DANGER
If the test lead or the instrument is damaged, there is
a risk of electric shock. Before using the instrument,
perform the following inspection.
• 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 electrocution. Replace
the test leads with those specifi ed by our company.
• To avoid electric shock, check that the white or
red portion (insulated layer) within the cable is not
exposed. Do not use the cable if its internal colored
portion is exposed.
• Before using the instrument the fi rst time, verify that it
operates normally to ensure that no damage occurred
during storage or shipping. If you fi nd any damage,
contact your authorized Hioki distributor or reseller.
