View Calibration
Use this feature to check the most recent calibrations for your transmitter(s). The data will
include the model of transmitter, type of calibration (1-point or 2-point), signal strength, and a
timestamp. Though this window lists all transmitters compatible with the Falcon F5 receiver,
only transmitters calibrated to your receiver will display data in the Signal and Timestamp
columns.
View Calibration Window
After calibrating a fluid pressure transmitter, turning the fluid
pressure feature on or off does not require a new calibration.
However, a separate calibration is required for each frequency
band if you want the option of switching between them mid-bore.

Above Ground Range (AGR)
After successfully completing a 1-point calibration, the receiver displays the Above Ground
Range screen, which is an active measurement between the transmitter and receiver. You
can also access this tool directly from the Main menu > Calibration > Above Ground Range
(AGR) . Use this screen along with a tape measure to verify calibration of the transmitter
at different depths/distances. With the transmitter level, the depth readings should be within
±5% of the measured distance.
AGR: It's Just What You Do Page 18
Performing an AGR test on both frequency bands at every jobsite is just good practice.

Note that because AGR intentionally does not consider pitch when
calculating range, it displays a symbol indicating "Warning, pitch is
unknown, assume zero". It also ignores any HAG setting.
