Page 4: Safety Precautions
P82R Instruction Manual Safety precautions 1.1 Appropriate use In addition to differential pressure data, the P82R differential pressure transducer also records positive and negative overpressures. Always observe the operating requirements—particularly the permissible supply voltage—indicated on the rating plate and in the "Technical data" section of this manual. -
Page 5: Symbols
P82R Instruction Manual The electronic components of the instrument contain environmentally hazardous materials and materials that can be reused. For this reason the instrument must be recycled in accordance with the environmental guidelines of the jurisdiction in question once it has been taken permanently out of service. -
Page 6: Instrument Description
Start-up Features Although the P82R pressure transducer is highly robust, it is nevertheless a precision instrument and should be handled with care. Avoid mounting the instrument in the direct vicinity of any sources of radiation or heat, such as heaters, as this could result in measurement errors. -

Page 8: Output Signals
P82R Instruction Manual Observe the required supply voltage (see rating plate) and the connection diagram located on the housing cover. The transducer outputs are protected from short circuits. Instruments supplied with direct current are also protected from reverse polarity. Connecting the supply voltage to the outputs will destroy the transducer. -
Page 9: Calibrating The Zero Point
P82R Instruction Manual Please note: The LCD will not display the correct value when repositioning the S1 switch (from root-extracted to linear). Calibrating the zero point Please remember that it takes roughly 30 to 60 minutes for the pressure transducer to warm up after it is switched on. The output signal may not remain stable during this period. -
