(2) Device Variable Simulation Function
Using the simulation function, the output signal can
be confirmed 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.
• Procedure of device variable simulation
Step 1 Call up the
parameter
[Root Menu] → Diag/
Service → Test → Simulate
2 Selection of

NOTE
• All the simulations for differential pressure,
static pressure and external temperature,
are reflected to the output. Accordingly,
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.
(3) Squawk
This feature can be used to identify the
communicating transmitter by remotely causing
LCD to display the particular pattern as shown in
the Figure 3.3.
“SQUAWK” continues for approximately 10
seconds, then is released automatically.
• Procedure to call up the Squawk display
[Root Menu] → Diag/Service → Test → Squawk
