(16) Burst Mode
The transmitter continuously sends the data stored in it
when the burst mode is set on. Either one of measured
pressure variable, % output value, or 4 to 20 mA
output value can be selected and sent. The data is sent
intermittently as a digital signal at 75 ms intervals
when the transmitter is set in the burst mode. There-
fore, communication by the HART simultaneous
communicator is also possible.
Setting of Burst Mode
F0234.EPS
Call up the Burst option, and set
the data to be sent.
• Pressure variable (PV)
• % output value (% range/current)
• 4 to 20 mA output value (Process
vars/crnt)
