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 in-ground/2Pt), signal strength, and a timestamp. Though this
window lists all transmitters compatible with your receiver, only transmitter bands 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
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.

Note that the 15 m calibration button does not appear when the AGR screen appears immediately after
calibration.
