Feature:
1. Digital Tachometer: The measurement range is 0 to 9999, the measurement accuracy is + (2percent +1), the display refresh rate is 2 times second.
2. LED Display Screen: This digital tachometer is equipped with 4 digit LED display screen, providing clear readings, making it easy to read even in low light conditions. It displays LLLL for low speeds and HHHH for high speeds.
3. Easy Parameter Setting: Press and hold the SET button for 3 seconds to enter parameter settings, press the SET key continuously to set different parameters, which will automatically store and close after setting.
4. Sound Prompt: You can set upper and lower limit values, and when the speed exceeds the limit, the tachometer will sound to prompt and indicate the over speed condition.
5. Wide Application: This digital RPM speed meter is suitable for various industrial machines such as lathes, conveyors, and quality testing equipment.

Functional Parameters:
H1: Upper limit value, default 9000
The maximum upper limit value is 9999. When set to 0000, this function is turned off
When the speed exceeds the maximum value, it displays HHHH and rings to output
The upper limit value only judges the data value and does not need to consider the decimal point
H2: Lower limit value, default 0000
The maximum lower limit value is 9999, when set to 0000, there will also be a ringing output after stopping
The lower limit value only determines the data value and does not need to consider the decimal point
H3: Speed mode, default 4
1: 000.0 RPS 999.9 RPS
2: 00.00 RPS 99.99 RPS
3: 0000 RPS 9999 RPS
4: 0000 RPM 9999 RPM
5: 00.00 RPM 99.99 RPM (ultra low speed function)
H4: Speed ratio, default 1
Data range 0.001 9.999
The magnification can be set according to the rotational speed
For example, the ratio of the reducer on the motor
For example, if the motor exceeds the 9999 range, the data can be reduced to 0.1X by setting this parameter to 0.100, so that this meter can measure signals up to tens of thousands of RPM
H5: Ringing delay, default 1
When the upper and lower limit conditions are reached, the meter will detect and judge whether the ring output is ringing multiple times within a certain time
This parameter determines the unit of time length in seconds, with a maximum of 999.9 seconds
H6: Ringing duration, default 999.9
When the bell rings, this parameter can be set to automatically stop ringing after a certain period of time
When set to 999.9, it rings continuously
When set to 000.0, it does not ring
H7: Ring stop mode, default 1
1. Stop conditions: End of duration, restoration of speed, press the + key
2. Stop conditions: End of duration, press the + key
H8: Sensitivity, default 1
The data range is 1 5. When the parameter is 5, the response is slow and the data jitter is small
H9: Ringing and indicator light, default 1
When the speed reaches the limit, make a sound
When the speed reaches the limit, no sound is emitted, but the indicator light is on

Package List:
1 x Digital LED Tachometer
Note:
1. Try to minimize the use of strong electromagnetic devices to avoid interference; 2. Ensure that the hall switch and magnet are securely fixed during the testing process to prevent vibration from causing fluctuations or inaccurate readings. Additionally, the distance between the hall switch and magnet should not exceed 10mm.
