COMPENSATION OF THE MEASURING CABLES

COMPENSA COMPENSATION OF THE MEASURING CABLES
IThere are 3 types of compensation for resistance of the measuring cables: "nOnE" (no compensation), "std"
(standard compensation for the cables delivered with the instrument: only the measuring cable with safety
plugs is counted), "uSEr" (user-defined compensation).
The default compensation is that of the measuring cable (standard compensation).
