reset
Analog input Mean goes to value 0 for the duration of the applied reset signal.
The stored values are deleted.
Example:
ValNo = 5 output Mean at reset:
x
1
=xxxxx
Detection that no valid values are available is made. Value 0 is output at output y1.
ValNo = 5 1st sample after reset:
x1= 55 x x x x
Detection that only one valid valid value is available is made. The only valid value y1 = 55 is available at output y1.
ValNo = 5 2nd sample after reset:
x1= 44 55 x x x
Detection that two valid values are available is made. The mean value of these valid values y1 =49,5 is output at out
-
put y1.
After all memory cells with a value are occupied (ValNr = 5), with every sample a new input value is added, the at this
time oldest value subtracted and the result divided by ValNr. = 5. The input values are shifted (like with a shift register).
Inputs/outputs
Digital inputs
disabl
The disable input interrupts sampling
reset
The reset input clears the memory and resets the mean value to 0.
sample
A positive flank (0 r 1) is used for sampling a new value.
Analog input
x1
Process value, of which the mean value is formed.
Digital output
ready
Display for an elapsed overall cycle
Analog output
Mean
Calculated mean value
