Page 9: Safety Procedures And Precautions
DO NOT SUBSTITUTE PARTS OR MODIFY INSTRUMENT Do not install substitute parts or perform any unauthorized modification to the instrument. Return the instrument to an MKS Calibration and Service Center for service and repair to ensure that all safety features are maintained. - Page 10 Safety Procedures and Precautions OPERATE AT SAFE INLET PRESSURES This unit should never be operated at pressures higher than the rated maximum pressure (refer to the product specifications for the maximum allowable pressure). INSTALL A SUITABLE BURST DISC When operating from a pressurized gas source, a suitable burst disc should be installed in the vacuum system to prevent system explosion should the system pressure rise.

Page 11: Chapter One: General Information
Chapter One: General Information Introduction The MKS Type 230E Pressure Transmitter is an absolute transmitter of the capacitance manometer type. The electrical output signal is a 4 to 20mA current which is linear with pressure over the full scale range. An absolute pressure at the P port will cause the output current to increase from 4 mA toward the 20 mA full scale value. -
