The
symbol indicates low signal strength, and
indicates high (excessive) signal strength.
Calibration will fail when the signal from the transmitter is below 300 or above 950 points. Calibration
will also fail if extreme signal
(
A
) is in effect.
Continue with AGR in the next section to verify above-ground distances for this calibration.
If you just completed AGR after calibration, don't forget to turn
Height-Above-Ground (HAG) back on, if necessary.

Why do I keep getting calibration errors?
Carefully review the items under
at the beginning of this section. Try
calibrating in a different location. Make sure the transmitter is on and paired (data showing on
the Locate screen). If you're still having trouble, give us a call, we'll get you going.
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. 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 at every jobsite is just good practice.
To perform an AGR check without re-calibrating the transmitter, follow the
instructions in the previous section but do not click the trigger to perform
the calibration . The procedure will default to the AGR screen after several seconds.
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.
