Further, switch is arranged on the 3rd connecting line.
Further, the battery is 9V dry cells.
Compared with prior art, the present invention has following beneficial technique effect：
The present invention connects electronic odometer sensor with detection wire harness when being detected to electronic odometer sensor
Connect, open switch, be that can determine whether whether sensor damages according to the situation of first voltage table and second voltage table, use is very simple
Just, personnel after sale can be effectively helped to judge the quality of transmission sensors.
Further, the instruction of tester first voltage list index should (electronic odometer sensor signal be high between 5-10
Level state), second voltage list index indicates to be less than 1 (electronic odometer sensor signal low level state), by tested electronics
Kilometer sensor induction end and other irony objects Rapid contact, the list index alternatively swinging of tester two, and amplitude of fluctuation repeatedly
Value is essentially identical (high and low level state is alternately changed), then illustrates that electronic odometer sensor is not damaged, if two pieces of voltmeters
The performance of pointer is not inconsistent with above-mentioned, then is tested electronic odometer sensor failure, operation is simple.
