A1500

1. INTRODUCTION

A1500 is a universal process indicator which accepts a large variety of input

signals and sensors. A six-digit LED display shows measured value and all

programming parameters. Instrument configuration is achieved from the keyboard,

without any hardware change. Thus, the selection of input type and type of alarms

action, besides other special functions, are accessed and defined from the frontal

keyboard. The user should read this manual thoroughly before using the instrument. It

must be handled with care and should be used accordingly for best results.
