For more information about the contact improver function, see p.90.
Probe contacts can be improved by applying current between the sense terminals before
measurement.
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 con-
tact improver function causes the time until measurement completion to be lengthened by 2
ms.
