Linear Gain
As described in Section 5.3.6, the weak signals must be amplified or “gained” to see
them on the display. The Gain button described in Section 5.3.6 can be set to a value
from 1 to 9 depending on the amount of gain required (1 is lowest gain, 9 is highest
gain).
There is also a second level of gain available to the user and that is the Linear Gain
setting. The default Linear Gain setting of 2.5 is usually adequate for most ground
conditions, however, if the user finds that they are surveying in areas where high Gain
button settings are always required to see data, it may be advantageous to increase the
Linear Gain setting. Conversely, if the user finds that low Gain button values work to
see the data, it may be useful to decrease the Linear Gain setting.
The choices available for Linear Gain are:
1) 0.0
2) 0.5
3) 1.0
4) 1.5
5) 2.0
6) 2.5
(default)
7) 3.0
8) 5.0
