Accuracy for signal power source instrument:
0.05
(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 0V-5V, the expected output value Uz should be calculated as:
Uz=5V
×
Ur/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= (Uo
－
Uz)/5V×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.
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.
The product only be used for testing the AC wave shape that with low harmonic wave.
4.
Don’t dismantle the product, and carry with care to avoiding bump and fall of the
product;
5.
If the product has been using under the environment with strong Electromagnetic field
interference, please pay attention that the output signal wire should use shielded wire.
And double-pointed of the shielding layer should be connected with protective earth.
For product intensive installation, the space between each product should not be
smaller than 10mm.
6.
Only use identified terminals.
7.
The input that be given by the product tab means the virtual value of the AC signal .
8.
There is no lightening strike prevention circuit design in this product. For out door and
hazardous environment using, please add protective alternatives.
9.
when the transducer’s
input exceeds the rated input, the output of the transducer will
exceed the rating. If this condition isn’t expected, you can increase a protective circuit
to restrict the extent at the fan-out of the transducer.
10.
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.
11.
please do not destroy or change the product label, symbol, and do not disassemble the
sensor, or else we will not provide the product warranty.
