SK00-9663-EI-003-00 Usage environment When exposed to accumulated gas such as rotary pump oil mist and CVD (Chemical Vapor Deposition) raw material gas, problems such as *CAUTION* disconnection of filaments and changes in pressure characteristics occur. When using in such an environment, install an isolation valve between this unit and the vacuum chamber, and seal the isolation valve so that it is not exposed to these gases as much as possible.

SK00-9663-EI-003-00 Check for pressure indication Immediately after starting use, check the pressure indication, especially the pressure on the atmospheric pressure side and the zero point side. If necessary, adjust the atmospheric pressure and zero *CAUTION* point. Due to the principle of pirani vacuum gauge, the pressure indication is affected by the environmental temperature.
