Parameter Function
Sampling time
(
T.ACT
)
During the sampling time the temperature is
detected and stored as a temperature val-
ue.

Display and output of temperature reading
[
ANO
]
The parameter
ANO
(normal display mode) defines which temperature
value is saved during sampling.
Parameter Function
Display mode (
ANO
)
„
T
=0“ displays the lower temperature range
limit during the measurement.
„
T.HLD
“ indicates the previous tempera-
ture reading during the current measure-
ment.
The green status LED indicates that a measurement is currently in pro-
cess.
Average weighting [
F-PR
] Plausibility check
When the sampling time has ended, an average value is calculated for
recorded measuring cycles. The temperature reading is weighted with
the previously saved average value and added.
Parameter Function
Weighted average
(
F-PR
)
Factor for average weighting. If you enter
100%, averaging will be off.
The smaller you set the
F-PR
factor, the stronger the weighting will be.
When the averaging function is activated (
F-PR
<100%) a plausibility
check will be performed. The difference in temperature between the cur-
rent reading and the previously stored average is determined. If this de-
viation is greater than the plausibility threshold
TSP
, the transmitted da-
ta will be „0“ and the average value will remain unchanged.
Enter the upper threshold and lower threshold for the permissible devia-
tion separately.
The parameter
T.ACT
= 0 automatically recognizes the
end of the discontinuous process (measured temperature
< L2). The pyrometer then shows "Auto" instead of the time
under parameter
T.ACT
.
