Cleaning HP 16442A Test Fixture

To maintain high performance, HP 16442A must be kept clean. Oil, perspiration, hair, dust,
and dirt degrade board insulation, which increases leakage current and decreases measurement
accuracy.

Hewlett-Packard recommends the following cleaning procedure:

Chassis, lid, inner plate, and socket modules:

1. Make sure that voltage or current is

not

forced to HP 16442A.

2. Disconnect all cables from HP 16442A.

3. Using lint-free paper, gently wipe the chassis, lid, inner plate, and socket module. For

any area that will not come clean, dip the lint-free paper into alcohol and wipe the area
gently.

Connection cables:

1. Make sure that voltage or current is

not

forced to HP 16442A.

2. Disconnect the connection cables from HP 16442A.

3. Dip lint-free paper into alcohol and gently wipe the metal contacts of the connection

cables.
