Original New 220V Main Board PCB Circuit Board,Panel For Indicator A12E Weighing Monitor XK3190-A12 LCD

Note: If no LED color is specified, then red or green LEDs will be shipped randomly !

weighing indicator 

basic function:

High precision A/D conversion, the readability of 1/30000;

The code calls convenient display, observation and analysis of weight tolerance instead of feeling;

Special software technology, enhance the system's ability to resist vibration;

Zero tracking range, zero (boot / manual range, respectively);

Digital filtering speed, amplitude and the stability of the time can be set;

With the weighing counting function; (a power-off protection unit weight)

A variety of optional backlight mode;

Random charging; undervoltage indication and protection device;

Random allocation of 6V/4AH maintenance free battery

Optional RS-232 communication port, baud rate selectable, optional communication mode;

Large screen 20mA matching the current loop communication port;

Non standard varieties recommended restructuring:

Reorganized with kg/lb conversion function; (foreign trade for the product)

With automatic calculation of average value of reorganized function; (applicable to animal husbandry scale)

Reorganized with 2 custom output function; (suitable for low speed weighing test)
