Abstract

The present invention specifically relates to a tester for testing 220V load and DC voltage, comprising: an AC isolation circuit for connecting to 220V AC and implementing electrical signal output; a test load and a voltage circuit, and the AC isolation circuit is connected to the test load and Voltage circuit, test load and voltage circuit according to access load and voltage, and output test results; test load and voltage circuit includes the first single-chip microcomputer PIC1, the second single-chip microcomputer and PIC2 and the third single-chip microcomputer PIC3, 1 pin of the first single-chip microcomputer PIC and Pin 1 of the second single-chip microcomputer is connected, and the first single-chip microcomputer PIC is connected with the switching acquisition circuit 202 and the first joint J1, and pin 1 of the second single-chip microcomputer is connected with the first joint J1; the third single-chip microcomputer PIC3 is connected with the load working state display circuit and the load Connector J3. The beneficial effects of the present invention are: the present invention can replace human eye observation through the combination of test load and voltage circuit, guarantee production quality and strong versatility, and reduce work production cost.

Description

technical field [0001] The invention specifically relates to a tester for testing 220V load and DC voltage. Background technique [0002] At present, each set of FCT test tooling needs to install 2-8 outsourced voltage acquisition modules, and excessive use of outsourced voltage acquisition modules results in waste of cost. In addition, employees need to observe the display of the voltage acquisition module and judge the results during the operation process. Employees tend to ignore the voltage and voltage range during the operation process, and even voltage testing, which may cause product hazards. In addition, employees should observe whether the load light is on while observing the voltage and other actions. More employees need to observe the output of the load light during the operation process. They think that there are too many judgment factors and the reliability of the test is poor. There are also two types of tooling and load lamps: integrated and separate, resulti...

[0002] At present, each set of FCT test tooling needs to install 2-8 outsourced voltage acquisition modules. Too many outsourced voltage acquisition modules are used, resulting in waste of cost

In addition, employees need to observe the display of the voltage acquisition module and judge the results during the operation process. Employees tend to ignore the voltage and voltage range during the operation process, and even voltage testing, which may easily cause product hazards.

Furthermore, employees should observe whether the load light is on while observing the voltage and other actions. More employees need to observe the output of the load light during the operation process. They think that the judgment factor is the light output. They think that there are too many judgment factors and the test reliability is poor.

There are also two types of tooling and load lamps: integrated and separate, resulting in complex types of tooling structures and no uniform standards
