Description

An electrical signal tester

technical field

The utility model specifically relates to an electric signal tester, which belongs to the technical field of electric signal test.

Background technique

With the acceleration of production rhythm, it is more important to quickly judge accidents and find fault points. It is always a problem to quickly judge the given state of various solenoid valves, proportional valves, and servo valves. If a multimeter is used for manual measurement, it is often impossible to start with the multimeter in hand, and the test pen cannot be inserted into the plug of the solenoid valve. The definition of the pin of the proportional valve makes it difficult to distinguish the voltage signal from the current signal, and the slipping of the test lead leads to short circuit, grounding, etc. Such problems not only delay the quick judgment, but may also lead to secondary failures. If a special solenoid valve or proportional/servo valve tester is used, it is not only expensive, but its complicated functions are also difficult for the operator to master, and it is not suitable for rapid testing.
