Handheld frequency meter gy561 power meter walkie talkie power frequency measuring instruments frequency line

Product Description: Name: GY561 power frequency devices Almost sequence: GY561 frequency power meter using dot matrix LCD display, mainly used to measure radio transmitting equipment (such as handheld radios, vehicle-mounted walkie-talkie) output power and frequency. Due to the built-in load, making the table is more convenient to use, reliability is greatly improved. In only need to measure the frequency of the occasion, an external antenna can be non-contact measurement. Features: Display: LCM display, frequency resolution 0.00MHz (1MHz) Power resolution 0.1 MHz. Range: Power Measurement automatic conversion range, the measured signal exceeds 500 MHz power display “00.0W” measurement model is less than 1 MHz, the frequency display will no longer be accurate. Calibration adjustment: Open the cover, showing the two built-in regulator is located at the bottom left of the frequency of calibration capacitor in instrumental reference, it can be calibrated in the bottom of the power measurement baseline adjustment, the factory has a good tune (5.000V).. Please do not adjust easily. Frequency measurement: 1 MHz — 2400 MHz Power Measurement: 0.1W — 50W Input impedance: 50 Accuracy: 140-170 / 400-470 is better than 10% Sampling time: about 0.2 seconds Operating temperature: 0-40 degrees Battery: three 1.5V AAA alkaline batteries Current consumption: about 100MA Auto power off: about 80 seconds Accessories: adapter, antenna, manual Option: adapter cable (a gift) Warranty: This product warranty for one year from the date of purchase (man-made, water, disassemble the exception)
