Ill. Rules for Safe Operation
Please note the "Warning Signs and Words." Warnings
indicate the conditions and actions which pose hazards to
users or may damage the meter or equipment under test.
This Meter is designed to comply with the safety
standards, Conforms to UL STD. 61010-1, 61010-2-030, 61010
-2-032, 61010-2-033, Certified to CSA STD. C22.2 NO. 61010-1,
61010-2-030, IEC STD 61010-2-032, 61010-2-033 in pollution
degree 2, measurement category {CAT 111 1000v, CAT IV 600V)
and double insulation as well as with the IP65 standards
for waterproof and dustproof . If you use the meter without
following up the operating instructions, the protection provided
by the meter may be impaired or lost.
Measurement Category Ill (CAT Ill) 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 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.
1. Never use a damaged meter. Before using the meter, check
29
the meter case to see cracks or any missing plastic part.
Pay special attention to the insulation around the connectors.
2. Before using the meter, ensure the battery cover is closed
and latched. Before opening the battery cover, remove the
test leads from the meter.
3. Inspect the test leads for damaged insulation or exposed
metal. Check the test leads for continuity. If any test lead
is damaged, replace it before using the meter.
4. Do not apply more than the rated voltage, as marked on
the meter, between the terminals or between any terminal
and grounding.
5. Do not use the meter when removing the cover or opening
the case.
6. When the meter works at a voltage 30V (rms) in AC, 42V
(peak) in AC or over 60V in DC, special care should be
taken for there is danger of electric shock.
7. Replacement fuse must comply with the specifications in
this Operating Manual.
8. Use proper terminals, function and range for your
measurement. Do not operate the meter separately.
9. When measuring the current, shut off the power to the
circuit then connect the meter to the circuit. Remember:
The meter and the circuit must be connected in series.
10. When making electrical connections, connect the common
test lead before connecting the main test lead; when
disconnecting, disconnect the main test lead before
disconnecting the common test lead.
