4.5  Improving Probe Contact (Contact Improver Function)

47

4

Probe contacts can be improved by applying current from the POT to the CUR probes before mea-
suring.

The current used for the Contact Improver functions can be selected as follows.
17 mA, 25 mA, 35 mA (default), 50 mA
Higher current provides more effective contact improvement, but at the cost of faster probe deterioration.
Contact Improver current can be set to be disabled (OFF), enabled (ON), or PULSE.
The PULSE setting applies the contact improvement current for about 100 µs immediately before measure-
ment. The PULSE setting is usefull to decrease Joule heating if the DUT is susceptible to its current.

*: It takes several microseconds for the DUT current to reach the steady-state value. Until the steady-state

value is reached, a transient current that is approximately equal to the contact improvement current setting
(default setting: 35 mA) will flow.
