1-Point Calibration
The 1-point calibration procedure is performed with the transmitter in the housing parallel to and 10 ft
(3 m) from the receiver, as described below. DCI does not recommend calibrating every day, but you
should verify the receiver’s depth readings at several locations using a tape measure.
Calibration is necessary prior to first-time use and when any of the following occur:
¾ The transmitter is changed.
¾ The receiver is changed.
¾ The housing/drill tool is changed.
Do not calibrate if:
¾ You are within 10 ft (3 m) of metal structures, such as steel pipe, chain link fence, metal siding,
construction equipment, or automobiles.
¾ The receiver is over rebar or underground utilities.
¾ The receiver is in the vicinity of excessive electrical interference.
¾ The transmitter is not installed into the housing.
¾ The transmitter is not turned on.
1-Point Calibration for Standard, Mini, and Long-Range Transmitters
1. Power up the Eclipse receiver.
2. Toggle right past the Configure menu to verify that you see Low Fre on the main menu screen. If
you see High Fre, then select it, and click the trigger so that the menu option will change to Low Fre.
3. Select Locate, and click the trigger.
4. Power up the standard, mini, or long-range transmitter, and place it into the housing. Verify that the
transmitter is sending proper pitch, roll, battery, and temperature status information.
5. With the transmitter in the housing, measure 10 ft (3 m) from the centerline of the transmitter to the
bottom inside edge of the receiver below the display window (see figure)—this should be measured to
the bottom inside edge of the receiver where it meets the ground, not the upper edge at the display,
which is wider.

6. Verify that the signal strength at 10 ft (3 m) is approximately 528 for the standard transmitter, 360 to
370 for the mini transmitter, or 620 for the long-range transmitter, and record the value.
7. Select Configure on the main menu display, and click the trigger.
