Page 4: Product Description
2 | Product Description Product Description The mobile gauge TPP 900 consists of combined Piezoresistive and Pirani sensors whose measurement principles are based respectively on the change of resistance of a strain gauge resulting from the diaphragm deflection and the thermal conductivity of gases. The Piezoresistive sensor provides direct measurements which are independent on the gas nature while the Pirani sensor uses an indirect measurement method, dependent on the gas nature, see Adjust Gas Correction Factor [► 15]. -
Page 5: Proper Use
Transport and Storage | 3 2.4 Proper Use The TPP 900 serves exclusively to measure total pressure in a range of: – 1200 … 5 x 10 mbar. 2.5 Improper Use The use for purposes not mentioned above is regarded as improper, especially: –... -

Page 12: Adjustment
5 | Operation 5.4 Adjustment The gauge is factory calibrated in upright position. Other orientations, different climatic conditions, extreme temperature changes, ageing or contamination may necessitate re- adjustment. NOTE Conduct adjustment at the same ambient temperature at which the device is typically operated. - Page 13 Operation | 5 Adjustment to Zero Pressure NOTE For adjustment on zero pressure the current pressure inside the sensor has to be less than 1 x 10 mbar. The pressure reading must be less than 4 x 10 mbar, otherwise adjustment is denied and the error message "Err"...
