By pressing (under the RHO label), the following is displayed:
Display "B"
rho. This column displays the apparent resistivity in ohm-meters for each channel defined as
an E-field channel (Ex, Ey) that has a matching orthogonal H-field channel (Hy, Hx). If the E-
or H-field being measured on a particular channel does not have a corresponding orthogonal
component (such as Hz, or Ex without a corresponding Hy), the value displayed will be the
magnitude of the received signal in volts with the magnitude calibrates in Freq Domain Cal
removed. For channels defined as H-field inputs, (Hx, Hy, Hz), the coil magnitude calibrates in
Antenna Cal are also removed.

. This column displays the phase difference in milliradians for each channel
defined as an E-field channel (Ex, Ey) that has a matching orthogonal H-field channel (Hy,
Hx). If the E- or H-field being measured on a particular channel does not have a
corresponding orthogonal component (such as Hz, or Ex without a corresponding Hy), the
value displayed will be the phase of the received signal in milliradians with the phase
calibrates in Freq Domain Cal removed. For channels defined as H-field inputs, (Hx, Hy,
Hz), the coil phase calibrates in Antenna Cal are also removed.
By pressing again (now under the MAG label) the operator will recall Display A. In
whichever position the display is left, it will remain in that position for subsequent data
acquisition, until changed again by the operator.
