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 Focus 6 5" 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 a prism target is aimed in N-prism mode, the warning message
Signal
High! → Try Prism Mode
is displayed because of the excessive light reflection.
A measurement made immediately after changing the target setting may take longer
than usual.
Rec mode field
The Rec mode setting controls how the
[MSR1]
and
[MSR2]
keys operate in the BMS.
The MSR only setting is the default measurement mode. After a measurement, the
instrument stops in the BMS and waits for you to press
[ENT]
before recording the
point.
The Confirm setting displays the Record PT screen before data is recorded.
