Azbil Corporation Functions, Configurations, and Structures of model JTD720A and communicator
Model JTD720A - Smart Multivariable Transmitter 1-3
INPUT mode:
When the simulated value (DP,PP,TP) is input, displays the compensated output in %
or engineering unit.
Sub display
Measurement mode
Displays the liner/square root , engineering unit, process pressure, and process
temperature(only connected with RTD).
It has three display modes.
LIN:
Both output and display is linear
DSP : Output is linear, display is square root(Flow rate)
OUT : Both output and display is square root(Flow rate)
~Note • When the saturated steam compensation (Options code:F2) is selected,
@ is displayed in the right of °C. It is shown that it is calculated based
on the vapor pressure in piping. So when steam doesn't flow, about
100°C is displayed under the atmospheric pressure condition .

Calibration mode
Differential pressure, static pressure or process temperature is displayed according to
the mode. The mode is displayed on the lower column.
DP mode:
