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.
