Range Errors

A listing of Range Error messages is given in Table 2-3.

Table 2-3.Range Error Messages (1 of 2)

Error Message	Description
RANGE	The start (F1) frequency is greater than the stop (F2) frequency.
ERROR:F1 > F2
RANGE	The start (D1) distance is greater than the stop (D2) distance.
ERROR:D1 > D2
RANGE	The stop distance (D2) exceeds the maximum unaliased range. This
ERROR:D2 >	range is determined by the frequency span, number of points,
DMax=xx.x ft (m)	and relative propagation velocity:
	MaximumUnaliased Range ￿	(1.5 ￿ 108) (dp ￿ 1) (V f )
		F2 ￿ F1
	Where: dp is the number of data points (130, 259, or 517)
	Vf is the relative propagation velocity
	F2 is the stop frequency in Hz
	F1 is the start frequency in Hz
	Maximum Unaliased Range is in meters
	Refer to Figure -, page , for a plot of maximum range versus fre-
	quency span.
RANGE ERROR:	The SWR scale parameter top value is less than or equal to its bottom
TOP<=BOTTOM	value.
RANGE ERROR:	The RL scale parameter top value is greater than or equal to its bottom
TOP>=BOTTOM	value.
CAL	A complete open, short, and load calibration must be performed bef-
INCOMPLETE	ore calibration can be turned on.
DIST REQUIRES	Valid distance to fault plots require a non-zero frequency span.
F1 < F2
DIST REQUIRES	Distance-to-fault measurements cannot be performed with CAL OFF.
