*1 About zero-adjustment
Perform zero-adjustment in the following circumstances:
• The measured value is not cleared due to thermal EMF or other factors.
The measured value will be adjusted to zero. (Accuracy is not affected by whether or
not the zero adjustment is performed.)
• Four-terminal connection (called Kelvin connection) is difficult.
The residual resistance of the two-terminal connection wires will be canceled.
