Example 2:
Formula: I.FS.H value without decimal points = (Desired value on display after 1 hour * 14062.5)
-----------------------------------------------------------------------
(Total value accumulated after 1 hour/256)
Example: A 4-20mA input signal must corresponds to a 0-100 displayed rate value. The input signal must be totalised over an hour.
The reading at 20mA must be 360 after an hour.
According to the formula:
A = Desired value on display after 1 hour
B = I.FS.H Value without decimal points
C = Total value accumulated after 1 hour (i.e Max value on rate (100) * 3600 seconds = 360 000 )
B = (A * 14062.5 )
-----------------------
(C/256)
Therefore B = ( 360 * 14062.5 )
-------------------------
(360 000/256)
I.FS.H .= 3.600
After 1 hour at 20mA, the display should show 360.
Under the P.Int sub-menu in the instrument, set as follows: select: 4-20; P dP = oooooo; ZEro = 000000; P FS = 000100; P.Filt = 00.5;
incr = 000; C dP = oooooo; I.FS.H = 3.600
