The Rules for Custom Linearization:
• The difference between any consecutive
values in the table (in either column) must be
less than 50% of the entire configured range.
• One “Output EGU” value per “Input mV” value
only.
• It is not necessary to use all 85 available
points, but the first and last points in the curve
always default to the 0% and 100% input
scale (input range).
• If you decide not to use all 85 points, you must
change the number of points in the “Points”
field to the number you wish to use.
Note:
Moore Industries suggests filling in the EGU
(Engineering Units), then the number of points, and
finally the values in the table.
9. When the table is complete, click on the
“QuitTabl” button and answer “Yes” on the pop-
up dialog box.
10. Click on the “Prog” (Program) button to
download the output trim settings into the
transmitter memory.
CAUTION
:
Any time a connected TDY is “programmed”
by downloading a Configuration File into memory,
ALL of the configuration parameters resident
in the transmitter memory at the time of the
download are OVERWRITTEN.
This includes things like: tag name, calibration date,
trim values, etc.
Once a transmitter’s memory is “erased”
in this fashion, the old operating parameters
are unrecoverable, and will have to be
regenerated from scratch if needed again.
