#### Leica Options tab

Machine Options dialog box - Options tab

The Options tab provides the means to execute various TCU (Tracker Control Unit) Options and configure communication and other parameters. TCU options are also available as menu items.

TCU Options - This area allows you to execute the following options:

- Go Birdbath - Resets the Leica Tracker position by pointing to the Birdbath position. This provides a known and convenient location at which you can recapture the beam. This may be necessary if the beam to the T-Probe or Reflector has been broken.

- Initialize - PC-DMIS will send information to the Leica Tracker that will cause it to go through a process that is similar to a warm boot of a computer. The tracker goes through a series of movements to verify functionality.

- Level to Gravity - Start the process to determine true gravity using the Nivel 20/230 device. PC-DMIS will create an alignment which is leveled to gravity upon successful execution of this command.

- Motors Off - This will release the tracker motors so you can manually move the tracker head to the desired position.

- Reset Nivel - Makes a new reference measurement.

- Zero Pos (6DoF) - Moves to a zero position for the T-Probe. This provides a known and convenient location at which you can recapture the beam with the T-Probe.

IP Address - Specify the IP address of your Laser Tracker controller (default 192.168.0.1).

Update Interval - This interval is provided by emScon rather than being defined here.

Vector Interval - Not currently used

Vector Distance - This defines the distance that you need to move the T-Probe from normal hit location while holding the button to register a "Pulled Hit".

Vector Option - Choose one of these vector options:

- Use Vector Distance - Allows you to establish the vector using a "Pulled Hit".

- Use Last IJK - Uses the same IJK vector values of the last measured point.

- No vector - When this option is selected, you are able to produce scan data when you press and hold a button on the T-Probe.

"Pulled Hit" - Changes the vector to that of the line between the location where you first depress the hit button (at the normal hit location) to the location where you release the hit button. This line must be longer than the Use Vector Distance to successfully register a "Pulled Hit".

"Normal Hit" - A "Normal Hit" is taken when press and release the hit button in the same location.

Measurement Time - This determines the time interval in milliseconds. The data stream of measurements of the IFM is averaged, in this time interval, to a single measurement value. 500ms = 500 measurements in 500ms. This results in an XYZ coordinate with an RMS quality indication which is available on the DRO.

Note: Measurement Time supports a value between 500ms and 100000ms (.5 - 100 seconds)
