MAINTENANCE

Calibration is the only routine operation that is necessary on a regular basis.

The Z230 is a very stable analyser with a drift rate of better than 2% of reading per month.  
How often the calibration is checked or verified depends on the quality regime being operated 
at the installation site. Typically monthly checks are found to be adequate. 

WARNING

Opening the analyser case will expose you to mains voltage. Disconnect the 

analyser from the mains supply and any potentially hazardous process wiring 

before opening the case.

6.1  Ordering parts

Should a failure occur, return the instrument to your local MTL Gas sales office for repair.  
When ordering spares or raising queries on the instrument, it is important to quote its serial 
number or job number.  These numbers are on the data label located on the rear panel of the 
instrument. 

Our contact details can be found on the back page of this manual.
