Collect Screens
TRIUMPH-LS is mounted on a pole and plumb. This feature
will correct for any internal misalignment of the level
sensor and also correct for any misalignment between the
TRIUMPH-LS and the rover pole. It is also used to correct
the fluctuations in the level readings that occur due to
temperature changes. The Calibrate Level procedure should
be done prior to calibrating the Level Offsets if the level
readings are greater than 1.5° when the TRIUMPH-LS is
level.
To calibrate the Level Offsets press the Level Offset button
and the Calibrating Level Offset screen will open:
The black Roll and Pitch numbers indicate the current offset
that is being applied to the internal level readings. These
numbers are the calculated Level Offsets from the previous
calibration. The red Roll and Pitch numbers indicate the
readings of the levels after the Level Offsets are applied. The
red numbers are the same values that are displayed on the
Collect and Stake screens in the Heading and Tilt box.
With the TRIUMPH-LS mounted on the rover pole you
are using to survey, plumb the pole using the pole’s level
bubble. Once plumb, press the Calibrate button. A 3 second
delay before the calibration begins will occur to you allow
you level and steady the rover pole and TRIUMPH-LS. The
calibration takes about 1 second after it begins. The results
will be presented and you are given the option to reject or
accept the calibration:
After pressing Accept, the calibration is stored and the
current level readings should be very close to zero when the
unit and pole are plumb:
