★ Scanning sine wave with low distortion rate

THD ≤ 0.15%, 20Hz~20 kHz. It is most suitable for detecting abnormal sounds in electroacoustic components such as speakers.

★ Digital display voltmeter and frequency meter

Full digital display of voltage and frequency values, meeting precision measurement requirements, and more durable and impact resistant than traditional pointer meters

★ Logarithmic sweep frequency

It can manually or automatically perform logarithmic frequency scanning, and the frequency range for starting/stopping scanning can be set as needed.

★ Easy to learn and use

The button functions are simple and clear, and non professionals can also use them, providing 20W, 60W, 100W, and 200W options

Models with different output powers are available for purchase, and all come with triple short-circuit protection with a voltage resolution of 0.001V

The pressure gauge, combined with coarse and fine volume adjustment buttons, can easily adjust the desired voltage. For the receiver and ears

The precise low voltage value required by the machine is particularly easy to set.

★ Excellent reliability

With over 20 years of professional design experience, the failure rate is extremely low, the stability is high, and it is not afraid of continuous use around the clock.
