Depth

CAUTION
For the depth to display correctly, the mode must be
set correctly. Sonde frequencies and Line Trace fre-
quencies can sometimes be the same. Make sure the
mode icon next to the frequency that you are using,
is the mode you intend to be locating with.
The SR‑24 calculates measured depth by comparing the
difference in Signal Strength between the Upper Antenna
and the Lower Antenna� The measured depth indicator is
displayed in the lower left corner of the screen in either
meters or feet�
Note: Refer to the Units of Measurement section for in-
structions on how to change the depth units.

Depth Verification Test

To verify the SR‑24 is correctly measuring the target
line's depth, follow these steps:
1� Touch the Lower Antenna to the ground directly
above the Sonde or the target line�
2� Vertically orient the antenna mast and note the
depth�
3� Raise the SR‑24 off the ground approximately
150 mm [6 in]�
4� Observe the change in measured depth� The mea‑
sured depth should increase by approximately
the same amount (in this example, approximately
150 mm [6 in])�
Note: An unchanging or drastically changing measured
depth may indicate the presence of a distorted field or a
line with very low current.
Use measured depths as estimates only.
NOTICE
Independently verify actual depths be-
fore excavating.

Depth Average

In addition to real‑time depth measurement, the Depth
Average feature is useful when the SR‑24 has variable
depth readings�
The Depth Average is a report that averages real‑time
depth readings from the past 2 to 6 seconds and dis‑
plays the average on screen inside the Active View Area
when prompted�
To create a Depth Average Report, follow these steps:
1� Press and hold the Select Key
2� Wait for the countdown screen to go out of view and
for the SR‑24 to beep once�
3� The Depth Average Report shows the measured
depth, angle, and current of the target line�
4� Press the Select Key
al‑time depth reading�
