Abstract:
1. A test circuit for testing a flexible printed board (FPC), comprising: a parameter preset module, configured to preset a parameter range indicating a suitable range of the resistance value of the FPC, and further configured to connect to the FPC and convert the resistance value of the FPC to a related parameter, wherein, the parameter preset module comprises a power port, a reference resistor, a first potentiometer, and a second potentiometer, the power port provides a first voltage by connecting to a power source, the first potentiometer and the second potentiometer are connected in parallel between the power port and ground, a terminal of the reference resistor is connected to the power port, and the other terminal of the reference resistor constitutes an incoming terminal for connecting to the FPC; a comparison module, configured to compare the related parameter with the parameter range, and produce a comparison result; and a prompt module, configured to produce a corresponding prompt signal according to the comparison result.
