process. 

 

4.3 

Maintenance 

Soiling of the sensor head results in falsification of the measured 
value. Therefore, the sensor head must be checked regularly for 
soiling. In the case of heavy soiling or when the sensor head is 
wetted with liquids, the sensor outputs an error signal. In this case, 
clean the sensor as described below. If the error signal does not 
disappear after cleaning and drying, the sensor must be sent to the 
manufacturer for examination.

General Concluding Remarks 

The  conclusions  to  be  drawn  from  the  measurement  results  are 
related  to  the  individual  conditions  and  the  knowledge  from 
professional experience for each user.  

Warranty Conditions

 

Gann  Mess-  u.  Regeltechnik  GmbH  shall  rectify  material  or 
manufacturing  defects  at  no  cost  by  repair  or  replacement  of  the 
defective  part  at  its  discretion  that  occur  within  six  months  of 
purchase  or  one  year  of  despatch  from  the  factory,  whichever 
period  ends  first.  Neither  the  replacement  nor  the  repair  of  a  part 
constitutes a new warranty or an extension of the original warranty 
period. 

Batteries  or  other  wear  parts  such  as  cables  or  filter  fabric  are 
excluded from the warranty.
