Initial Transmitter Startup Procedures
To zero the meter:
1. Prepare the meter for zeroing:
a. Apply power to the meter. Wait several minutes to allow the meter to warm up:
• For IFT or RFT transmitters, wait for approximately 30 minutes.
• For Series 1000/2000/3000 transmitters, LF-Series transmitters, and MVD Direct
Connect, wait for approximately 20 minutes.
b. Run the process fluid through the sensor until the sensor temperature reaches the normal
process operating temperature.
c. Close the shutoff valve downstream from the sensor.
d. Ensure that the sensor is completely filled with fluid.
e. Ensure that the process flow has completely stopped.
If fluid is flowing through the sensor, the sensor zero calibration may be
inaccurate, resulting in inaccurate process measurement.
To improve the sensor zero calibration and measurement accuracy, ensure that
process flow through the sensor has completely stopped.
