Abstract

The invention provides a thermistor electrical property batch automatic test device and a working method. The thermistor electrical property batch automatic test device comprises a test host, a thermistor test box, binding posts and thermistors, wherein the test host is installed and connected with the thermistor test box and the binding post; a plurality of thermistors are allowed to be installed in the thermistor test box, and the thermistors are electrically connected with the binding posts. The device realizes batch automatic testing of the electrical performance of the thermistor, and improves the efficiency of thermistor testing.

Description

technical field [0001] The invention relates to the field of thermistor testing, in particular to a batch automatic testing device and working method for the electrical properties of thermistors. Background technique [0002] In many fields such as modern high-tech military electronic equipment, thermistors are required. Testing the electrical performance (resistance, insulation and temperature response accuracy) of the thermistor is an indispensable and important link in the production, debugging, inspection, testing and maintenance of military electronic components. [0003] In the traditional detection method, the resistance value of the thermistor needs to be tested and recorded manually with a multimeter or a micro-resistance tester. The test needs to be carried out in a relatively stable temperature environment. Use a multimeter or a micro-resistance tester to measure the resistance of the thermistor at the current temperature, and match the two parameters of temperat...
