and standard. The FB1100 normally runs in low power mode for standard metering applications.
When running in low power mode, the radio power control function is used to switch to standard power mode and enable the
serial ports. During communication periods, the unit uses the standard power mode and then automatically reverts to low power
mode when the communication period is over.
The local display and FBxWifi can be configured to switch off after a period of inactivity (configurable between 1 and 60 minutes)
or be permanently left on.
When running in low power mode, if you need to use more than the default number of data points for logging, consult the
Emerson FB1100 Flow Computer Instruction Manual (D301752X012) to determine the possible impact on power consumption.
