11.1 Recommendations for Transmitter Calibration

SMV800 requires Pressure Calibration and Temperature Calibration.
SMV800 SmartLine Multivariable Transmitter does require calibration after years in operation to
maintain accuracy performance. Calibration of a process-connected Transmitter does not always
generate the best result due to process noise and stability. It is recommended to conduct calibration in
a laboratory environment using certified precision equipment.

11.2 Calibration Procedures

Calibrations should be carried out in analog mode using equipment with traceable certificates and
handheld communicator or local display.
Calibration information and procedures for a transmitter operating in the HART/DE mode and
Modbus are provided in the relevant protocol manuals, see References.

11.2.1 Dual/Triple Cal

SMV800 HART models are optionally offered with multiple calibrations for pressure. In lieu of a
standard factory calibration, units can be supplied with 1, 2, or 3 customer specified
calibrations. These calibrations are stored in the meter body and provide users with factory calibrated
performance at up to three different calibrated ranges for Differential Pressure and Gauge or Absolute
Pressure. This increases application flexibility without requiring any costly recalibration or additional
inventory.
