INTRODUCTION :

Weighing Indicator XK3190-A12E+ adopts fast speed, high precision Σ-Δ A/D conversion Technology, and special anti- vibration software technology widely applied in electronic Bench scale. floor scale, mechanic - electronic conversion scale (hybrid scale), and so on. weighing system equipped with 1 - 4 at 350 ohm load cell

FUNCTION :

♦ There are some model according the function:

       - A12E+ (only weighing)

       - A12E+ - RS ( RS 232 function for connect to PC )

       - A12E+ - TTL ( TTL 2 output function for semi automatic weighing system )

       - A12E+ - SB ( Score board function )

       - A12E+ - PH ( Peak Hold function for testing device )

       - A12E+ - HLG ( Hi Lo Go alarm function for check weighing )

       - A12  - AV ( LCD display) ( Average hold function for animal weighing )

♦ High precison A/D conversion with readability 1/ 30000

♦ Special digital filtering technology to strenghten anti - vibration ability
