The test procedure is simple:
. Firs of all, supply the converter and measure the zero input
current (nominally 4 mA).
. Next, select values to be generated; compute the
corresponding current measurement, and prepare a calibration
table.
. Next, generate the selected parameters, measure the
reading, report it to the table and compute the converter
error.
For instance, you want to test a current converter with the
following characteristic:
I0 = 4 mA; I100 = 20 mA.
From this, the nominal output current as a function of the
input current is:
Iout = 4 + Iin * (20-4)/100 = 4 + 0.16 * Iin
