4.1 INTRODUCTION When the instrument is powered, it starts immediately to work according to the parameters values loaded in its memory. The instrument behaviour and its performance are governed by the value of the stored parameters. At the rst start up the instrument will use a “default” parameter set (factory parameter set); this set is a generic one (e.g. a TC J input is programmed). We recommend to modify the parameter settings to suit your application (e.g.: input type, Control strategy, alarms, etc.) To change these parameters you need to enter the “Conguration mode”. 4.2 INSTRUMENT...

4.5 COMPLETE CONFIGURATION PROCEDURE. 4.8 FACTORY RESET - DEFAULT PARAMETERS LOADING PROCEDURE The conguration parameters are collected in various groups. Every group denes all parameters related with a specic function (e.g.: control, alarms, output functions). Sometime, e.g. when you re-congure an instrument previously used for other works or from other people or when you have made too many errors during conguration and you decided to re-congure the instrument, it is possible to restore the factory conguration. button for more than 5 seconds. 1.
