Step Nine
SIMULATION
This function simulates the 4-20mA current output, when the sensor is configured and installed on the tank, but
the level cannot be changed easily for testing. Percent (of span), Current Output or Distance can be used as
the input method to set the current output.
1) From the Main Screen, press
Enter
to advance into the
Main Menu.
2)
Press
Right Arrow
repeatedly until the arrow is next to
Diagnostics.
3)
Press
Enter
to advance into Diagnostics.
4)
Press
Right Arrow
repeatedly until Simulation appears.
5)
Press
Enter
to advance into Simulation.
6)
Use the
Right Arrow
to scroll among the three simulation
methods (Percent, Current Out or Distance).
7)
Use
Enter
to select the method of simulation.
8)
Upon selection of a method, the simulation will start and the
current output will proportionately reflect the value shown.
While the simulation is running, the value can be changed.
9) Use the
Right Arrow
to move one segment to the right
.
The
Right Arrow
will scroll left to right and then back to the
first segment.
10) Use the
Up Arrow
to increase the value of the number
highlighted. The
Up Arrow
will scroll from 0 to 9 and back
again.
11) When the value is correct, press Enter and the current
output will reflect the value shown.
12) When done, press
ESC
to return to Simulation, press
ESC
again to return to the Configuration Menu, and press
ESC
a
third time to return to the Main Screen.
Percent
Current Output
Distance
This method uses percentage of
span (0-100%) to set the current
output (4-20mA) between the
Empty and Full Configuration
values with 100% equal to 20 mA
and 0% equal to 4mA.
This method directly sets the
current output (4-20mA) to the
desired value.
This method uses distance from
the sensor’s measurement location
to set the current output (4-20mA)
between the Empty and Full
Configuration values.
