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.
X�Warning: Read Before Using
• To avoid possible electrical shock or personal injury, follow these
instructions and use the Meter only as specified 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 fingers behind the finger guards.
• Remove test leads from the Meter before opening the Meter case or
battery door.

MAKING MEASUREMENT
X�
1. Use the proper function and range for measurements.
2. To avoid possible electrical shock, personal injury or damages to the
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.

MAINTENANCE AND REPAIR
If the Meter fails to operate, check battery, test leads, etc., and replace as
necessary.
Double check the followings:
1. Replace the fuse or battery if the meter does not work.
2. Review the operating instructions for possible mistakes in operating
procedure.
Quick check on 0.5A FUSE:
Step 1: Turn the rotary switch to Ω function.
Step 2: short-circuit E/V/Ω/Hz terminal and mA/μA terminal.
Resistance reading ≤ 1MΩ: the fuse is OK
Resistance reading “OL”: the fuse is open. Replace the fuse as specified.
Quick check on 10A FUSE:
Step 1: Turn the rotary switch to Ω function.
Step 2: short-circuit E/V/Ω/Hz terminal and A terminal.
Resistance reading ≤ 0.5Ω: the fuse is OK.
Resistance reading “OL”: the fuse is open. Replace the fuse as specified.
17
Except for the replacement of the battery, repair of the meter should be
performed only by a Factory Authorized Service Center or by other qualified
instrument service personnel.
The front panel and case can be cleaned with a mild solution of detergent and
water. Apply sparingly with a soft cloth and allow to dry completely before
using. Do not use aromatic hydrocarbons, Gasoline or chlorinated solvents for
cleaning.
BATTERY AND FUSE REPLACEMENT
X�WARNING
To avoid shock, injury, or damage to the Meter:
Disconnect test leads before opening case.
