RECALIBRATING FACTORY STORED VALUES
The following list outlines conditions that are unique to factory recalibration:
G Rail Installation
style DIN rail, angle the module
so that the upper groove of the
“foot” catches under the lip of the
top rail. Push the module toward
the rail until it snaps into place.
To remove a module from the
rail, push up on the bottom of the
module while pulling out and
away from the rail.

must be taken to insure the selected range extents are not exceeded. The
minimum scale and full scale calibration values must be set to the extents
of the range being calibrated.
For example: If the Input Range DIP switches are set for the 4-20 mA
output range. When calibrating the input voltage range, it is recommended
that a range above 1 V be used to provide better accuracy.

set the remaining DIP switches for the range to be calibrated. Note: Be sure
to change the terminal wiring to match the Input or Output range DIP
switch settings before performing the calibration procedure. Set calibration

20 mA.
according to EN50035 - G32 , and top hat (T) profile rail according to EN50022 - 35 x 7.5 and 35 x 15. The unit should be installed in a
location that does not exceed the maximum operating temperature and provides good air circulation. Placing the unit near devices that
generate excessive heat should be avoided.
The unit is equipped with a universal mounting foot for attachment to standard DIN style mounting rails, including G profile rail
WARNING: Read the complete procedure at least
once before attempting to recalibrate the factory
values. This procedure should only be performed
due to factory checksum error or unacceptable
error. This procedure should be performed by
qualified technicians using accurate calibration
equipment.

pry upwards on the module until
it releases from the rail.
