NOTE
The output process value while simulation
can be monitored by LCD and through
communication as follows.
Process value Output value
DP Simulation value according to
simulation mode
SP Simulation value according to
simulation mode
ET Simulation value according to
simulation mode
Flow Rate Flow calculation value using the
DP, SP, ET simulation value
Total Flow Flow Rate accumulation value

If one of the following alarm occurs while
simulation, all of the output data are held to the
value before alarm occurs.

(4) Device Variable Simulation Function
(Effective only when setting to HART 7)
Using the simulation function, the output signal can
be conrmed by setting any value and status to the
selected device variable.
Call up the parameter and follow the message
shown.
After completing the step 5, the simulation starts.
Integral indicator shows output and alarm (AL.91)
alternately.

NOTE
• The ow rate is calculated from differential
pressure, static pressure, and external
temperature, and the total ow is
accumulated from the ow rate. Therefore,
the simulation results for the ow rate and
total ow depend on the simulation settings
of differential pressure, static pressure, and
external temperature. The total ow depends
on the ow rate as well.
• The total ow simulation is only applied for
LCD display and communication output and
does not affect the total ow value.
• All the simulations for differential pressure,
static pressure, external temperature,
ow rate are reected to the output.
Accordingly, the loop current, LCD display,
and communication output are directly
corresponded to the simulate value.
The alarm output is also available according
to the simulate value.
• Damping is applicable for differential
pressure, static pressure, and external
temperature simulation.
