that is introduced when taking a shot to the prism at an
extreme vertical angle. The icon is displayed to help the
user identify that the correct prism is selected and the Prism
Constant is automatically set to 2 millimeters.
• Trimble MultiTrack (10mm): Select this option when using a
Trimble MultiTrack prism. The icon is displayed to help
the user identify that the correct prism is selected and the
Prism Constant is automatically set to 10 millimeters. (See
note below.)
Note: When using a Trimble MultiTrack prism in passive mode
(active tracking turned off), it is important to leave the Use Target ID
box unchecked and if the active tracking is enabled, to leave Use
Target ID box checked since a different vertical correction is applied
for each case.
Use Target ID: When checked, the Target ID can be selected for the
Smart Target. (This option is only available when using a total
station and prism that supports target IDs.)
• Use For Searching: When selected, the total station will
check the Target ID only when searching for the prism and
then track the prism. (Once the prism is being tracked, the
total station can potentially start tracking a different reflector
that comes into view.)
• Use Always: When selected, this forces the total station to
continuously check the Target ID; even while tracking the
prism eliminating the possibility of the total station tracking
a different reflector that comes into view.
Using Active Prism: Check this option when using an active prism.
(This option is only available when using a total station that supports
active prisms.)
Note: In order to perform automatic repetitions when using active
prisms, active prisms must be set up over both the backsight and
foresight.
