4.4.1 Determining the depth automatically
If automatic depth measurement is set, the depth is displayed as
soon as the receiver is located above the location object.
If the receiver is not located above the location object, no value
is displayed for the depth.
Note:
In the case of very uneven surfaces, it is not always possible for
the device to determine the depth, however in such cases it is
always possible to determine the depth manually.
4.4.2 Determining the depth manually
If manual depth measurement is set, the depth key needs to be
pressed until the unit emits a beep.
4.4.3 Determining the offset depth
In addition to simple depth measurement, the so-called offset
depth can also be calculated. In this case, the device also de-
termines the distance to the location object as well as its depth.
This function is useful if
●
obstacles above the line in question prevent a direct depth
measurement
●
the plausibility of results for a simple depth measurement
should be checked
The offset depth is determined by triangulation. The display
shows the following:
● the distance X from the receiver to the location object
● the depth D of the location object
