(5) Using output monitoring meter V2 to measuring the output voltage Uo of the
transducer, the basic introduced error
γ
of the transducer should be calculated as:
γ
= (Uo
－
Iz×250
Ω
)/[(20mA
－
4mA)×250
Ω
]×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.
Caution:
1.
Pay attention to the auxiliary power information, especially the auxiliary power grade, and
polarity, other wise will damage the product.
2.
pay attention to the wire connection; wrong terminal connection will cause malfunction of the
product and even damage the product;
3.
