I. 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. The meter is intended only for indoor use.
The meter protection rating, against the users, is double insulation
per IEC/UL/EN61010-1 Ed. 3.0, IEC/EN61010-2-030 Ed. 1.0,
IEC/EN61010-2-033 Ed. 1.0, IEC/UL/EN61010-031 Ed. 1.1 and
CAN/CSA-C22.2 No. 61010-1-12 Ed. 3.0 to Category II 1000 Volts,
CAT III 600Volts and CAT IV 300Volts AC & DC.
Terminals (to COM) measurement category:
V / A / mA
A:
Category II 1000V, Category III 600V and
Category IV 300V AC & DC.
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 over current
protection devices and ripple control units.
Per IEC61010-1 2nd Ed. (2001) Measurement Category
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 to the user.
CAUTION :
Identifies conditions and actions that could cause
damage or malfunction in the instrument.
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(s). Do not attempt a current measurement to any
circuit where the open circuit voltage is above the protection
fuse(s) voltage rating(s). 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(s) with the proper rating as
specified in this manual. Only use the test lead provided with the
equipment or UL Listed Probe Assembly.
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.
