GSI301 Batching scales Digital Weighing Indicator
Standard Function:
◆3 inputs, 3 outputs (3 output relays inside) control
◆High precision A/D conversion with readability 1/30000
◆With 5 points nonlinearity amend
◆If change the former indicator, no need to re-calibrate, only to input parameter of former indicator
◆Embodies with automatic grarimetric filling instruments, catchweigher, alarm for max and min limitation and peak value preserving functions
◆Able to set fixed-value, pre-act value, Max-min limitation, and delay time freely based on different applications
◆1-2 materials available for plus/minus scale; external, self-testing, and free max and min modes are available for catchweigher
◆Standard RS-232/422/485 communication interface, baud rate and way of communication is optional
◆Standard scoreboard interface serial sending signal by 20mA current loop (constant current)
◆Precise simulate signal output with mode of 4-20mA/0-20mA/0-5V/0-10V optional, adjustable
◆Accumulative weight and times is able to be stored, check, delete, and with date-protection when power cut off
◆Able to connect with serial printer to print weighing record, accumulative amount or combined information, kg, t, g, lb is an optional print unit
◆Zero tracking, range for zero (automatic and manual) is free to be set
◆Strong anti-jamming and reliability
◆ESD protection performance: touch 6KV, air 8KV.
◆Able to recover from factory setting
