Select or enter a parameter for each user programmable field. User programmable fields unique
to TDIP are:
Array Type
Select one of the seven array types using the
Home
SELECT UP
and
SELECT DN
End
keys:
Dipole-Dipole D-D
Pole-Dipole P-D
Schlumberger Sch
Gradient Grd
Pole-Pole P-P
Downhole D-H
Core Sample LAB
If Gradient or Schlumberger arrays are chosen, then two additional lines, Ax
location and Bx location, appear on the menu. These are the transmitter current
electrode locations.
If the Downhole array type is chosen, resistivities will not be calculated or displayed.
The Core Sample selection provides for input of cross-section area (in square centimeters)
and length of core samples (in centimeters) to get correct resistivity values in ohm meters. After
continuing to the Data Acquisition Screen, press
to input the length and area and the
current monitoring shunt resistor values. Refer to the CR Survey Program for more information.
