The meter is a handheld and battery-powered small tool, which is specially applied to identify resistor, capacitor, diode and Zener/LED. Besides, it is displayed by large LCD and it will be off automatically after 15 minutes if no button is pushed during this period. Features: 5999-count LCD display. Auto range. Over-rang indication display "OL". Zener diode test. LED test, battery power test. SMD test, DIP component with lead. Low battery indication. Auto power off function.
