2 Quick start
Topics covered in this chapter:
• Power up the meter
• Check meter status
• Make a startup connection to the transmitter
• Characterize the flowmeter (if required)
• Verify mass flow measurement
• Verify the zero
2.1 Power up the meter
The meter must be powered up for all configuration and commissioning tasks, or for
process measurement.
1.
Ensure that all device covers and seals are closed.
WARNING!
To prevent ignition of flammable or combustible atmospheres, ensure that all covers
and seals are tightly closed. For hazardous area installations, applying power while
housing covers are removed or loose can cause an explosion.
2. Turn on the electrical power at the power supply.
Postrequisites
Although the sensor is ready to measure shortly after power-up, the electronics can take
up to 10 minutes to reach thermal equilibrium. Therefore, if this is the initial startup, or if
power has been off long enough to allow components to reach ambient temperature,
allow the electronics equalize for approximately 10 minutes.
2.2 Check meter status
Check the meter for any error conditions that require user action or that affect
measurement accuracy.
1.
Wait approximately 10 seconds for the power-up sequence to complete.
Immediately after power-up, the transmitter runs through diagnostic routines and
checks for error conditions.
2. Connect to the transmitter and check for active alerts.
