Item Type:DC Motor Tachometer Product material: ABS Detection range: 30 RPM - 99999 RPM Mode selection: Mode 3: Calculate signal frequency, 00000r/s-99999r/s. Mode 4: Calculate signal speed, 00000rpm-99999rpm Frequency division coefficient: number of signal cycles for motor rotation ① External Hall Sensor:The frequency division coefficient is 1 ②Brushless Fan, Computer Fan, Server Fan: the frequency division coefficient is generally 2, a small amount is 3 ③Brushless Driver, Brushless Motor with Built in Driver: setting according to the driver instructions, common frequency division coefficients are 3, 6, 12 The frequency division coefficient can be determined or estimated in the engine manual Server fans, high-speed brushless motors: the speed is generally below 20,000 RPM at standard voltage Conventional motors or fans: the speed range is about 3000-8000 RPM at standard voltage Filtering and display stability: ① This meter only reflects the signal state, the display fluctuation is mainly related to the test conditions ② The accuracy of the Hall mounting of the brushless motor, motor vibrations and the load status can lead to speed fluctuations. ③ By adjusting the filter coefficient, the average speed value can be displayed and thus easier to observe. The value changes slowly with a filter coefficient of 16 Hall sensor cable length: approx. 1 m / 3.3 feet. 1x; Product description [Accurate Speed Measurement] 5-digit LED display with measuring range from 30 to 99999 RPM, for detailed engine speed testing.
