  • Page 16: User Activated Safety Abort

    95x Series Operating Manual - May 17, 2022 When using high voltages, even if there is sufficient insulation, there may be significant capacitive coupling which can cause an unsafe current to flow to nearby objects and corona can occur even outside of the insulation. This is made worse by sharp corners on objects or the wiring.

    95x Series Operating Manual - May 17, 2022 LEAD COMPENSATION (4 -WIRE) Lead Compensation is not usually performed when using a 4-wire measurement since lead resistance is automatically eliminated. If a 4-wire test is configured but the DUT is connected in a 2-wire manner (e.g., separate wires for SOURCE and SENSE, but they are shorted together before the connection to the DUT) then a Lead Compensation may be performed in the same manner as for the 2-wire configuration above.
