Calibration
The T-5220 has a fixed span
and is factory calibrated. The
only adjustment necessary is
when shifting the span for
special applications or fine
tuning the instrument.
1. Accurately measure the
temperature at the element.
2. From the graph above, find
the proper transmission
pressure corresponding to
the measured temperature.
Be sure to use the vertical
scale on the graph which
matches the range of the
transmitter.
3. Turn the span adjusting
screw until the output
pressure corresponds to the
temperature at the element.
The test connection for the
output pressure on the
transmitter is at the
hypodermic needle test
point.
Note: To achieve the highest
degree of accuracy for a
given application, calibrate
the T-5220 at the midpoint of
the actual operating range.
