Operating Precautions
6
Follow these precautions to ensure safe operation and to obtain the full benefits of
the various functions.
• Before using the instrument for the first time, verify that it operates normally to
ensure that no damage occurred during storage or shipping. If you find any dam-
age, contact your dealer or Hioki representative.
• Before using the instrument, make sure that the insulation on the cables is undam-
aged and that no bare conductors are improperly exposed. Using the instrument in
such conditions could cause an electric shock, so contact your dealer or Hioki rep-
resentative for replacements.
• Operating temperature and humidity: 0 to 40°C at 80% RH or less (non-conden-
sating)
• Temperature and humidity range for guaranteed accuracy: 23±5°C, 80%RH or
less
