Displays the echo stem plot for the selected Duration. Use this
display to check that the radar pulse is measuring accurately.
Example: Echo stem plot for 2 liquid interface:
X axis: The Reference plane is at 0. Distance is in Length Unit.
The above image the distance is measured in meters.
Resolution: 1 pixel = 1 meter (as in the above image)
Y axis: Echo amplitude is in terms of counts. The Range is -40,000
t0 +40,000 which is represented as -4C to +4C.
Where:
C = Counts
L = Distance to product
I = Distance to interface
E = Distance to end of probe
Resolution: 1 pixel = 2000 counts
Display Error Handling:
"-----": In the distance field indicates the respective distance
(product or interface) status is Bad.
"?????": In the distance field indicates the respective distance
(product or interface) status is Unknown.
In the above example, the distances measured by the echo are:
Top liquid: @25m, Interface (bottom liquid): @45m
The display updates periodically.
