GY561 Digital Frequency Counter & Power Meter


GY561 frequency power dot matrix liquid crystal display used in the table, mainly for the measurement of radio transmitting equipment (such as handheld radios, vehicle-mounted radio) output power, and frequency. As the built-in load, making the table more convenient to use, greatly improving reliability. Only need to measure the frequency of the occasion, an external antenna can be non-contact measurement.


Show: LCM display, frequency resolution 0. 00MHz (1MHz). Power resolution 0.1 MHz
Range: automatic conversion of power measurement range, the measured signals above 500 MHz Power Display "00.0W" measurement model is lower than 1 MHz, the frequency display will no longer be accurate.
Calibration adjustment: open the cover, showing two built-in regulator located in the lower left is the frequency of calibration capacitors, in a reference instrument, you can calibrate the power measurement is below the benchmark adjustment, the factory has been adjusted (5.000V ) do not be easily adjusted.
