4.4 Compensating for Thermal EMF Offset (Offset Voltage
Compensation Function: OVC Function)
This function automatically compensates for an offset voltage caused by
thermal EMF or an internal offset voltage.
(OVC: Offset Voltage Compensation)
See: “Appx. Effect of Thermoelectromotive Force (Thermal EMF)”.
The function uses the resistance value measured when a measurement
current flows, RP and that measured when no measurement current flows, RZ,
to display the actual resistance value RP-RZ.
