Average temperature configuration

The 644 transmitter ordered and configured for dual-sensors can output and display the
Average temperature of any two inputs. Use the following procedures to configure the
transmitter to measure the Average temperature:
Note
This procedure assumes the Average Temperature is a calculated output of the device but does
not re-assign it as the Primary Variable. If it is desired for Average to be the transmitter's primary
variable see
Average temperature configuration with a Field Communicator
From the HOME screen, enter the Fast Key sequence.
