Chapter Six:  Maintenance and Troubleshooting 

General Maintenance 

For best accuracy and repeatability, MKS recommends that you: 

  Zero the unit regularly 

 

Follow the procedure described in How To Zero the Type 631D Transducer

,

 page 37, on 

a regular basis. 

  Schedule re-calibration annually 

 

Follow an annual recalibration schedule, if no other time interval has been specifically 
established.  

  Periodically check for wear on the cables and inspect the enclosure for visible signs of 

damage
