(3) warming up the transducer for 3 minutes
(4) using output monitoring meter V1 to measuring the output of signal power
source instrument, set a any input value which is within the measuring range of
the transducer Ur. (for e.g. if input value is 100V, the output is 4-20
mA
, the
expected output value Iz should be calculated as:
Iz = (20mA－4mA)×Ur/100V＋4mA
(5) using output monitoring meter V2 to measuring the output voltage U0 of the
transducer, the basic introduced error
γ
of the transducer should be calculated
as:
γ= (Uo－Iz×250Ω)/ [(20mA－4mA)×250Ω]×100
(6)
Repeating (4) (5), if calculated absolute value is less than the given accuracy
value of the transducer, it shows the transducer’s accurate grade is qualified.
