3.1 Pre-Operation Inspection
Before using the instrument, make sure
that the insulation on the test leads and
cables is undamaged and that no bare
conductors are improperly exposed.
Using the product in such conditions
could cause an electric shock, so contact
your dealer or Hioki representative for
replacements.
Make sure the terminals are clean and dry.
Wipe with a dry cloth to remove any
moisture, since measurement errors may
result if moisture is present.
See 8.2 "Cleaning" (page 154).
