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.
2. Turn on the electrical power at the power supply.
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.

DANGER
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.
The transmitter will automatically perform diagnostic routines. During this period,
the Warming Up alert is active. The diagnostic routines should complete in
approximately 30 seconds.
