Autolock technology

The instrument is equipped with Tracker technology.

Tracker technology controls the instrument servos and aims the instrument correctly towards the target.

TIP – To assure maximum performance from the Tracker technology keep the lens clean and dry.

When Target ID is added to the 360 degree prism, Trimble Field Software allows the Target ID to be used in one of three ways:

  1. Searching – The instrument only uses and checks the Target ID when looking for the prism, after which it returns to passive mode of operation, tracking the prism only.

  2. Searching and measuring – The instrument checks the Target ID when searching for the prism, and during measurement. If the appropriate Target ID is not seen, the field software will warn the user Target Not Found during measurement and on trying to record data.

  3. Only tracking horizontal – In this mode the instrument will use the Target ID as an Active target for tracking in the horizontal only, the vertical tracking is still carried out passively to the prism itself. For full active tracking use the MT900 target on machines and vehicle mounted operations or the MT1000 MultiTrack target on a pole.
