4. Click the trigger to initiate calibration. The screen will show that the receiver is calibrating. Do not
move the receiver.

5. When calibration is complete, the confirmation signal will sound and a checkmark will display on
the screen, indicating a successful calibration. The screen will then return to the locate mode
display. If calibration fails, two long beeps will sound and the calibration failure screen will display.
Verify the setup and try again or call DCI Customer Service.
After successfully completing the 1-point calibration procedure, take a depth measurement with the
transmitter and receiver in the same orientation as during calibration. The depth should be 10 ft ± 5 in. (or
3 m ± 15 cm). Take another depth reading at some other measured distance and verify that the depth
reading on the display remains accurate.
NOTE: If depth data does not display, you will need to obtain a reference lock (“R”). See discussion
under “Finding the Front Locate Point (FLP)” in the Locating section for information on obtaining
a reference lock.
2-Point Calibration (In Ground)
The 2-point calibration procedure is rarely needed. It requires you to obtain two calibration points, one
with the receiver placed on the ground and one with the receiver raised 3 ft (or 1 m) above the ground. If
you must calibrate with the transmitter in the ground, use this procedure with caution.
1. With the receiver in locate mode, position the receiver directly above an approximately level
transmitter (see the Locating section for instructions on aligning the receiver directly above the
transmitter and ensuring that the transmitter is level).
2. Verify that the signal strength readings with the receiver on the ground and with it raised 3 ft (or
1 m) above the ground are between 300 and 950 points. If the signal strength is too high with the
receiver on the ground, then lift the receiver until the signal is within an acceptable range. The
second point should then be measured 3 ft (or 1 m) above that point. If the signal is too low, you
will have to pull back to calibrate.
3. Verify that roll and pitch values are being displayed on the receiver and that a steady signal is
being received from the transmitter.
