperature, the accuracy of the
tool can be impaired.
It is the user's responsibility to periodically
check the accuracy of the measuring tool
as work progresses. Always check the
accuracy of the measuring tool after it
has been dropped or subject to extreme
temperatures and temperature variations.
Avoid heavy impact or and prevent the
