Operating Precautions
Operating Precautions
Observe the following precautionary information to ensure that the
instrument can be used safely and in a manner that allows it to
perform as described in its specifications.
Use of the instrument should confirm not only to its specifications,
but also to the specifications of all accessories, options, batteries,
and other equipment in use.
DANGER
• For your safe operation, do not connect any test
lead to the primary of the distribution panel.
• Do not short-circuit two wires to be measured by
bringing the test leads into contact with them. Arcs
or such grave accidents are likely to occur.
• To avoid short circuit or electric shock, do not touch
the metal part of the connecting test lead tip.
• To avoid electric shock, be careful to avoid shorting
live lines with the test leads tip.
If the test lead or the instrument is damaged, there
is a risk of electric shock. Perform the following
inspection before using them:
• Before using the instrument check that the coating
of the test leads are neither ripped nor torn and that
no metal parts are exposed. Using the instrument
under such conditions could result in electric
shock. Replace the test leads with those specified
by Hioki.
• Verify that the instrument operates normally to
ensure that no damage occurred during storage
or shipping. If you find any damage, contact your
authorized Hioki distributor or reseller.
