2. △

!CAUTION

● Before operating this instrument, familiarize yourself with all instructions

outlined in this manual.

● Always check to make sure that the function switch is set to the proper position.

● When making measurements, use CAUTION as dangerous voltages may be

present in normally safe areas.

● To avoid electrical shock, use CAUTION when working above 60V DC or 25V AC

rms.

Such voltages pose a shock hazard.

● Never make measurements with the case opened.

● Never fail to keep the maximum tolerable input.

● Never operate this instrument if it becomes wet, damp or has any liquid

condensation build-up on any part of the instrument.

● Never make measurements for uninsulated conductors or bus bars.

5-3. Measurement of AC Line Current

① Set the range selector switch to a range

appropriate to the current to be measured.

Start the measurement at top range and

then work down to lower range.

② Clamp the conductor of the circuit at the

center of CT.

③ If you make measurements in a dark place

or in a place where it is difficult to see the

readings,usethemeterlockfunction. Fig.1

Note : Clamp around only one conductor of the circuit to be measured. (See Fig.1)

△

!CAUTION

● To avoid electrical shock or damage, the measurement is limited to the circuit

under 600V AC and 600A AC.

5-4. Measurement of AC Voltage

① Connect the plug of red test lead into

the “V” terminal and the plug of black

test lead into the “COM” terminal.

② Set the range selector switch to “~300V”

or “~600V” range appropriate to the

voltage to be measured.

③ Contact the tips of the test leads to the

circuit under test.

④Readthevoltageonthescale. Fig.2

△

!WARNING

Do not make measurements of power lines carrying more than 250V.

IN SOME CASES, POWER LINES MAY CARRY VOLTAGE SPIKES OF

SEVERAL TIMES OF THE NORMAL SUPPLY VOLTAGE. THIS

INSTRUMENT SHOULD NOT BE USED TO MEASURE POWER LINES.

* The term of “Power Line” mean the electrical circuit providing the power

to factories, buildings, and etc.

△

!WARNING

POSSIBLE ELECTRICAL SHOCK. Do not make measurements if the case

is damaged or the rear case is removed. Remove all electrical inputs before

removing the rear case.

△

!WARNING

POSSIBLE ELECTRICAL SHOCK or FIRE HAZARD. Do not expose this

tester to rain or moisture. Do not operate the tester in the presence of

flammable gases or fumes.

△

!CAUTION

To avoid damage to the tester, disconnect test leads before changing

functions. Do not exceed the maximum input limits.

5-5. Measurement of DC Voltage

①Connect the plug of red test lead into the “V” terminal and the plug of black test

lead into the “COM” terminal.

②Set the range selector switch to “ …60V” range.

③Contact the tips of the test leads to the circuit under test.

④Readthevoltageonthescale.

5-6. Measurement of Resistance

① Connect the plug of red test lead into

the “Ω” terminal and the plug of black

test lead into the “COM” terminal.

② Set the range selector switch to “×100”

or “×1” range appropriate to the resistance

to be measured.

③Short the tips of test leads and adjust the

pointer to indicate zero with the zeroΩ

adjustment knob.

④Contact the tips of the test leads to the

circuit under test.

⑤Read the resistance on theΩscale.

For×100 range, read the resistance

value with 100 times.

!CAUTION

Be sure all voltage is turned OFF in the circuit before making resistance

measurement.

5-7. Measurement of Temperature

Temperature measurement is available with MT-3000 thermistor probe (optional

accessory). Please refer to MT-3000 instruction manual about the measuring method.

6. REPLACEMENT OF BATTERIES AND FUSE

Turn the power switch to "OFF", prior

to installing batteries or fuse.

To install the batteries or fuse, remove

the battery cover located on the unit back.

Loosen the screw on the battery cover.

Replace the two batteries (UM-4 or

type AAA) with new ones, observing

polarity. Use high-quality batteries

which are guaranteed against leakage.

If the instrument is to be left unused

for long periods of time, to prevent

damage from leakage, remove the batteries.

△

!WARNING

Before changing batteries or fuse, removal all electrical input.

7. MAINTENANCE

When making requests for repair service, please bring the instrument directly to the

dealer. If this is impossible, however, send the instrument directly to our sales office.

When mailing this instrument, always pack it in its original or equivalent packing

material and pack together with name, address, telephone number and the warranty

documentation.

● To ensure speedy and reliable repair, always include information as the type of

failure and cause.

● If required, always return accessories with the instrument.

● When contacting us, provide the model number and serial number of your
