Storing And Cleaning Of The Sensor; Trouble Shooting Guide - bürkert 8045 Bedienungsanleitung

5.1 STORING AND CLEANING OF THE SENSOR

To avoid any measurement error due to electrode soiling a regular cleaning of the elements
in contact with the medium is recommended (the cleaning frequency depends on the appli-
cation). The sensor can be cleaned with water or another cleaning agent compatible with
the PVDF, stainless steel or PEEK. Do not use abrasive products. After cleaning, always
rinse the measuring element. Before setting back into operation:
- check the gaskets and change them if need be, as well as other damaged elements
(see section 6.7)
- calibrate the "flow zero" point (see section 4.5.3).

5.2 TROUBLE SHOOTING GUIDE

The current output is set to 22 mA in case of an electronic failure and at the start-
up of the device all parameters are set to factory setting values (section 4.6). The
reasons for failure can be seen within "Display 'ERRORx' - output current 22mA" in
the trouble shooting guide below.
