Menu 3: Diagnostic Data
T1/T2 (raw):
Signal run times along complete signal
path including pipe wall and transducer enclosure.
dt (raw):
Measured time difference of T1/T2 (raw).
XDCR (DCR=Transducer):
Signal run time within
transducer.
Pipe delay:
Signal run time within pipe wall.
qp:
Compensation factor considering changes in
temperature (and therefore changes in speed of sound
of fluid).
Coating delay:
Delay in signal run time generated by
coating (if applicable).
Lambda Corr.:
Delay can be manually edited (not
recommended, only for maintenance) by multiples of
wave length of signal.
Delay Corr:
Shows Lambda Corr in seconds.
SOFTWARE UPDATE
Check software version
Before making any software update, check version of
software.
Switch off transmitter and restart it. During “start” locate
the version at the bottom of start screen (see arrow).
Note this value.
Consult GPI/website for latest revision levels. If you are
using an earlier version, contact GPI for updates and
