Electronics verification
To verify a 4–20 mA output
For a given input frequency F (Hz), and K-factor (compensated), find output current I:
where C
x
is the unit conversion (Table C-1 on page C-125), URV is the upper range value (user
units), and LRV is the lower range value (user units).
To verify a special units output
For special units, first divide the special unit-conversion factor into the base unit factor C
x
.
C

= C

/sp. units conv. factor (Table C-1 on page C-125).
