Standard maintenance and repair services are available at all of our regional MKS Calibration
and Service Centers listed on the back cover. In addition, MKS accepts the instruments of other
manufacturers for recalibration using the Primary and Transfer Standard calibration equipment
located at all of our regional service centers. Should any difficulties arise in the use of your Type
670 instrument, or to obtain information about companion products MKS offers, contact any
authorized MKS Calibration and Service Center. If it is necessary to return the instrument to
MKS, please obtain an ERA Number (Equipment Return Authorization Number) from the MKS
Calibration and Service Center before shipping. The ERA Number expedites handling and
ensures proper servicing of your instrument.
Please refer to the inside of the back cover of this manual for a list of MKS Calibration and
Service Centers.
Warning
All returns to MKS Instruments must be free of harmful,
corrosive, radioactive, or toxic materials.
Your 670 instrument can be calibrated with or without the pressure transducer. If you are using
your 670 instrument with a high accuracy pressure transducer, and the units require calibration,
you may wish to return both units to MKS. Calibrating the units together ensures the best
possible accuracy.
