3-3 Operation of the Models MT 3809 and MT 3819 Flowmeters with a Smart Meter Manager Transmitter
with or without Optional Alarms and Pulse Output for totalization
a. Start-up the meter as described in Section 3-2.
b. Programming performed prior to shipment (parameters)
The SMM transmitter with or without alarms and pulse output is
preprogrammed prior to shipment for the following parameters based
on the order information, meter configuration and application.
If parameters are not specified in the customer purchase order, the
defaults inherent to the electronics will be as shown in (parenthesis).
