Instrument Introduction

     CST608 multi-channel cathodic protection monitoring system using high input impedance voltage follower circuit and zero resistance ammeter circuit inside the instrument with high reliability siliconlab industrial control chip, and TI's precision data converters ADS1211, its highest resolution of 24bit / 10Hz, built- order low -pass filter can effectively eliminate high frequency noise into the measurement cell , the instrument also built-in EMI filter , you can prevent surge voltage shock damage to the equipment , security equipment in industrial environments normal use.

     Instrument capable of simultaneously measuring 8 protection potential and 8 protection current signal, and automatically switches based on the current size of the current range , and can ensure that the entire test data in the weak and the strong current area current region all have a good resolution. Device control firmware uses watchdog to improve the reliability of software is running , you can automatically recover after a failure protection program running . Instrument through the PC software settings ( via Isolated RS232 serial control ) .
