If a
Mapped
input type is selected, additional fields appear to define the correspond-
ence between the input signal and a physical quantity.
Select the unit of measurement and the resolution of the physical quantity associated
to the input. Enter in the fields
X1 , X2 , Y1 and Y2 the coordinates of the linear relation
between the input signal and the physical quantity:
X1
= value of input signal in the first point (e.g. 4.00 mA)
Y1 = value of the physical quantity corresponding to the input value X1 (e.g. 0.0 °C)
X2
= value of input signal in the second point (e.g. 20.00 mA)
Y2 = value of the physical quantity corresponding to the input value X2 (e.g. 70.0 °C)

Press the key
Set
to apply to the measure an offset equal to the opposite of the cur-
rently measured value (the current measure becomes equal to zero). Press the key
Clear
to cancel the applied offset.
If a Mapped input type is selected, the data logger doesn’t store the input value in V
or mA, but the corresponding value of the physical quantity associated to the input.
