Example 1:
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 correspond to a 0-2500 rate display. This input must also be integrated (totalised) over an hour.
The totaliser must show 1250 after 1 hour if the input is 12mA for that hour. For calculation purposes, calculate the totalised value at
20mA, which in this case will be 2500.
According to the above 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 (2500) * 3600 seconds = 9 000 000 )
B = (A * 14062.5)
--------------------
(C/256)
Therefore B = (2500 * 14062.5)
------------------------
(9000000/256)
I.FS.H = 1.000
After 1 hour at 12mA the display should show 1250. After 1 hour at 20mA, the display should show 2500.
Under the P.Int sub-menu in the instrument, set the following: select 4-20; P dP = oooooo; ZEro = 000000; P FS = 002500;
P.Filt = 00.5; incr = 000; C dP = oooooo; I.FS.H = 1.000
