Rerange (Set LRV/URV calibration)
(application to level measurement) at
change of level (LRV/URV)
Functions of RERANGE can be made
with FXW Version 6.0 or upward.
When the lower range value (LRV) and
uppeer range value (URV) need to be
adjusted again during measurement of
tank level, the measurement levels can
be changed at the same time by setting
the LRV or URV to be adjusted from
FXW.
Apply an input pressure required for
rerange of LRV at display of 3 and
press ENT twice.
In this way, the rerange of LRV is com-
pleted, then the new measurement
range LRV and URV, which conforms
to the actual input pressure, is dis-
played.
When rerange is made at a point other
than 0%, input the set value (PV%) of
that point at display of 3 , and press
ENT at display of 4 while applying a
corresponding pressure. In this way,
the measurement range can be changed
to the input corresponding to that pres-
sure.
Apply an input pressure required for
rerange of URV at display of 6 and
press ENT twice. The rerange of URV
is completed, then the new
measurement range LRV and URV
corresponding to the actual input pres-
sure is displayed. When rerange is
made at a point other than 100%, input
the set value (PV%) of that point at dis-
play of 6 and press ENT at display of
7 while applying a corresponding pres-
sure. In this way, the measurement
range can be changed to the input cor-
responding to that pressure.
Note)The unit of LRV/URV at 5 and 8 are
displayed in theunit selected by Menu No.

(Ex)
In case of the actual scale specification with a digital
indicator provided, if the range is changed, indicator
display might not match. So, setting is required again
in response to the display in the digital indicator
(G:XMTR DISPLAY).
In case of the actual scale specification with an analog
indicator provided, if the range is changed, the scale
for indicator might not ensure exact reading.
When CHNG is pressed at display of 1, the following
is displayed.
This means that RERANGE cannot be made because
MENU No. H: LINEARIZE is set in EFFECTIVE.
In this case, press the CL key and set in INVALID on
the panel of No. H: LINEARIZE.
