5. Calibrate Both Bands
Calibration in an interference-free environment
is required after any optimization.
a.
Place the Tx in a housing on level ground
10 feet from locator as shown.
b.
From the Main menu, select
Calibration
>
1 PT CAL
and calibrate each new band.
After the calibration, the Above Ground Range
(AGR) screen opens automatically.
6. Check Above Ground Range (AGR)
Always check AGR with a tape measure to
verify depth readings on each band at various
distances up to the maximum expected bore
depth. Distance readings should be within ±5%.
Access AGR
directly on the
Calibration
menu. Calibrate and check AGR for both new
bands.
If you selected two bands, repeat steps 5-6 (Calibration and AGR) for the
second band. An error symbol will display in the roll indicator on the Locate
screen until a 1 point calibration is completed for the current band.
Settings Menu
Use the Settings menu
to set the depth units, pitch units, telemetry
channel, contrast, LOC security options, level check, and roll offset.
Height-Above-Ground (HAG) Menu
Height-Above-Ground (HAG) is the distance from the ground to the
bottom of the locator while it is held. Setting HAG
on the Main menu
lets you take accurate below-ground depth measurements without having
to place the locator on the ground.
