Computer connects.
Input and the output of this utility model measure loop use air plug connected mode, use and calculate
Machine control relay in relay control unit with control the connection on each detection branch road with
Disconnecting, the size of current that detects in detection branch by the sensor 1 for detecting electric current also passes
Transport to computer judge；Relay coil controls the board control mode of employing standard.
This utility model do not work (not accessing 28VDC) state under, insure intact, input
It is conducting with exporting corresponding branch road.28VDC is accessed in wiring harness test loop, and each road is flow through
The size of current value, can be controlled card by computer and be read out.Wiring harness test loop can be by calculating
Whether machine is controlled work, if controlling as under duty, loop disconnects.
The reduction formula of loop current: I=V × 1000/500 (I is the current value that loop is flow through,
Unit: A；V is the voltage tester value in loop, and unit is V).
This utility model in actual use, using if being only used as loop, not monitoring and flowing through
Current value, the cable of power supply, test cable and control relay can not connect.If desired
The current value that test is flow through, connects the cable power of power supply, test cable and control relay
Good, to power source (+28VDC), connect the on and off switch on the front panel of wiring harness test loop,
The current value on each road of current value is read by computer software.If desired a certain road is disconnected,
By computer software control relay control unit.As tested the current value of the first via, computer
Software reads the value of the first via；Computer software control first via relay J 1 works
Disconnect the relay contact J1 of the first via.(i.e. shut down) after measure loop runs, by face
On plate " on and off switch " is got to open position, is closed end power supply.
