These results may also indicate that the operator should reposition the transmit-

2. Type and conductivity of soil.
3. Receiver not centered on target.
4. Depth of burial versus size of target.

depth readings.
6. Changing conductor depth or a tilted conductor at the reading location.

**NOTE**
THIS CONDITION MAY BE EVALUATED USING TWO METHODS. ONE
METHOD IS BY PIVOTING THE RECEIVER 180 DEGREES WHICH MAY
-
RESULT OF A TILTED CONDUCTOR WHICH OCCURS NATURALLY
WHERE A FORWARD OR RE- VERSE GRADE EXISTS. DIFFERENCES
SECOND METHOD IS SOMETIMES CALLED THE “LIFT TEST” AND IN-
VOLVES TAKING A STANDARD CALCULATED DEPTH READ- ING AND
THEN LIFTING THE RECEIVER UP A KNOWN DIS- TANCE AND OB-
SERVING THE NEW CALCULATED DEPTH READING ON THE DISPLAY.
THE UPDATED CALCULATED DEPTH READING SHOULD INCREASE
BY THE DISTANCE THAT THE RECEIVER WAS RAISED. PIVOTING
THE RECEIVER MAY ALSO BE USED WITH THE LIFT TEST.
