Large Screen Digital Fully Automatic Smart Multimeter 1. DC voltage: 0.01 mV - 1000 V +-0.5% of reading +5 digits 2. AC voltage: 0.01 mV - 750 V +-0.8% of reading +5 digits 3. DCAC current: 1 μA - 100 A +-1% of reading +5 digits 4. Resistance: 0.1ohm - 100 Mohm +-0.8% of reading +5 digits 5. Capacitance: 0.01 nF - 100 μF +-4% of reading +5 digits 6. Frequency: 1 Hz - 10 MHz +-1% of reading +5 digits 7. Duty cycle: 10% - 95% +-1.0% of reading +15 digits 8. Temperature range: -20 to 1000 °C (0-1832 °F); this range applies only to the meter; actual measurement depends on the probe 9. Maximum count: 4-digit display, maximum value 9999 10. Display: VA color screen 11. Functions: analog bar graph, auto-range, neutralhot wire measurement, NCV detection, diode test, continuity buzzer, maxminaverage, relative value, data hold, true RMS, fuse blown alert, low battery indicator, flashlight 12. Auto-off: 10 minutes (can be manually disabled) 13. Power supply: - TA805A: 4 x 1.5V AAA batteries (not included) - TA805B: built-in 3.7V1000mAh lithium battery, supports 5W Qi wireless charging 14. Type K thermocouple: probe measurement range -20 to 200°C (accuracy +-2.5%) 15. Display size: about 73 x 51mm 16. Size: about 15.3 x 7.1 x 2.7cm 17. Weight: about 240g Features: 1. After power-on, measures ACDC voltage, resistance, and continuity; automatically detects and switches ranges 2. VA true-color display with backlight 3. NCV non-contact voltage detection: when the front of the meter is brought near a live circuit, it emits a continuous audible alarm 4. Liveneutral wire identification: touch the live wire and neutral wire separately with the red probe; the live wire will trigger a red indicator light alarm, while the neutral wire will not 5. Temperature measurement: place the temperature probe into the liquid being tested; the display shows both Celsius and Fahrenheit simultaneously 6. Capacitance measurement: touch the red and black probes to the two terminals of the capacitor; read the value once it stabilizes 7. Protective case: made of soft PVC material, effectively protects against dust, shocks, and drops Package list: 1. Multimeter x 1 2. Test leads x 2 3. Thermocouples x 2 4. Carrying case x 1 5.
