External absolute pressure modules can be added to the C75, C100, or C150 series of portable multifunction calibrators to add pressure measurement capability to your unit. Not compatible with C50 or T150.
Pressure simulation with these modules also requires a user supplied pressure pump.
Pressure modules are digital and connected through a RS485 cable to the digital input corrector. All data is digital. Measurements are compensated in temperature due to a polynomial correction implemented into the EEPROM at the factory.
