Logger

1. INTRODUCTION

The Field Logger is versatile data acquisition equipment for process variables,

capable of on-line or stand alone operation. When loaded with a Real Time Clock and

non-volatile memory, it can register up to 128k readings. Its universal input channels

accept a large variety of sensors and standard signals as listed in table Field Logger

Input Signals, below.

A Configuration program (Windows 95, 98 or NT) is provided for an easy

configuration of all the internal parameters.
