Introduction: The QWA-3B clock tester is suitable for precise measurement of 32.768KHz crystal oscillator clock circuits such as computer motherboards and electronic calendars. It has three ranges: ppm (one millionth difference), s/d (daily error), and s/m (monthly error). The QWA-3B clock tester adopts a non-contact method without the need for electrical connection to the tested circuit. It is equipped with a luxurious aluminum alloy shell and a super large sensor area, making reception more sensitive. It has a built-in fast processor and TCXO accuracy of better than 0.5ppm. The strength of the tested signal is indicated by a 16 level level display, which is intuitive and clear to use. It can set upper and lower limit values, and automatically alarms if it exceeds the range. We solemnly promise that the performance of our QWA-3B motherboard clock tester, including sensitivity and anti-interference performance, is stronger than similar products from other companies on the market, and it has more functions. Technical features: 1. Aluminum alloy shell 2. Measurable frequency 32.768KHz 3. Attached crystal PPm value testing port 4. The display mode adopts a 4-digit LED digital tube 5. Three ranges: PPm, s/d, s/m 6. Configure one 1.0 meter high sensitivity probe to accommodate testing on larger circuit boards 7. High precision temperature compensation clock reference, adapted to seasonal temperature changes, with an accuracy better than 0.4ppm 8. Volume: 260 x 120 x 220mm
