2 Point Calibration (In Ground)
The 2PT CAL option allows you to calibrate the receiver to the transmitter when it is in the ground. This
procedure requires the use of a tape measure. Two-point calibration is rarely needed. If you must
calibrate with the transmitter in the ground, use this procedure with caution.
Position the receiver on the ground above an approximately level transmitter. (See the Locating section
for instructions on how to position the receiver directly over the transmitter.) Start the 2-point calibration
procedure by selecting 2PT CAL from the calibration menu. You will see the following screen.
First Point, 2PT CAL
The flashing trigger symbol at the top of the screen indicates that a trigger click is needed to obtain the
first point for the 2-point calibration. Click the trigger, and the display will count down from 5 to 0 while the
receiver records the first calibration point.
If the signal strength from the transmitter is within the tolerable range (300950 points), a checkmark will
display on the screen and you will hear the confirmation signal indicating that the first calibration point has
been successfully recorded. Then the second 2PT CAL screen appears.
