Measuring Depth (Sonde Mode); Clipping (Sonde Mode); Menus And Settings - RIDGID SeekTech SR-20 Operator's Manual

Measuring Depth (Sonde Mode)

The SR-20 calculates Measured Depth by comparing the
strength of the signal at the lower antenna to the upper
antenna. Measured Depth is approximate; it will usu-
ally reflect the physical depth when the mast is held
vertical and the bottom antenna is touching the ground di-
rectly above the signal source, assuming no distortion is
present.
1. To measure depth, place the locator on the ground,
directly above the Sonde or the line.
2. Measured Depth will be shown in the lower left
hand corner of the SR-20's display screen.
3. A Measured Depth reading can be forced by press-
ing the Select Key during a locate.
4. Measured Depth will be accurate only if the signal is
undistorted.

Clipping (Sonde Mode)

Occasionally the Signal Strength will be strong enough
that the receiver will be unable to process the entire sig-
nal, a condition known as "clipping". When this occurs,
a warning symbol will appear on the screen. It means
that the signal is particularly strong.
NOTE! Measured Depth Display is disabled under clip-
ping conditions.

Auto Menu Exit Count-down Timer
While traversing the menu tree, a counter appears at
the bottom of the screen counting down. When it reaches
zero, it will automatically move back up one level of the
menu tree until it reaches the operating screen again. It re-
sets to nine with each key press, or each time it goes up
one menu level, until it reaches the operating screen.
Currently Available Sonde
