Use
1 Wiring Method:
(1)1/4bridge Wiring(Mode 1)
To compensate for side "B" terminal at the copper off, With a wire connection from work side "Vi-" terminal and the compensate for side "D" terminal, Channel work side "Vi +" at the push of copper,The work piece receiving work side "+ Eg" "Vi +" side.
 
(2)1/2bridge Wiring(Mode2):
       Work with a wire connection terminal "Vi-" and the compensation side of the terminal space, Compensation at the end of copper into the terminal space, Work Terminal "Vi +" at the push of copper, The working end "+ Eg" "Vi +" then the work piece, Compensation side "A", "B" received compensation piece.
 
(3)1/2bridge Wiring(Mode3 and Mode4):
     Strain gauge wiring: Work with a wire connection terminal on "Vi-" terminal to the compensation terminal on the "D" terminal; Work side-side and compensate for all the copper off, The working end of the "+ Eg" and "Vi +" then a work piece; The working end "Vi +" and "-Eg" take another piece of work.
Sensor wiring:Work with the wire end of "Vi-" and the compensation pin "D" side connection;
Work off all the copper side and compensation, The half-bridge sensor "is the power input" received the instruments of the "+ Eg" on; "Negative power supply input," received the instrument "-Eg" on;
 
 

(4)Full-bridge Wiring(Mode5 and Mode6):
    Strain gauge wiring: To work off all the copper side and compensation, The working end "+ Eg" and "Vi +", "Vi +" and "-Eg", "-Eg" and "Vi-", "+ Eg" and "Vi-" all by one strain gauge.
 
Sensor wiring: To work off all the copper side and compensation, The full-bridge sensor "is the power input" received the instruments of the "+ Eg" on; "Negative power supply input," received the instrument "-Eg" on; "Is the signal output," received the instrument of "Vi +" on; "Negative signal output terminal" connected equipment "Vi-" on;
  
2 Voltage test:
     To work off all the copper side and compensation, "Vi +" positive signal input terminal,"Vi-" negative signal input terminal, The software is set to voltage input.

4  Software operation process
 
Road type
 Bridge type refers to the strain in the bridge, Depending on the test conditions, Strain gauge and the number of different ways.
 

No.	Name and purpose	Field examples
Mode 1	1/4 bridge For measurement of simple tension or compression bending strain
Mode 2	1/2 bridge(A work piece,A compensator) Suitable for harsh environments than the simple measurement of tension or compression bending strain
Mode 3	1/2 bridge(Two work piece,) For large changes in ambient temperature measurement in case of simple tension or compression bending strain
Mode 4	1/2 bridge(Two work piece,) For measuring bending strain only, eliminating the tensile and compressive strain
Mode 5	Full-bridge(Four work piece) Only measured for tensile and compressive strain
Mode 6	Full-bridge(Four work piece) For measuring bending strain only
