emergency condition.

For highly accurate current forcing and measurements while minimizing leakage, surround all force and sense lines from SMU by a guard as far as possible, and make cables stable by taping.

For reducing capacitance measurement error, tape the cables to any grounded materials such as shielding box. If you use probe card, grounding the probe card also reduces capacitance measurement error.
