4.11 Improving Probe Contact (Contact Improver Function)
90
Probe contacts can be improved by applying current from the SENSE A to the SENSE B
probes before measuring.
The maximum contact improvement current is 10 mA, and the maximum applied voltage is 5 V.
When low power is set to on, the contact improver function is set to off.
Using the contact improver function causes the time until measurement completion to be
lengthened by 0.2 ms.
