1. Safety
This manual contains information and warnings that must be followed for operating the meter
safely and maintaining the meter in a safe operating condition. If the meter is used in a manner
not specified by the manufacturer, the protection provided by the meter may be impaired.
Observe proper safety precautions when working with voltages above 30 Vrms, 42.4 Vpeak or
60 VDC. These voltage levels pose a potential shock hazard to the user. Do not expose this
product to rain or moisture. The meter is intended only for indoor use.
Keep your hands/fingers behind the hand/finger barriers (of the meter and the test probe
assembly, where applicable) that indicate the limits of safe access of the hand-held parts during
measurements. Inspect lead wires, connectors, and probes for damaged insulation or exposed
metal periodically. 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.
Optional offer premium test probe assembly using silicone lead wire insulation, at agent’s
discretion, is equipped with white inner insulation layers as wear indicators. Replace them
immediately if any of the white layers has become visible.
Disconnect the test leads from the test points before changing functions.
The meter meets IEC/EN/BSEN/CSA_C22.2_No./UL standards of 61010-1 Ed. 3.0, 61010-2-030
Ed. 1.0, 61010-2-033 Ed. 1.0 to Measurement Categories CAT III 1000V and CAT IV 600V ac & dc.
The accompanied test probe assembly meets IEC/EN/BSEN/CSA_C22.2_No./UL standards of
61010-031 Ed. 2.0 to the same meter ratings or better. The 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 as well as on the add-on accessories (like detachable Caps
or Alligator Clips), if any, for applicable rating changes.
