from actual tem-
perature
Temperature unit,
highest and lowest
value for temperature
set incorrectly
–
Match settings of flow meter and reading
system.
–
Check LRV and URV process parame-
ters, see software instruction manual.
Non-adjustable

–
Check whether the
Func sel

set correctly. If a fixed value is selected,
ensure that the
Fix val

.
Incorrect temperature
measurement with
remote type
–
Check temperature measurement circuit
by measuring resistance between TP1/
TP2 and TP1/TP3. Each value must be
between 50 – 200 Ω.
–
Check temperature measurement circuit
TP2/TP3 and make sure that resistance
is < 10 Ω.
–
Connect Pt100 simulator and check
temperature measurement.
Output signal
deviating from
measured quantity
Incorrect parameter
–
Check parameter
LRV
and
URV
of the
corresponding output signal, and correct,
if necessary.
Incorrect measured
quantity
–
Check measured quantity output and, if
necessary, correct; check parameter
