(3) Warming up the transducer for 3 minutes
(4) Using output monitoring meter V1 to measuring the output of signal power
source instrument, set any input value which is within the measuring range of
the transducer Vr.(e.g. if input range is 100V, the output is 0-5V ). the expected
output value Vz should be calculated as:
Vz=5V×Vr/100V
(5) Using output monitoring meter V2 to measuring the output voltage V0 of the
transducer, the basic introduced error
γ
of the transducer should be calculated
as:
γ= (Vo－Vz)/5V×100
(6)
Repeating step (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.
