A : Category III 1000 Volts AC & DC, and Category IV 600 Volts AC & DC.

Per IEC 61010-1 3rd Ed. Measurement Category

Measurement Category IV (CAT IV) is for measurements performed at the

source of the low-voltage installation. Examples are electricity meters and

measurements on primary overcurrent protection devices and ripple control

units.

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.

WARNING

�

To reduce the risk of fire or electric shock, do not expose 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. Do not

touch test lead tips or the circuit being tested while power is applied to the

circuit being measured. 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. Only use

the accompanied test leads, or replace with the same rating or better.
