precise specifications before leaving the factory. It is recommended to
perform accuracy test before the first-time use and perform test regularly,
especially during high precision requirements.
Turn the meter off and make sure the pendulum is locked when it is not in use.
In the manual mode, the self-leveling mode is off, which means the laser
beam cannot be horizontal/vertical reference.
