2. Safety
Safety Notes
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.
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.
The meter is intended only for indoor use.
Keep your hands/fingers behind the hand/finger barriers (of the meter and the test
probe assembly, where applicable) that indicate the limits of safe access of the hand-held
parts during measurements. Inspect lead wires, connectors, and probes for damaged
insulation or exposed metal before using the meter. If any defects are found, replace
them immediately. Only use the probe assembly provided with the meter or a UL Listed
Probe Assembly to the same meter ratings or better.
IEC 61010-031 requires exposed conductive test probe tips to be ≤4mm for CAT III & CAT
IV ratings. Refer to the category markings on your probe assemblies as well as on the
add-on accessories (like detachable Caps or Alligator Clips), if any, for applicable rating
changes.
Observe proper safety precautions when working with voltages above 33 Vrms, 46.7
Vpeak or 70 VDC. These voltage levels pose a potential shock hazard to the user. Before
and after hazardous voltage measurements, check the voltage function on a known
source such as line voltage to determine proper meter functioning.
CAUTION
Disconnect the test leads from the test points before changing functions.

Measurement Categories
Measurement Category IV is applicable to test and measuring circuits connected at
the source of the building’s low-voltage MAINS installation. Examples are
measurements on devices installed before the main fuse or circuit breaker in the
building installation.
Measurement Category III is applicable to test and measuring circuits connected to
the distribution part of the building’s low-voltage MAINS installation. Examples are
measurements on distribution boards (including secondary meters), circuit-breakers,
wiring, including cables, bus-bars, junction boxes, switches, and socket-outlets in the
fixed installation, and equipment for industrial use and some other equipment such as
stationary motors with permanent connection to the fixed installation.
CENELEC DIRECTIVES
The instruments conform to CENELEC Low-voltage directive 2014/35/EC,
Electromagnetic compatibility directive 2014/30/EU and RoHS directive 2011/65/EU.
