10KHz-10MHz Line EMI Meter Mains Noise Analyzer EMI Measuring Device w/ OLED Display OLED screen displays noise voltage value and AC voltage value There are small speakers that can directly amplify the noise and output it. The size and frequency of the noise can be roughly judged by the sound to determine its source. Plug directly into the wall socket (power socket), no battery required; The loudspeaker plays the sound of EMI and demodulates the amplitude in order to identify the source of EMI (such as AM or shortwave radio, electric motor and electric arc). Description: The main function of this AC mains noise tester is to display the current voltage and noise voltage of the mains through the panel's OLED dot matrix screen. In this way, everyone can see the current state of the mains power very intuitively, and have an accurate judgment on the quality of the power supply. Features: - OLED screen displays noise voltage and AC voltage - There are small speakers that can directly amplify the noise output, and judge the noise intensity and frequency by sound - Plug directly into a wall socket (power socket) - The speaker plays EMI sounds and amplitudes are demodulated to identify EMI sources (such as AM or shortwave radios, motors and arcs) Specifications: - Input voltage: AC 85Vac - 250Vac 50/60Hz (Accuracy: ±1 VAC) - Frequency Range: 10KHz - 10MHz - Noise Range: 1mV - 1999mV - Measurement Accuracy: ±5% @ 1MHZ; +5% to -50% @ 10 KHz to 10MHz - Noise Indication: 4 digits yellow and blue two-color OLED digital dot matrix display - Dimensions: 132 x 91 x 41mm - Machine weight: 150g Package Included: - 1 x Mains Noise Analyzer - 1 x 0.8m AC Power Cable Reminder: This tester is mainly used to measure the noise voltage value of the high frequency 10KHz-10MHz frequency band, and some power filters have no obvious noise filtering effect in this frequency band, and may even slightly increase the effect of the noise voltage value in this frequency band. . Therefore, the value measured by the tester is only for the customer as an objective reference, and the customer is requested to comprehensively judge the effect of the filter
