Rosemount 8712
3-12
Calibration Number The sensor calibration number is a 16-digit number used to identify sensors
calibrated at the Rosemount factory. The calibration number is also printed
inside the sensor terminal block or on the sensor name plate. The number
provides detailed calibration information to the Rosemount 8712. To function
properly within accuracy specifications, the number stored in the transmitter
must match the calibration number on the sensor exactly.
NOTE
Sensors from manufacturers other than Rosemount Inc. can also be
calibrated at the Rosemount factory. Check the sensor for Rosemount
calibration tags to determine if a 16-digit calibration number exists for your
sensor.
NOTE
Be sure the calibration number reflects a calibration to a Rosemount
reference transmitter. If the calibration number was generated by a means
other than a certified Rosemount flow lab, accuracy of the system may be
compromised.
If your sensor is not a Rosemount sensor and was not calibrated at the
Rosemount factory, contact your Rosemount representative for assistance.
If your sensor is imprinted with an eight-digit number or a k-factor, check in
the sensor wiring compartment for the sixteen-digit calibration number. If
there is no serial number, contact the factory for a proper conversion.
PV Damping Adjustable between 0.0 and 256 seconds
PV Damping allows selection of a response time, in seconds, to a step
change in flow rate. It is most often used to smooth fluctuations in output.
