[Service only item]
If this variable is set to zero (default), the gauge will
adjust the voltage gain of the I.F. (audio) signal
automatically based on the ROI, and dielectric
constant of the process material. If it is set to a non-
zero value, this value is used to override the
calculated gain setting.

Material in tank
is water based
Change to “is not”→→
NEXT↓↓
This entry selects one of two default (assumed) values
for the dielectric constant of the process material,
which in turn sets the initial gain for the microwave
signal. In most applications, selecting “water based”
or “not water based” is adequate to set the gain. If you
know the dielectric constant for your process
material, you can enter it in the next menu item.
Note: If your application involves more than one
process material with different dielectric
constants, enter the highest dielectric
constant.
Direct Entry Code: ‘025010’
Dielectric constant
of process 0.000
(presently 80.00)
NEXT↓↓
The “presently” assumed value is used for the
dielectric constant of the process material unless you
enter a non-zero value here. The assumed value is
80.00 if you selected “is water based” in the previous
menu item, or 4.704 if you selected “is not water
based.”

flange mounted seal
NEXT↓↓ CHANGE→→
Select “antenna without flange mounted seal” for an
intrusive sensor mounting configuration or change to
“antenna with flange mounted seal” for the isolation
sensor configuration.
