4.5  Improving Probe Contact (Contact Improver Function)

48

For ranges between 1000 k

 and 100 M

, the [PULSE] setting is enabled by default. 

Before measuring in the ranges from 1000 k

 to 100 M

 with the Contact Improver function set to [ON], verify

that measurements are not biased.

1

Open the Basic Settings screen.

2

Open the Measurement Settings Screen.

3

Set the Contact Improver current timing to disabled (OFF), enabled (ON), or PULSE.

(When selecting ON or PULSE)

Set the current limit value.

4

Return to the Measurement screen.

The Basic Settings screen appears.
