4.3 Compensating Measured Values (Scaling Function)
46
When measuring the resistance of current sensing resistors, there may be a discrepancy between
the resistance value at the time of mounting on the board being used and the resistance value
obtained when measuring the component alone (due to the effects of the probing location and other
factors). The scaling function corrects the measured resistance value obtained from the component
alone to yield the resistance value during actual use. Scaling is performed by mean of the following
equations:
R
S
= A × R + B
R : Measured value before compensation
R
S:
Resistance value after compensation
A : Compensation coefficient setting range: 0.50000 to 2.00000 (default:: 1.00000)
B : Offset resistance setting range: ±0.0000 m Ω to ±99.9999 M Ω (default: 0.0000 m Ω )
• Scaling calculation will be performed on a measured value after zero-adjustment. Consequently, measure
value may not be equal to zero after zero-adjustment.
• Changing the comparator settings automatically sets the scaling function to OFF.
