Auto-Detect Epson/HP/Canon Mainboard Tester: Diode, Triode, PNP NPN MOSFET, Capacitor, Resistor
- SKU:
- AS-TESTER-TC1
Description
Testing tool for printer mainboards: Canon, HP, Epson & any printer on earch. With built-in rechargable Li-on battery! This God-sent multifunction tester can automatically identify elements and automatic detection of pin layout, and automatic switching range. Yes, I know you can do all these with a multimeter but we all have better things to do than figure out what component it is and how to test it. Howe about having a tool that automatically detect the component, test it and let you know if it 's good or not? You don't need to be an electronic expert to work on your mainboard anymore! Watch the video below for how to use it.
