claim
The information in the safety claim of the equipment documentation is intended to ensure that
equipment is properly installed in order to maintain it in a condition.
It is assumed that everyone who will be associated with the equipment will be familiar with the
contents of that safety section, or this safety guide.
When electrical equipment is in operation, dangerous voltages will be present in certain parts of
the equipment (e.g. the input terminal). Failure to obverse warning notices, incorrect use, or
improper use may endanger personnel and equipment and course personal injury or physical
damage.
Before working in the terminal strip area, the equipment must be isolated.
Proper and safe operation of the equipment depends on appropriate shipping and handling, proper
storage, installation and commissioning, and on careful operation, maintenance and servicing.
The op erating manual for the equipment gives instructions for its installation, commissioning, and
operation. However, the manual cannot cover all conceivable circumstances or include detailed
information on all topics. In the event of questions or specific problem, do not take any action
without proper authorization. Contact the appropriate WB technical sales office and request the
necessary information.

1. The product h as adopted structure compliance with EN50022; suitable for DIN rail
mounting NS35/7.5, NS35/15. Installation steps are as following (please reference to
dimensional drawing):
Step 1: Immobilize one side of product ‘ s mounting trough to the DIN mounting rail;
Step 2: P ull out the spring clasp;
Step 3: P lace whole mounting trough to the DIN mountin g rail properly;
Step 4: Release spring clasp to make sure the installation.
2. The product has calibrated before out of factory. After correct ly wiring, it can be
powered and used immediately. But for further precis e signal sampling , user need to
warm-up the product for 3 minutes before use.
a) the auxiliary power requires isolation voltage ≥ 2000V
AC
, DC current output ripple
＜10mV .
b) W hen transducer measuring voltage exceed 1000V, it needs dividing input voltage
by using resistor which is provided by Weibo electronic. D ifferent transducer uses
special resistor.

c) Measuring voltage ≤ 600V, uses terminal 3 and 1 ;
d) Measuring voltage ＞600V, uses terminal 3 and 4 ;
3. basic testing method for accuracy
(1) According to the terminal definition table to connect the testing circuit;
(2) T he testing must to be done by under the following conditions ；
A uxiliary power: 24V ±1％， ripple ≤5mV
A mbient temperature: 25 ℃± 2℃
Relative humidity : RH(45
～
75)
％
Accuracy for Signal P ower Source instrument: 0.05
(3) warming up the transducer for 3 minutes
(1) U sing 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 Ir. (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
(2) U sing output monitoring meter V2 to measuring the output voltage V0 of the
transducer, the basic introduced error γof the transducer should be calculated
as:
γ = (Vo － Iz × 250 Ω )/[(20mA － 4mA) × 250 Ω ] × 100
(4) 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.
