I. SAFETY :
Terms in this manual :
WARNING :
Identifies conditions and actions that could result in
serious injury or even death to the user.
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.
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.
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.
The meter meets UL/IEC/EN61010-1 Ed. 3.0, CAN/CSA C22.2 No.
61010-1 Ed. 3.0, UL/IEC/EN61010-2-033 Ed. 1.0 to Measurement
CAT-III 1kV and CAT-IV 600V, AC & DC.
The accompanied test probe assembly meets UL/IEC/EN61010-
031 Ed. 1.1 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.

02
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.
CAUTION
Disconnect the test leads from the test points before changing
functions.
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 Categories
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,
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.
Measurement Category II
is applicable to test and measuring
circuits connected directly to utilization points (socket outlets and
similar points) of the low-voltage MAINS installation. Examples are
measurements on MAINS CIRCUITS of household appliances,
portable tools and similar equipment.
