MAINTENANCE
Take care of the condition of antenna input adapter and any test leads you use.
Quality connectors and test leads are a sound investment in long reliable analyzer life.
Clean Annually; remove your DAT103 from its soft plastic holster, hold upside down
and brush gently with a small dry horsehair or similar brush - so that any foreign materials
fall away. Wipe thoroughly with a moist cloth. Cleaning products should be tested on a
small unobtrusive area to ensure the product does not damage the analyzers finish, and
then used sparingly. Wipe over the plastic holster, inside and out. Allow the Analyzer and
holster to dry slowly before reassembling.
Take care to keep coax braid wire cuttings away from your Analyzer. Just one piece
inside your meter can be expensive to locate and may even cause permanently damage.
