  • Page 9: Introduction

    Introduction Stratos Evo is a 4-wire analyzer for process analysis applications. The analyzer comes as basic device for measurement with digital sensors ( Memosens, optical oxygen measurement, inductive conductivity measurement). All measuring functions are stored in an internal memory. You select a measuring function to configure the analyzer for a specific measuring task.
  • Page 10 The device provides two parameter sets which can be switched manually or via a control input for different process adaptations or different process conditions. For an overview of parameter sets (original for copy), refer to the CD or www.knick.de. Password protection Password protection (passcode) for granting access rights during operation can be configured.

  • Page 122: Calibration

    Calibration Note: • All calibration procedures must be performed by trained personnel. Incorrectly set parameters may go unnoticed, but change the measuring properties. • The response time of the sensor and temperature probe is considerably reduced when the sensor is first moved about in the buffer solution and then held still. The device can only operate properly when the buffer solutions used correspond to the configured set.
