TX Calibration
The transmitter calibration (adjustment) function fixes errors in
incline in the self-leveling mechanism of the transmitter, applying an
offset to the transmitter. The transmitter must be in calibration mode
for this function and the Rover setup approximately 30 meters (100
feet) away. The height of the sensor must be at an angle less than 1° in
relation to the transmitter.
To begin a resection, tap
TX Calibration
on the
Transmitters
tab of
the
transmitter setup
dialog box. If needed, check the setup listed

on-screen (Figure 2-30 on page 2-22) and tap
OK
.
NOTICE
If the sensor experiences excessive movement
during any stage of the adjustment, an error
message will display. Press Cancel and stabilize the
Rover pole. Then press TX calibration again.
