Instructions：

This is a multi-functional maintenance tester specially designed for

maintenance personnel, you can choose different test modes, 5v mode, 3.3v

mode, auto mode, etc., you can test 74ch series, 74ls series, CD4000 series,

HEF400 series, 4500 series, operational amplifiers, interface type chips,

optocouplers, transistor automatic identification, voltage regulator tube

voltage value identification, etc. There are more than 1,300 built-in chip data

models and more than 420 transistor data models, covering most of the

common devices within 24 pins

1、 For chip test, please press the direction shown to put the chip on the left

and press the Enter key to test
