XJP-10B Speed digital display instrumentDetailed product description：

I. Overview
XJP-10B speed digital display instrument is a new generation intelligent speed digital display instrument that uses a new single-chip microprocessor as the main chip. It includes most of the functions of speed digital display instruments, with six digit data display and one digit function display, capable of measuring cycle, frequency, and speed, and has counting function; And it has expansion functions: upper and lower limit relay alarm, 4-20mA DC current output, can be equipped with a micro printer or dynamic recording software.

There are seven digital tubes on the panel, with the leftmost tube displaying function codes from 0 to 3, representing the respective functions, which are operated and converted by the "◄" film button; A set of six digit digital displays on the right end are used for functional display, and the corresponding parameters are displayed during setup.
Key function:
1. "SET" key: Enter the parameter setting state and save to exit.
2. "▲" key: When setting the state, the flashing position is increased by 1; When in counting mode, hold down this key to stop counting, and release it to start counting again from zero.
3. "◄" key: Shift key when setting the state; When not in the set state, this key is a function conversion key, and every time it is pressed, the green code is displayed in a loop from 0 to 3.
4. "RST" key: Reset key.
