[Example 1: Measured temperature value when the temperature input value is changed
from 250.0
to 260.0 ]
When the time constant setting is 3200ms (3.2s), the measured temperature value
changes as indicated below.
At 3200ms (3.2s) after the temperature input value is changed to 260.0 , the
measured temperature value reaches 63.2% (256.3 )of the value when sampling
processing is selected.
Figure 3.4 Measured temperature value when the temperature input value is changed from 250.0 to 260.0
[Example2: Measured temperature value when the change of temperature input value is a
waveform with ringing]
The changes of measured temperature values when the time constant setting is
1280ms(1.28s), 640ms(0.64s) or the moving average processing is 4 times are shown
below.
