Dual-Parameter Real-Time Display

  • OLED dot-matrix screen clearly shows AC voltage (e.g., 126.1 mV) and noise voltage (e.g., 221 μV), enabling dynamic comparison before and after power conditioning.
  • Noise Progress Bar: Length adjusts in real time with noise intensity—longer bars indicate stronger interference for quick assessment.

High-Frequency Noise Detection

  • Specifically designed to measure 10KHz–10MHz high-frequency noise, covering common interference sources (e.g., AM/shortwave radio signals, motors, arcing).
  • Note: Some filters may have limited suppression effects on this frequency range; test data should be evaluated comprehensively.

Acoustic Diagnostics

  • Built-in speaker amplifies and outputs noise signals, helping users identify interference sources (e.g., radio signals or EMI from devices) via amplitude and frequency.

Convenient Power Supply

  • Directly plugs into 220V/50Hz AC outlets—no batteries required. Includes a detachable 0.8m two-core power cord.
  • Input Voltage: 85V–250V AC (50/60Hz, ±5%–10% tolerance)
  • Measurement Range: 1mV–1999mV noise voltage
  • Accuracy: ±5%@1MHz; ±5% to −50%@10KHz–10MHz
  • Display: 4-digit yellow/blue dual-color OLED screen
  • Dimensions/Weight: 132×91×41mm / 150g

Operation Guide

Plug the test lead (AC power cord) into the power source. The meter will display noise in millivolts AC. Let the meter remain plugged in for at least 30 seconds​to stabilize the readings.

General guidelines:

<50mV: Excellent

<100mV: Very good

<800mV: Good

<1000mV: Average

<1500mV: Poor

Operation conditions:

  • Indoor use only
  • Operating temperature 28∘C±10∘C
  • Humidity 0 to 90% non-condensing
  • Altitude up to 2,000 meters
