Do not calibrate if:
l
You are within 10 ft. of metal structures, such as steel pipe, chain-link fence,
metal siding, construction equipment, automobiles, etc.
l
The receiver is over rebar or underground utilities.
l
An
A
is displayed at the bottom left of the roll indicator on the locating screen,
as this indicates signal Attenuation is in effect, likely due to excessive
interference. If possible, relocate to a quieter location before calibrating.

l
The receiver is in the vicinity of extreme interference, as shown by high
background noise readings on the frequency optimizer graph or a flashing
signal strength value on the locate screen along with the
A
icon (calibration is
prohibited when the signal strength is flashing).

l
The receiver is not displaying transmitter data.
l
The signal strength from the transmitter is less than 300 points (too low) or
greater than 950 points (too high). Outside this range, a calibration failure
screen will indicate low or high signal strength.
The transmitter must be installed in a drill head during calibration.
During calibration, Height-Above-Ground (HAG) is automatically turned
off. After calibration, HAG must be turned back on manually.

1-Point Calibration
Calibrating depth readings is accomplished above ground, prior to drilling.
1. Place the receiver and the transmitter (in a drill head) parallel to each other on level ground, with
both devices powered on.
2. With the receiver at the Locate screen, verify that roll and pitch values are being displayed and that
a steady signal is being received from the transmitter. The transmitter’s signal strength at
calibration is available on the second page of the Settings menu. A change in signal strength at 10
ft. later can indicate you are currently in an interference environment or there is a problem with your
equipment.
3. Move the locator within 2 ft. of the transmitter to enable signal
, indicated by an
A
at the
bottom left of the roll indicator. Move the locator back to 10 ft. away and verify attenuation turns off.
If it does not, excessive noise may be present.
