• CURRENT TRANSFORMERS
18 • ACCESSORIES
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.

17 • MAIN INPUT CORRECTION FUNCTION
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: A1 = St00 = 50, B1 = St01 = 350 (B1-A1 = 300, greater than 25% of 800)
Corresponding points on corrected curve: A2 = St02 = 120, B2 = St03 = 220
A1=50 200 B1=350 400
