Professional Integrated Circuit IC Tester Transistor Tester Online Maintenance Digital LED Transistor IC Tester

Description You can test 74ch series 74ls series CD4000 series HEF400 series 4500 series operational amplifiers interface class chip optocouplers transistors automatic identification the regulator voltage value recognition Built in data model all kinds of chips more than 1 300 species more than 420 kinds of transistor data models covering most common devices within 24 feet and can greatly reduce the maintenance workload improve maintenance efficiency The repair wizard 9v laminated battery the same as with ordinary multimeter battery power consumption is quite ordinary digital multimeter Press the enter key can boot first boot automatically perform a self test self test the battery voltage is detected and displayed on the screen after the passage of more than two seconds when the battery voltage is below 7v replace the battery in order to ensure measurement accuracy If there is no alarm you can start measuring work Native AD 10 AD the theoretical resolution of 5v voltage is 0 0048v Not suitable for measuring high power thyristor due to the use of battery powered Zener value should be subject to the measured can not only look at the nominal value Boot the default directory is search directory An ordinary optocoupler optocoupler test up to a dozen parameters a simple measurement optocoupler logics relationship has not much practical significance the machine can test the secondary optocoupler saturation voltage for reference And test the 4 feet opto
