Professional Integrated Circuit Online Maintenance Digital LED Transistor IC Chips Tester IC Tester (A)

TSH series multifunctional integrated circuit tester is a professional instrument designed for first-line microelectronic engineering personnel.
Different test modes such as 5v mode, 3.3v mode and AUTO mode can be selected to test i74H series, 748 series, CD4000 series, HEF400 series, 4500 series, operational amplifier, interface chip, optocoupler, automatic identification of most body tube, identification of voltage regulator tube, etc.
There are more than 1300 kinds of chip data models and 420 kinds of transistor data transverse types, covering most common common devices within 24 feet, which can greatly reduce workload and improve work efficiency.
There are seven keys on the panel: up, down, left, right and Enter, and the shortcut keys 0 and P. The up and down keys are used to adjust the directory and change the model number, and the left and right keys are used to move the cursor left and right to select the item to be changed.
The Enter key is used to switch on and off machines and execute test commands. Open the back cover of the battery, put in 2 no.5 1.5v batteries, and then close the battery cover. Press Enter for more than 2 seconds before starting the machine. When starting the machine, the current battery voltage will be displayed automatically. If the battery is too low, please replace the battery.
