1) 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.
The meter is intended only for indoor use.
The meter protection rating, against the users, is double insulation per IEC61010-1 2nd Ed.,
EN61010-1 2nd Ed., UL61010-1 2nd Ed. and CAN/CSA C22.2 No. 61010.1-0.92 to Category III 1000
Volts AC & DC and Category IV 600 Volts AC & DC.
MM560A Terminals (to COM) measurement category:
V : Category III 1000 Volts AC & DC, and Category IV 600 Volts AC & DC.
A / mAA : Category III and Category IV 600 Volts AC and 300 Volts DC.
MM570A Terminals (to COM) measurement category:
V / A / mAA : Category III 1000 Volts AC & DC, and Category IV 600 Volts AC & DC.
Per IEC61010-1 2nd Ed. (2001) 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.
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 identifies conditions and actions that could result in serious injury or even death

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. Do not measure any current that exceeds the current rating of the
protection fuse. Do not attempt a current measurement to any circuit where the open circuit voltage is
above the protection fuse voltage rating. Suspected open circuit voltage should be checked with
voltage functions. Never attempt a voltage measurement with the test lead inserted into the A/mA or
A input jack. Only replace the blown fuse with the proper rating as specified in this manual.
CAUTION
Disconnect the test leads from the test points before changing functions. Always set the instrument to
the highest range and work downward for an unknown value when using manual ranging mode.
