Problems solved by technology
There are obvious defects and deficiencies in this method of detecting the electrical parameters of the double-connected potentiometer: first, more testing instruments are required, and most of them are pointer-type testing instruments of pure analog circuits, and the accuracy is low; The testers at each station need to insert the double potentiometer into the special fixture for corresponding measurement, and then pull out the double potentiometer for the next process to continue testing, which seriously reduces the work efficiency; the third is that it requires more labor, which increases the cost for the enterprise. Larger labor cost burden

Description
technical field [0001] The invention relates to the technical field of potentiometer detection equipment, in particular to a comprehensive detector for electrical parameters of a double potentiometer. Background technique [0002] Manufacturers of dual potentiometers need to detect electrical parameters such as total resistance, zero resistance, synchronization characteristics, and dynamic noise characteristics of dual potentiometers on the production line. At present, enterprises test the electrical parameters of the double potentiometer, and most of them use multiple stations to test the different electrical parameters of the double potentiometer separately. For example: the first station detects the total resistance and zero resistance of the duplex potentiometer; the second station uses a synchronous characteristic tester to detect the synchronous characteristics of the duplex potentiometer; the third station uses 2 dynamic noise testers Detect the dynamic noise of the ...
