Cleaning
To maintain high performance, the 16442B test fixture (B1500A-A5F) must be kept
clean. Oil, perspiration, hair, dust, and dirt degrade board insulation, which
increases leakage current and decreases measurement accuracy.
Keysight Technologies recommend the following cleaning procedure:
• Chassis, lid, inner plate, and socket modules:
1. Make sure that voltage or current is not forced to the 16442B.
2. Disconnect all cables from the 16442B.
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 the 16442B.
2. Disconnect the connection cables from the 16442B.
3. Dip lint-free paper into alcohol and gently wipe the metal contacts of the
connection cables.
