Monitoring of DC analog measurements
Where:
I_Min is the set value for the minimum operating current of a channel in mA.
I_Max is the set value for the maximum operating current of a channel in mA.
ValueMin is the value of the primary measuring quantity corresponding to the set value of
minimum operating current of a channel, I_Min.
ValueMax is the value of the primary measuring quantity corresponding to the set value of
maximum operating current of a channel, I_Max.
Value is the actual value of the primary measured quantity.
Figure 198 shows the relationship between the direct mA current I and the actual value
of the primary measured quantity, Value.
