II. Key Features
1Fully automatic distortion level testing function with internal automatic calibration,Automatic Tracking Filter
2measurable distortion ≥0.01%
3．Set up 30kHz，80kHzLow-pass filters reduce the impact of broadband non-harmonic disturbances (such as noise), allowing for more precise measurement of harmonic distortion in the low-frequency signal range.
4Enhanced the voltage range of the input signal for measuring signal distortion.300 mV～300V。
5Features testing for balanced or unbalanced signals.
6．Added frequency counting function, the frequency of the measured signal can be directly determinedLCDLCD screen for precise display.
7．The oscilloscope output monitoring socket has been retained for users to observe the waveform of the measured signal and the overall filter tuning state during small distortion signal measurements.
8Attenuation network filter characteristics up to90dB～100dB。
9．Utilizes a high-precision true RMS detector for demodulation, effectively reducing demodulation errors.
