TA806A Multimeter Digital Voltage Meter Automatic Resistance Tester 4000 count Product features: 1. Fully automatic identification and measurement: After starting the machine, it can measure AC/DC voltage, resistance, on/off, and automatically identify gear changes 2. AC voltage measurement: The red/black probe contacts the zero/live wire respectively, and the screen automatically displays the AC voltage value 3. DC voltage measurement: The red/black probe contacts the positive and negative poles of the battery respectively, and the screen automatically displays the DC voltage value. 4. Resistance measurement: The red/black probes touch both ends of the resistance, and the screen automatically displays the resistance value. 5. On/off test: When the probe contacts both ends of the tested route, the channel will emit an alarm sound, and if there is an open circuit, there will be no response.
