English Manual

Key Features:

• Professional-Grade Accuracy:

  • 6000-count True RMS for precise AC/DC voltage/current measurements.
  • Wide measurement ranges:
    • Voltage: DC (60mV–600V, ±0.5%+2), AC (60mV–600V, ±0.8%+3).
    • Current: DC/AC (600μA–10A, ±0.7%+2 to ±1.0%+3).
    • Resistance: 600Ω–60MΩ (±0.8%+2).
    • Capacitance: 9.999nF–99.99mF (±4%+5).
    • Frequency: 10Hz–10MHz (±0.1%+4).
    • Temperature: -40°C to 1000°C (±1.0%+4).

• Advanced Functions:

  • LoZ (Low Impedance) Mode: Eliminates ghost voltage in capacitive circuits.
  • LPF (Low-Pass Filter): Filters high-frequency noise for stable AC measurements.
  • NCV (Non-Contact Voltage): Detects live wires without physical contact.
  • 31-segment analog bar: Visualizes real-time measurement trends.
  • Max/Min/Peak Capture: Records signal fluctuations and peak values.
