IC Controls - Model 455 - Conductivity Microprocessor Analyzer - User Manual

The model 455 is IC Controls1 industrial-quality remote operational CONDUCTIVITY analyzer, designed to give maximum flexibility, reliability, and ease-of-use. The model 455 is shipped from the factory calibrated at 0 nS/cm to 1 000 fiS/cm and 4 inA to 20 niA and should not require recalibration other than sensor cell constant installation (if different from 1.0/cm). It has four auto-ranging input ranges, two isolated 4 mA to 20 mA outputs, two 10 A SPDT relays, plus a serial communication port. Its microprocessor intelligence recognizes specific conductivity standards to auto-calibrate, holds output during calibration, notifies user of diagnosed sensor or analyzer faults, plus stores in memory the last 12 calibration records, 1 000 minute measurement trend, alarms, power outages, and diagnostic messages, all date and time stamped.
