During initial powering of the XFM transducer, the flow output signal will be indi-
cating a higher than usual output. This is an indication that the XFM transducer
has not yet attained its minimum operating temperature. This condition will auto-
matically cancel within a few minutes and the transducer should eventually indi-
cate zero.
For the XFM transducer with LCD option: If the LCD diagnostic is activated, the
second line of the LCD will display the time remaining until the end of the warm
up period (Minutes:Seconds format) and will alternatively switch to Totalizer read-
ing indication every 2 seconds.

5.2 Swamping Condition
If a flow of more than 10% above the maximum flow rate of the Mass Flow Meter
is taking place, a condition known as "swamping" may occur. Readings of a
"swamped" meter cannot be assumed to be either accurate or linear. Flow must
be restored to below 110% of maximum meter range. Once flow rates are lowered
to within calibrated range, the swamping condition will end. Operation of the meter
above 110% of maximum calibrated flow may increase recovery time.
Note: Allow the Digital Mass Flow Meter to warm-up for a MINIMUM
of 6 minutes.
,
Note: During the first 6 minutes of the initial powering of the XFM
transducer, the status LED will emit CONSTANT AMBER light.
,
Note: After 6 minutes of the initial powering of the XFM transducer,
the status LED will emit a constant GREEN light (normal operation,
ready to measure). For XFM with LCD option, the screen will reflect
flow and totalizer reading. (see Figure b-4).
