3 Quick start
3.1 Power up the transmitter
The transmitter must be powered up for all configuration and commissioning tasks, or for process
measurement.
Procedure
1. Ensure that all transmitter and sensor 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.
The transmitter will automatically perform diagnostic routines. During this period, Alert 009 is active.
The diagnostic routines should complete in approximately 30 seconds.
Postrequisites
Although the sensor is ready to receive process fluid 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 to warm up for
approximately 10 minutes before relying on process measurements. During this warm-up period, you may
observe minor measurement instability or inaccuracy.
3.2 Check meter status
Check the meter for any error conditions that require user action or that affect measurement accuracy.
Procedure
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. During the power-up sequence, Alert A009 is active. This alert should clear automatically
when the power-up sequence is complete.
2. Check the status LED on the transmitter.

Description
Recommendation
Green
No alerts are active.
Continue with configuration or process
measurement.
Yellow
One or more low-severity alerts are active.
A low-severity alert condition does not affect
measurement accuracy or output behavior.
You can continue with configuration or
process measurement. If you choose, you can
identify and resolve the alert condition.
