Notes: (1)
- in the case of 3-wire sensors, the
Line resistance
parameter must be equal to
0.00 Ω
(automatic compensation)
(2)
- applies to analogue inputs (mA, V, mV, Ω)
(3)
- in the case of
FiLtration
=
1
the response time is equal to 1 s, in the case of
FiLtration
=
10
it is equal to at
least 2.5 s. Higher degree of filtration means a "smoother" measured value and a longer response time, which
is recommended in the case turbulent measurements (e.g. water temperature in the boiler without an agitator)
