1. Connect the black test lead to the " COM " jack and the

red test lead to the " INPUT " jack.

2. Set the range switch to desired range.

3. Connect the test leads across the circuit or source to be measured.

4. Read the reading on the display. The polarity of the red

lead connection will be indicated as well.

Note :

To avoid damages to the meter, do not attempt to measure a

DC voltage higher than 35V although readings may be

obtained.

1. Connect the black test lead to the " COM " jack and the

red test lead to the " 10A " jack.

2. Set the range switch to position.

3. Turn off power to the circuit which you want to measure.

Discharge all capacitors.

4. Break the circuit path to be measured, connect the test

leads in series with the circuit.

5. Turn on power to the circuit, then read the display. The

polarity of the red test lead connection will be indicated as

well.

1. Connect the black test lead to the " COM " jack and the

red test lead to the " INPUT " jack. ( Note:The polarity of

the red lead is positive " + ". )

2. Set the range switch to desired range.

3. Connect the test leads across the load to be measured.

4. Read the reading on the display.

1. Connect the black test lead to the " COM " jack and the

red test lead to the " INPUT " jack. ( Note:The polarity of

the red lead is positive " + ". )

2. Set the range switch to position.

3. Connect the test leads to the circuit to be measured.

4. If the resistance is less than about 30 , the built-in buzzer

will sound.

1. Connect the black test lead to the " COM " jack and the

red test lead to the " INPUT " jack.

2. Set the range switch to 20kHz position.

3. Connect the test leads across the source or load to be

measured.

4. Read the reading on the display.

1. Connect the black test lead to the " COM " jack and the

red test lead to the " INPUT " jack. ( Note:The polarity of

the red lead is positive " + ". )

2. Set the range switch to position.

3. Connect the red test lead to the anode of the diode to be

tested and the black test lead to the cathode of the diode.

4. The display shows the approximate forward voltage drop of the diode. If the connection is reversed, "1" will be shown on the display.

1. Connect the black test lead to the " COM " jack and the

red test lead to the " INPUT " jack.

2. Set the range switch to Duty position.

3. Connect the red test lead to the positive terminal of the

signal source be measured and the black test lead to the negative terminal of the signal source.

4. Read the reading on the display.

1. Connect the negative " - " plug of the K type

thermocouple to the " COM " jack and the positive " + "

plug of the K type thermocouple to the " INPUT " jack.

2. Set the range switch to °C position.

3. Connect the sensing end of the thermocouple to the

object to be measured.

4. Wait until the reading is stable, then read the reading.

1. Connect the black test lead to the " COM " jack and the

red test lead to the " INPUT " jack.

2. Set the range switch to desired DWELL position

according to the cylinder number of the engine to be

measured.

3. Connect the black test lead to ground or the negative

terminal of the battery, and connect the red test lead to

the low voltage terminal of the distributor or the negative

terminal of the ignition coil.

4. Start the engine and read the reading on the display.

1. Connect the black test lead to the " COM " jack and the

red test lead to the " INPUT " jack.

2. Set the range switch to desired TACH position

according to the cylinder number of the engine to be measured.

3. Connect the black test lead to ground or the negative

terminal of the battery, and connect the red test lead to

the low voltage terminal of the distributor or the negative

terminal of the ignition coil.

4. Start the engine. Read the reading on the display and

then multiply this reading by 10 to get the final measurement result.

1. Connect the black test lead to the " COM " jack and the

red test lead to the " INPUT " jack.

2. Set the range switch to desired BAT. position according

to the rated voltage of the battery to be tested.

3. Connect the black test lead to the negative terminal of the

battery and the red test lead to the positive terminal of the

battery.

4. If the " Low " LED lights, the battery is low.

If the " Normal " LED lights, the battery is normal.

If the " High " LED lights, the battery is high.
