Instruction Manual Wiring Rosemount 396RVP LIQ-MAN-396R-396RVP March 2017 Section 5: Startup and Calibration Sartup To obtain best accuracy, the sensor must be calibrated as a loop with the transmitter. Please refer to the respective transmitter instruction manual for proper calibration procedures.
Startup and Calibration Instruction Manual March 2017 LIQ-MAN-396R-396RVP 5.2.2 Recommended pH Sensor Standardization For maximum accuracy, the sensor can be standardized on-line or with a process grab sample after a buffer calibration has been performed and the sensor has been conditioned to the process.
Section 6: Maintenance Maintenance Rosemount 396R and 396RVP sensors are disposable type sensors and require minimum maintenance. These sensors should be removed from the process periodically and checked in buffer solutions. If the sensor will not calibrate, refer to your transmitter instruction manual for proper test procedures.
Maintenance Instruction Manual March 2017 LIQ-MAN-396R-396RVP WARNING Before removing the sensor from the ball valve, be absolutely certain that the ball valve is fully closed. Leakage from the male connector threads may indicate that the male connector is still under pressure.
