DC voltage measurement: touch the red and black probes to the positive and negative terminals of the battery, respectively; the screen automatically displays the DC voltage value 3. Resistance measurement: touch the red and black probes to both ends of the resistor, respectively; the screen automatically displays the resistance value 4. Continuity test: touch the test probes to both ends of the circuit under test; an audible alert sounds if the circuit is continuous, and there is no response if it is open 5. NCV non-contact voltage detection 6. Display with built-in color backlight Package list: 1. Multimeter x 1 2. Test probes x 2 3. User manual x 1
