Calibrating the Receiver

There are two different calibration methods: 1-point and 2-point. The 1-point calibration is performed with the transmitter in the housing parallel to and 10 ft 5 in. (3.18 m) from the receiver, as described below. A 2-point calibration is generally performed when the transmitter is below ground and it is not possible to perform a 1-point calibration.

Calibration is necessary prior to first time use and when any of the following occur:

¾The transmitter is changed.

¾The receiver is changed.

¾The housing/drill tool is changed.

Do not calibrate if:

¾You are within 10 ft (3 m) of metal structures, such as steel pipe, chain link fence, metal siding, con- struction equipment, or automobiles.

¾The receiver is over rebar or underground utilities.

¾The receiver is in the vicinity of excessive electrical interference (see “Electrical Interference/ Background Noise Check” in the Signal Interference Section).

¾The transmitter is not installed into the housing.

¾The transmitter is not turned on.

NOTE: Calibration should be checked at 10 ft 5 in. (3.18 m) daily and before every use. Calibra- tion only affects the depth/distance reading, not pitch or roll.

1-Point Calibration Procedure

1.Confirm the lack of interference (see Electrical Interference/Background Noise” Check in the Signal Interference Section). Make sure there are no other active transmitters within range of the receiver.

2.Place an operating transmitter inside the housing on level ground.

3.After the receiver has completed the start-up sequence, place it exactly 10 ft 5 in. (3.18 m) from the housing as shown in the sketch (a tape measure must be used for accuracy; measure from centerline

of transmitter to inside edge of re-
