Settings that relate to corrections (T-P corr, Sea Level,
C&R corr., and Map projection) are included in the job
settings and are job-specific. To change any of these
settings, you must create a new job. See also Job,
page 86, and Settings (basic job settings), page 90.
Viewing and changing the measurement settings
1. Hold down [MSR1] or [MSR2] for one second.
2. To move the cursor between the fields, press
[^] or
[v].
3. To change the value in the selected field, press
[<]
or
[>].
Target field
• If the measurement is started with the Target
field set to Prism, there is a dash “–” in front of
the prism constant.
• If the measurement is started with the Target
field set to N-Prism, there is a right square
bracket “]” in front of the prism constant.
The symbol then continuously moves from left to right over the prism constant
in the display.
The Target setting is used by the TS635 Construction Total Station to apply better
cyclic-error adjustment in distance measurement. The target setting efficiently
eliminates multipath reflection.
An incorrect Target setting may result in measurements outside the precision and
intervals specified for the instrument.
If you aim a prism target in the N-prism mode, the warning message
Signal
High!→Try Prism Mode
appears because of the excessive light reflection.
A measurement made immediately after changing the target setting may take a longer
time than usual.
