DH Instruments PPC4 Manuel utilisateur

PPC4™

Pressure Controller/Calibrator

Operation and Maintenance Manual

Warning

•High pressure liquids and gases are potentially hazardous. Energy stored

in these liquids and gases can be released unexpectedly and with extreme

force. High pressure systems should be assembled and operated only by

personnel who have been instructed in proper safety practices.

•The PPC4 must be properly earthed. Only use a supply outlet that has a

protective earth contact. If there is any doubt as to the effectiveness of the

supply outlet earth, do not connect the PPC4.

•This instrument is not to be operated in any other manner than that

specified by the manufacturer.
