8.0 SIMULATION FUNCTION
The simulation function allows the user to check the relationship between the
transmitter’s configured input – in basic electrical units (such as mV or Ohms, etc.)
to the scaled or engineering units (such as °F or °C) – and to its output – (in mA
and %).
The simulation function also is very useful for testing a “Sensor vs. Output” transfer
function when using nonstandard sensor transformations, such as Calender-Van-
Dusen, Polynomial or any other User Defined Table.
The simulation function can be accessed from the main menu by clicking “Device”
and then “Simulation.” Simulation may be done while Off-line or On-line with an
indicator. Enter any one of the four values in the simulation dialog box and the
other three will automatically be calculated.
Figure 15 – Simulation
If communication between the indicator and the PC is enabled, On-line simulation
will be performed. As with Off-line simulation, enter any one of the four values and
the other three will be calculated. Click “Apply” and the indicator will be driven to
the indicated/calculated value. For a continuous dynamic update of the output, the
“Dynamic Link” box must be checked. This can be very useful for checking system
responses to calculated values.
The scroll bar may be used to increase or decrease the transmitter’s output by fixed
amounts. Clicking on the arrows at the ends of the scroll bar changes the output by
1%. Clicking inside the scroll bar changes the output by 10%.
Note: There is a 2-3 delay between calculation and completion of writing to the
indicator.
