The measurement result includes the input cable resistance and contact resistance. To reject these re-
sistance effects, short the tip of the input cable and set the NULL calculation to ON before the mea-
surement.
Ensure the following when in the high-resistance measurement to reduce the effect of the induction
noise.
• Shielding the DUT.
• Using the A01001 input cable (sold separately) whose HI side is shielded.
• Securing the input cable to prevent movement.
