TESTER

This is one of the most important tools for repairing, like on Electronic Repair, tester is the way to analyze the Circuit if it is short of low on contact. Electronic test equipment (sometimes called "testgear" or "bench top") is used to create signals and capture responses from electronic Devices Under Test (DUTs). In this way, the proper operation of the DUT can be proven or faults in the device can be traced and repaired. Use of electronic test equipment is essential to any serious work on electronics systems.

There are two kinds of Tester, the one is Digital and the One is Analog.
