Lets you custom correct reading of the main input by setting four values: A1, B1, A2, B2.
This function is enabled by setting "Sens" +8 code ("Hrd" menu).
Example: Sens = 1+8 = 9 for RTD probe with input correction.
The scale can be reversed if this function is applied to linear scales (50mv, 10V, 20mA, Pot).
The four values are set on the "Lin" menu as follows: A1 = St100, B1 = St01, A2 = St02, B2 = St03. Setting is limited to the defined scale ("LoS"
... "HiS" on "InP" menu).
The offset function ("oFt" parameter on "InP" menu) remains enabled.
Limits:
B1 always greater than A1;
B1-A1 at least 25% of full scale of selected probe.
Example:
Sens = 9, TyPE = 0 (Pt100 natural scale -200...+600), dPS = 0
LoS = 0, HiS = 400, oFt = 0
Reference point on real curve:
Corresponding points on corrected curve: A2 = St02 = 120, B2 = St03 = 220

These transformers are used to measure currents
of 50 ÷ 60Hz from 25A to 600A
(nominal primary current). The peculiar
characteristic of these transformers is the high
number of secondary turns. This provides a very
low secondary current, suitable for an electronic
measurement circuit. The secondary current may
be detected as voltage on a resistor.
