Fct. 1.06 Upper
Dead Zone
(UP DZ)
Specifies the distance from the
sensor mounting in which no
measurement takes place. Preset
based on sensor type and typi-
cally not edited.
May be of use to minimize re-
flections from mountings not in
conformance with recommended
practices.
Must be set above URV (level
or volume) or LRV (distance) to
achieve full 4 - 20 mA range.
When level is tracked into the
Upper Dead Zone the output
will change to the error current
specified in Fct A.09, Near Zone
Output, and remain there until
level falls backs into the measur-
able range.
NOTE: If the system is powered
on or “signal acquire” is activated
with the level in the Upper Dead
Zone, it will not be detected and
an erroneous reading may result.
