Safety
This manual contains information and warnings that must be followed for operating the
instrument safely and maintaining the instrument in a safe operating condition. If the
instrument is used in a manner not specified by the manufacturer, the protection provided by
the instrument may be impaired.
To avoid electrical shock hazard, observe the proper safety precautions when working with
voltages above 60 VDC or 30 VAC rms. These voltage levels pose a potential shock hazard to
the user.
Keep your hands/fingers behind the hand/finger barriers (of the meter and the test leads) that
indicate the limits of safe access of the hand-held part during measurement. Inspect test
leads, connectors, and probes for damaged insulation or exposed metal before using the
instrument. If any defects are found, replace them immediately. Only use the test probe
assembly provided with the meter or a UL Listed test probe assembly to the same meter
ratings or better.
This Clamp-on meter is designed to apply around or remove from uninsulated hazardous live
conductors. But still, individual protective equipment must be used if hazardous live parts in
the installation where measurement is to be carried out could be accessible.
Disconnect the test leads from the test points before changing functions.
The meter protection rating, against the users, is double insulation per IEC/EN/UL/CAN/CSA
C22.2 No. 61010-1 Ed. 3.1, IEC/E/UL/CAN/CSA C22.2 61010-2-032 Ed. 4.0 Measurement
Categories CAT IV 1000V and CAT III 1500V dc for Photovoltaic Power Generation applications.
The accompanying test probe assembly meets IEC/EN/UL/CAN/CSA C22.2 No.standards of
61010-031 Ed. 2.0 to the same meter ratings or better. The IEC/EN/UL/CAN/CSA C22.2 No.
61010-031 requires exposed conductive test probe tips to be ≤ 4mm for CAT III & CAT IV ratings.
Refer to the category markings on your probe assemblies and the add-on accessories (like
detachable Caps or Alligator Clips), if any, for applicable rating changes.
