11.3 CSAMT PROGRAM OPERATION
MENU 1:
In all of the following menu descriptions, the bold fields in the boxes are the parameters
that can be changed by the operator.
The
key is active.
CSAMT 0537. Program name and version.
15 Mar 98. Date.
08:53:10. Time.
Grounded. There are two choices for Electric field sensors:
Grounded AMT
Insulated ISL
The grounded configuration is the standard option, while the insulated configuration is
included with this program as a research tool. Our field testing to date indicates that E-field
magnitudes measured with the insulated dipole are one-half the values measured with a
grounded dipole.
When the insulated dipole option is selected, the E-field values are adjusted by a factor of
two to make the resistivities identical between the two methods.
Gain Mode. The default mode is "Noisy", which limits the gains to obtain a
maximum voltage of 1.0 Volts, leaving sufficient voltage range for SP drift and random noise
spikes. The other option is "Standard", which adjusts the gains for a maximum voltage of
3.0 Volts. See Section 6.
Units. The operator can select meters or feet. The default is meters.
