Measurement Category III (CAT III) is for measurements performed in the
building installation. Examples are measurements on distribution boards,
circuit- breakers, wiring, including cables, bus-bars, junction boxes, switches,
socket-outlets in the fixed installation, and equipment for industrial use
and some other equipment, for example, stationary motors with permanent
connection to the fixed installation.
Measurement Category II (CAT II) is for measurements performed on circuits
directly connected to the low voltage installation. Examples are measurements
on household appliances, portable tools and similar equipment.
Terms In This Manual
�WARNING
serious injury or even death to the user.
�CAUTION
or malfunction in the instrument.
�WARNING -
this product to rain or moisture.
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 fingers behind the finger guards of the test leads 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.
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.
�CAUTION -
changing meter functions. Only use the accompanied test leads, or
replace with the same rating or better UL Listed Probe Assembly.
