ference is higher than the plausibility threshold
TSP
, the transmitted da-
ta will be „0“ and the average value will remain unchanged.
Plausibility (
TSP_
) Threshold for plausiblity check: lower limit
which is acceptable for a valid measure-
ment.
Plausibility (
TSP~
) Threshold for plausiblity check: upper limit
which is acceptable for a valid measure-
ment.
When sampling is completed, the average temperature value or „0“ will
be output. At the same time, an impulse is generated which can be used
for the digital outputs. Enter
M.TR.1
as the source and set the hold time
to 0.5 s.
A cut-off interval (time lag) begins after the sampling time has ended
This cut-off interval must expire before the next measurement can start
with the cycle starting conditions described above.
Cut-off interval
(
T.DIS
)
The interval between one completed sam-
pling and the start of a new sampling..
If a measuring cycle does not start during the period
T.OUT
, the saved
average will be deleted and reinitialized when the next cycle begins.
Timeout (
T.OUT
): Time cycle for deleting average value (in
minutes)
Activate auto reset for the ATD function to run cyclically. Limit 1 will then
be ignored. Measurement continues when the Limit 2 is exceeded for the
period configured with
T.DEL
.
Auto reset (
A.RST
): Auto reset on/off
If, during the measurement, the temperature reading falls below Limit 2,
the measurement will be dismissed.
