the signal source and give an arbitrary input value Ir within
the range of the sensor. Assuming that the input
specification of the sensor is 1A and the output
specification is 5V, the theoretical output value UZ of the
sensor is calculated by the following formula :
Uz = 5V×Ir/1A
(5)
Use the output monitoring table V2 to measure the voltage
output value U0 at the output end of the sensor, and the
basic reference error γ of the sensor is calculated as
follows:
γ
= (U0
－
Uz)/5V

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.
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.
Don’t dismantle the product, and carry with care to avoiding
bump and fall of the product;
4.
If the product has been using under the environment with strong
magnetic field interference, please pay attention to the shield of
input wire, and the output signal wire should be as short as
possible. For product intensive installation, the space between
each product should not be smaller than 10mm.
5.
Only use identified terminals.
6.
There is no lightening strike prevention circuit design in this
product. For out door and hazardous environment using, please
add protective alternatives.
7.
This product uses fire prevent ABS crust, its temperature
withstand is only limited as +85 ℃, higher than this limitation
will cause the product deformation. Please use and store
carefully.
