10.7Resetting All Configuration and Calibration Values to Factory Settings

Introduction

A “cold reset” function is available to return ALL configuration values to the factory settings shown in Table 5-1. During a cold reset the cal factor will be changed to match the cell constant. The calibration trim or TDS conversion factor will be removed. All alarms will be cleared and outputs will go to zero. Some I/O setup values will also be returned to the factory defaults.

This “cold reset” contrasts with the “warm reset” that occurs following loss of power and at the end of system setup (see Section 5). During a warm reset, alarms are not cleared, and outputs are maintained at their last value prior to the loss of power or initiation of the cold reset. A warm reset has no effect on configuration or calibration values.

Procedure

To do a cold reset, returning all configuration and calibration values to their factory settings, follow the procedure in Table 10-6.
