Distortion
Electromagnetic receivers like the SR‑24 require a sig‑
nal directly from the target utility without modification
by environmental factors to obtain optimal accuracy�
Environmental factors can include the presence of near‑
by metallic conductors or the addition of electromagnetic
fields from other sources like fields radiating from adja‑
cent utilities� These factors may distort the shape of the
field received by the SR‑24 and are experienced by the
SR‑24 as distortion� The SR‑24 uses its Omnidirectional
antennas and gradient antennas to measure distortion
and provide audio and on‑screen indicators�
Nearby metallic conductors can distort the shape of the
target line's electromagnetic field� The SR‑24 gives three
different indicators to alert you that distortion is present�
Take extra precautions when distortion is present to
confirm the accuracy of the locate.
Note: Refer to the Improving and Confirming Accuracy
section for information on improving the locate.
The Tracing Line Distortion Response activates when dis‑
tortion is detected� The Tracing Line Distortion Response
makes the Tracing Line appear fuzzy when distortion is
present� The fuzzier and more spread out the Tracing
Line is, the greater the distortion�
You can set the Tracing Line Distortion Response to
high "H," medium "M," low "L" (default), or "OFF�" Set the
Tracing Line Distortion Response to high to increase its
sensitivity to distortion�

Note: To change the Tracing Line Distortion Response
sensitivity settings, refer to the Customizing Display
Elements section.
When the Distortion Line is enabled, the tracing line fuzz‑
iness is turned off� The Tracing Line becomes a solid line
and the Distortion Line (dashed line) appears when dis‑
tortion is present� The dashed Distortion Line represents
the signal detected by the Upper Antenna and the solid
Tracing Line represents the signal detected by the Lower
Antenna�
Distortion is likely if the Distortion Line does not align
with the Tracing Line� The Distortion Line and the Tracing
Line may move randomly if the SR‑24 receives a weak
signal�
