The top reading indicates % of SPAN, the state of
the valve (OPEN, PARTIALLY OPEN, or CLOSED)
is on the bottom line.
Press the right button to return to the STATUS
menu.

Calibration

To access the Calibration menu press the right

left button (NEXT).
WARNING
During calibration the valve will move
full stroke. To avoid personal injury
and property damage caused by the
release of pressure or process fluid,
provide some temporary means of
control for the process.
In the CALIBRATE menu press SELECT. This will
allow you to select the first calibration point to be
used, either 0% or 100%. Push the left button to
select 100% and the right button to select 0%. The
next display instructs you to set the valve or
monitored piece of equipment in either the 0 or
100% location, depending on the first calibration
point chosen.
Once set, use the left button to toggle the recording
position to MARKED. MARKED indicates that the
location has been recorded; UNMARKED indicates
that position has not been recorded. After the first
position has been MARKED press NEXT to select
the second calibration point (it will be be the
opposite of the first calibration point). Use the left
button to toggle the recording position to MARKED.
Press NEXT to enter the APPLY menu. Select YES
to apply the changes.
During the calibration procedure, the
valve is moved to one position and
MARKED. The valve is then moved to
other end of travel or rotation and the
second position is recorded
(MARKED). Earlier calibration points
can be used or discarded.

Note
Applying calibration points without
changing the valve position will result
in the calibration attempt being
unused or discarded.
The calibration status will be displayed:
SUCCESS—indicates that the calibration procedure
was successful.
SPAN HI—indicates that a problem with the high
end of travel or rotation was observed. Check the
mounting and magnetic array placement and
re−attempt calibration.
SPAN LO—indicates that a problem with the low end
of travel or rotation was observed. Check the
mounting and magnetic array placement and
re−attempt calibration.
ERROR SPAN—indicates that a problem with the
amount of travel or rotation was observed. Either the
travel was too much or too little:
D >10_ or <40_ of rotation was detected for the
rotary array
D Excessive travel >125% was recorded for the
linear array or less than 25% of travel was detected.
D Check the mounting and magnetic array
placement and re−attempt calibration.
Press the right button to exit the calibration attempt,
the display will show UNCHANGED.
