It is most suitable for detecting abnormal sounds of electroacoustic components such as speakers.
Digital display voltmeter and frequency meter
Full digital display of voltage value and frequency value, which meets the requirements of precision measurement, and is more durable than traditional analog meters, and is resistant to shock logarithmic sweep
It can be manually or automatically logarithmic sweep, the start/stop sweep frequency range can be set arbitrarily according to needs.
Easy to learn and use
The button function is simple and clear, and it will also be used by non-professionals. It provides models with different output powers such as 20W, 60W, 100W and 200W, and is equipped with triple short-circuit protection circuits, which can tolerate long-term output short-circuits. Will not damage the instrument.
The voltage value has coarse adjustment and fine adjustment setting buttons
A voltmeter with a resolution of 0.001V, supplemented by coarse and fine volume adjustment buttons, can easily adjust the required voltage. It is especially easy to set the precise low voltage value required by the receiver and earphone.
Excellent reliability
With more than 20 years of experience in professional design, the failure rate is extremely low, the stability is high, and it is not afraid of continuous use all-weather.
The Fo value can be tested manually, and the frequency can also be fine-tuned
The digital display frequency meter, supplemented by the frequency fine-tuning button, can accurately measure the Fo value of the lowest resonance frequency of speakers, etc.
Basic specifications:
Frequency range: 20Hz~20kHz in one range
Frequency response: ≦±0.25dB, 20Hz~20 kHz.
Sweep mode: manual or automatic sweep in a range. Any frequency sweep can be set
Signal: Sine wave, THD≦0.15%, (0.1% Typical.) (20Hz~20 kHz.)
