These are defined as follows. CAT II :Primary electrical circuits in equipment connected to an AC electrical outlet by a power cord portable tools, household appliances, etc. CAT II covers directly measuring electrical outlet receptacles. CAT III:Primary electrical circuits of heavy equipment fixed installa- tions connected directly to the distribution panel, and feeders from the distribution panel to outlets.
CAT IV:The circuit from the service drop to the service entrance, and to the power meter and primary overcurrent protection device distribution panel. Follow these precautions to ensure safe operation and to obtain the full benefits of the various functions. Preliminary Checks Before using the instrument the first time, verify that it operates normal- ly to ensure that no damage occurred during storage or shipping.
If you find any damage, contact your dealer or Hioki representative. Please refer to the Specifi- cations for the rating performance of this instrument. The instrument may be damaged or cause an explosion. Contact with these substances may cause cracking in the instrument, resulting in damage or elec- tric shock. This may cause an electric shock. Any other elec- trical supply may damage the instrument and tested object and cause electric shock.
Using the instrument in such conditions could cause an electric shock, so contact your dealer or Hioki representative for replacements. Under such conditions, the instrument may be damaged and insulation may deteriorate so that it no longer meets specifications. Be especially careful to avoid phys- ical shock from dropping. To prevent possible damage, avoid using in dusty or wet environments.
To prevent a short circuit accident, be sure to use the test leads with the sleeves attached when performing measurements in the CAT III measurement category.
Remove the sleeves from the test leads when performing measurements in the CAT II measure- ment category. For details on measurement categories, see "Mea- surement categories" in the instruction manual.
If the sleeves are inadvertently removed during measurement, be especially careful in handling the test leads to avoid electric shock. If a color inside the cable is exposed, do not use the cable. The equipment inside the enclosure is protected against entry by solid foreign objects larger than 1. Battery may drain if the switch is not turned to OFF. Please remove this cap before attaching it to the instrument. The cover will not close if the switch is not at OFF.
