It can also be customized for ultra-low frequency measurement of 0.01HZ-100HZ3.Automatic range switching from 00.000Hz (R/M0 to 000 00KHz (KR/ID4.The working mode can be switched by pressing the on, including two working modes: frequency and speed. The working mode is saved after power failure5.The frequency division value can be set with ons, ranging from 1 to 9999 and 0.0001 to 9 9999 gear, frequency division value saved after power failure6. Beautiful appearance, excellent craftsmanship, and convenient useThe 5166FR series frequency/tachometer uses a high-performance microcontroller from Microchip Corporation in the United States as the central processing unit, which has the characteristics of high reliability, strong anti-interference ability, wide measurement range, and high measurement accuracy. This system breaks through the traditional cycle measurement and pulse counting measurement methods in frequency measurement, integrates the advantages of these two measurement methods, and adopts advanced fully synchronous cycle measurement method, enabling the instrument to achieve a qualitative leap in measurement range and accuracy. Therefore, this series of instruments can be widely used in various industries that require high-precision frequency measurement.

Matters needing attention1.It should be used in the normal operating environment of this instrument.2.Choose the correct working mode according to the actual usage requirements.3.Set the frequency division value correctly.4.The input signal should meet the requirements of impedance matching, and impedance transformation should be performed on signals with high internal resistance.5.When inputting high-voltage signals, pay attention to operational safety and do not use signals for instrument setting operations.6.Do not directly touch the crystal oscillator and chip with your hands, as static electricity from the human body can damage the device and reduce performance.
