Digital IC Tester

Description:
The multi-function integrated circuit tester is a professional instrument designed for the first-line microelectronic engineering staff , maintenance staff . Different test mode can be selected 5v mode , 3.3v mode , AUTO mode can test 74HC series 74LS series , CD4000 series , HEF400 Series , 4500 Series , operational amplifiers, interface class chip , optocoupler transistor automatic identification regulator regulator value recognition , and so on . Built-in 13 kinds of various types of chip data model , the transistor data model more than 420 kinds , covering a majority of 24 feet or less common universal device , can significantly reduce the workload and improve work efficiency

The panel has 5 buttons are on the left, right, bottom, and Enter keys.
The next key is used to adjust the directory and change the model number, the or so key to move around the cursor options to change.The Enter key for the switch machine and execute the test command.Gently open the battery cover, add a 2X1.5V laminated battery, and then close the battery cover.Press Enter for more than 2 seconds can boot, boot automatically display the current battery voltage, when the voltage is lower than 2.5V, please replace the battery, the low voltage will affect the reliability of the test result and protection automatic shutdown.
Boot: Enter key press 2 seconds then boot.
Shutdown: 1 in the OFF directory, press Enter button to immediately shutdown.
2 in any directory, press Enter button for more than 10 seconds then off.
3 in no operation after 60 seconds, automatic shutdown
ethods of devices placed:
1, the top of the chip alignment
2, put the most left transistor three slot
3, a 13 foot alignment IC Optocoupler
4, voltage regulator tubes placed IC block 13 and 14 feet.
