Available Ranges

As specified in Table 1-1, the transmitter has 10 ranges. Depending upon the range,
the transmitter can measure temperature span as narrow as 180°F or as wide as
1000°F. A multi-turn, top-accessible potentiometer provides fine span tuning. A
second top-accessible, multi-turn potentiometer provides a zero adjustment which
allows placement of the 4-mA output temperature /- 25% for Fahrenheit and
+/- 10% for Celsius of nominal span (refer to Section 3.0, Calibrating the Transmitter,
for more details). Models TX92A-*-L are transmitters with the 4-20mA output
linearized to temperature.
