SAFETY INFORMATION
The Meter complies with:
IEC/EN 61010-1 3rd Edition, UL61010-1 2nd Ed. and CAN/CSA C22.2 No.
61010.1-0.92 to Category III 600 Volts, Pollution degree 2
IEC/EN 61010-2-030
IEC/EN 61010-2-31 for test leads
EMC IEC/EN 61326-1
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.
2
Measurement Category II (CAT II) iis for measurements performed on circuit
directly connected to low voltage installation. Examples are measurements on
household appliances, portable tools and similar equipments.
Warning: Read Before Using
• To avoid possible electrical shock or personal injury, follow these
instructions and use the Meter only as specied in this manual.
• Do not use the Meter or test leads if they appear damaged, or if
the Meter is not operating properly. If in doubt, have the Meter
serviced.
• Always use the proper function and range for measurements.
• Before rotating the function range selection switch, disconnect
test probe from circuit under test.
• Verify the Meter’s operation by measuring on a known voltage
source.
• Do not apply more than the rated voltage, as marked on the
Meter, between the test probe or between any test probe and
earth ground.
• Use the Meter with caution for voltages above 30 Vac rms, 42 Vac
peak, or 60 Vdc. These voltages pose electrical shock hazards.
• Disconnect circuit power and discharge all high-voltage capacitors
before testing resistance.
• Do not use the Meter around explosive gas or vapor.
• When using the test leads, keep your ngers behind the nger
guards.
• Remove test leads from the Meter before opening the Meter case
or battery door.

Meter, disconnect circuit power and discharge all high-voltage capacitors
before testing resistance and diode.
3. Connecting test leads:
• Connect the common (COM) test lead to the circuit before connecting
the live lead;
• After measurement, remove live lead before removing the common
(COM) test lead from the circuit
4. Symbol “OL” is displayed on LCD when the measurement is out of range.
