Terms in this manual
WARNING identifies conditions and actions that could result in serious injury or even death to the user.
CAUTION identifies conditions and actions that could cause damage or malfunction in the instrument.
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. The meter is intended only for indoor use. The meter is protected by
double insulation per EN61010-1, IEC61010-1, CSA C22.2 No. 1010-1-92 and UL61010B-1 to CAT III 300V & CAT II 600V
(CAT II 450V for model AM-45).
Measurement Category III (CAT III) is for measurements performed in a 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.
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
and probes for damaged insulation or exposed metal before using the instrument. If any defects are found, replace them
immediately.
