Trimble Slant HR -> HR
(From any HR field), Trimble Slant HR -> HR
This option only applies when using a Trimble Traverse Kit that
allows the measurement of a Slant HR instead of the usual HR.
When this option is selected, it will convert a Slant HR entered in an
HR field to a standard HR. This must be performed each time a new
Slant HR is entered in the HR field.
Consult the documentation that came with the Trimble Traverse Kit
for more information on correctly measuring a Slant HR.
Convert Slant HI to HI
(From any HI field), Convert Slant HI to HI
This option is only available when using a Trimble total station that
supports a Slant HI instead of the usual HI, such as a Trimble S6.
When this option is selected, it will convert a Slant HI entered in an
HI field to a standard HI. This must be performed each time a new
Slant HI is entered in an HI field.
Consult the documentation that came with the Trimble Total Station
from more information on correctly measuring a Slant HI.
