Features: 1. The 2000-word automatic range clamp meter with true effective value can accurately test distorted AC voltage and current signals. 2. With temperature and non-contact voltage detection, the use environment is expanded. 3. Optimize the jaws and increase the position of the meter pen, which is convenient for one-handed operation. 4. Optimize the position of the jack, better safety and beauty, and reduce the entry of dust and foreign objects. 5. Added a back buckle for easy carrying 6. AC current measurement (2A/200A) resolution 1mA 7. AC and DC voltage measurement (600V) 8. Resistance, continuity, diode measurement 9. V ~alert dangerous voltage alarm 10. Temperature test 11. Data retention, background light parameter: 1. Display: 2000 words 2. DC current: 2A/ 20A/ 200A/0.01A/0.001A+/-0.1 (2.5% + 5 words) 3. DC voltage: 2V/20V/200V/600V/0.001V/ 0.01V /0.1V /1V (1.0%+ 3 words) 4. AC voltage: 2V/20V/200V/600V/0.001V/ 0.01V /0.1V /1V (1.0% + 3 words) 5. Buzzer: If the resistance of the tested circuit is less than 30 ohms, the buzzer in the meter will sound a continuous alarm. 6.
