Measurement Parameters Menu
Depth defines the length of the radargram vertical scale. This is
sometimes refered to as the time window length. In this case, the velocity
measuremt is used to calculate the depth window.
Note:
This measurement will vary if the velocity measurement
parameter is changed.
Set to manual or auto (Automatic Gain Control).
Note:
Manual gain activates the
Time Gain
button on the main
screen and allows the user to manually adjust the gain. Selecting
Auto
deactivates the
Time Gain
button on the main screen and the
Controller will apply the highest gain level for the signal to noise
ratio.
Set the velocity based on soil type. Setting the velocity allows the
adjustment of the depth scale for differing soil conditions.
Warning:
This is a critical setting if accurate depth information is
required. Soil conditions can vary rapidly with location and all depth
information must be used with caution.
Tip:
The velocity can be set during the post processing stage;
it is not critical that this measurement is established during the
data collection stages, unless marking the depth on site
