5. Observe the system response to the simulated values and make any appropriate changes to the
transmitter configuration or to the system.
6. Modify the simulated values and repeat.
7. When you have finished testing or tuning, disable sensor simulation.
10.1.1 Sensor simulation
Sensor simulation allows you to test the system or tune the loop without having to create the test conditions
in your process. When sensor simulation is enabled, the transmitter reports the simulated values for mass
flow, density, and temperature, and takes all appropriate actions. For example, the transmitter might apply a
cutoff, activate an event, or post an alert.
When sensor simulation is enabled, the simulated values are stored in the same memory locations used for
process data from the sensor. The simulated values are then used throughout transmitter functioning. For
example, sensor simulation will affect:
• All mass flow rate, temperature, and density values displayed or reported via outputs or digital
communications
• The mass total and mass inventory values
• All volume calculations and data, including reported values, volume totals, and volume inventories
• All mass, temperature, density, or volume values logged to Data Logger
Sensor simulation does not affect any diagnostic values.
Unlike actual mass flow rate and density values, the simulated values are not temperature-compensated
(adjusted for the effect of temperature on the sensor's flow tubes).

10.2 Enable or disable software write protection

When enabled, Write-Protection prevents changes to the transmitter configuration. You can perform all
other functions, and you can view the transmitter configuration parameters.
Write protection is enabled by toggling the physical write protect (dip) switch (identified by a lock icon)
located behind the display module.
