LOOP CHECKING SIMULATION
When the HS3-SCK is ordered, 3
fi
xed output sensors will be provided. These sensors
can be identi
fi
ed by the blue cap.
Figure 27
Sensor Simulator
Each sensor is factory set with a RH and T output. The 3 supplied will be:
25% @ 23°C (73°F)
50% @ 23°C (73°F)
75% @ 23°C (73°F)
These simulators can be connected to a signal loop and used to check its functionality
and accuracy.
5.1 Simulator
Connection
A probe electronics assembly is provided with the Simulator Kit.
A sensor simulator module can be connected to the probe in the same manner as a
sensor. See Section 4 for detailed instructions.
The simulator and probe assembly can then be connected to the loop which requires
testing.
5.2
Checking /Programming the Simulators
The application software can be used to change the output range of any of the sensor
simulators. Ensure that the simulator to be re-ranged is attached to a probe, then
establish communications with the software as per the instructions in Section 3.3.
Section 3.7 details the functionality within the Application Software for re-ranging the
simulators.
