d. Any abnormal operation is detected.

(If in doubt about the condition of the meter, have it serviced.) e. The battery cover is open.

4. This meter should be powered only by a single, correctly installed 9V battery.

5. Use caution when working near voltages above 30 VAC rms, 42 VAC peak, or 60 VDC. Voltages this high present a risk of electric shock.

6. Disconnect the circuit’s power before connecting the meter in series, when measuring current.

7. Connect the common (COM) test lead first and disconnect it last.

8. Hold the probes with fingers behind guards.

9. Avoid electrical shock. Use extreme caution when working near uninsulated conductors or bus bars. Prevent body contact with grounded surfaces such as pipes, radiators, ranges, and cabinet enclosures when testing voltages.

10. Observe work area conditions. Do not test voltages in damp or wet locations. Don’t expose to rain.

Keep work area clean and well lit.

11. Keep children away. Children must never be allowed in the work area.

12. Stay alert. Watch what you are doing, use common sense. Do not operate any meter when you are tired.

13. Do not operate meter if under the influence of alcohol or drugs. Read warning labels on prescriptions to determine if your judgment or reflexes are impaired while taking drugs. If there is any doubt, do not operate the meter.

14. WARNING: This product contains lead, a chemical known to the State of California to cause cancer and birth defects or other reproductive harm. (California Health &

Safety Code § 25249.5,

General Operating Instructions

Ac Voltage Measurements

Measure AC conductors carrying up to 700 VAC, 45-450 Hz.

1. Turn the Range Selector Switch to

700 ACV setting. Start with the highest range if the voltage is unknown.

2. Plug the red lead into the V/Ω/Hz Jack.

Plug the black lead into the COM

Jack. Switch the Multimeter ON.

3. Carefully touch the exposed conductors with the tips of the probes to measure the voltage (not amperes).

4. Read measurement. If the voltage is less than 200 volts, set the Range

Selector Switch to the lower range.

5. When testing is complete, remove

Test Leads and store with multimeter.

Dc Voltage Measurements

Measure DC conductors carrying up to 1000 VDC.

1. Turn the Range Selector Switch to 1000 DCV setting.

Ac current Measurements

Measure AC conductors carrying up to 20 amperes.

1. Turn the Range Selector Switch to the

20A~ position. Start with the highest range if the amperage is unknown.

2. Plug the red lead into the 20A

Jack. (For current under 20A, plug the red lead into the mA Jack.)

Plug the black lead into the COM

Jack. Switch the Multimeter ON.

2. Follow the directions above under

“AC Voltage Measurements”, only use the DC settings instead.

3. Carefully touch the exposed conductors with the tips of the probes to measure the amperage.

Note:

Amperage is always tested in series with the circuit under test.

4. Read measurement. If the reading is less than 0.2 amps, switch the red lead to the VΩmA Jack and set the Range

Selector Switch to the 200 mA setting.

5. When testing is complete, remove

Test Leads and store with multimeter.

Dc current Measurements

Measure DC conductors carrying up to 20 amperes.

1. Turn the Range Selector Switch to the

20A position. Start with the highest range if the amperage is unknown.

2. Follow the directions above under

“AC Current Measurements”, only use the DC settings instead.

Item 37772 61593

Resistance Measurements

Measure circuit resistance up to 20M Ohms.

WARNING!

Do not measure resistance on circuit with voltage running through it.

Notice:

When measuring Ohms, start with the lowest range if the resistance is unknown.

1. Turn the Range Selector Switch to the 200Ω position.

2. Plug the red Test Lead into the V/Ω/

Hz Jack. Plug the black Test Lead into the COM Jack. Switch the Multimeter

ON. Short the Test Leads together.

The meter should read “0” Ohms.

3. Touch the exposed conductors with the tips of the Test Leads.

4. Read measurement. If the reading is

“1”, set the Range Selector Switch to the next higher Ohm (Ω) position.

5. When measuring resistance above 1

MΩ, the meter may take a few seconds to give a stable reading. This is normal for high resistance measurements.

6. At the 20MΩ range, the display reading will be around 0.1 counts over the actual measurement. These counts should be subtracted from the resulting reading. For example, when measuring

10 MΩ resistance, the display will read

10.1, but the correct measurement should be 10.1-0.1=10.0MΩ

7. Remove and store Test Leads.

capacitance Measurements

Measure capacitance up to 20μF.

1. Turn the Range Selector Switch to the

20μF position. Start with the highest range if the capacitance is unknown.

WARNING!

Fully discharge capacitor before measuring.

2. Plug capacitor into the capacitance testing socket (Cx).

Switch the Multimeter ON.

3. Read measurement. If the reading is less than 20μF, set the Range

Selector Switch to a lower range.

WARNING!

Avoid electric shock.

Remove capacitor before switching between testing modes.

Frequency Measurements

Measure frequency up to 20kHz.

1. Turn the Range Selector Switch to the 20kHz position.

2. Plug the red Test Lead into the V/Ω/Hz

Jack. Plug the black Test Lead into the

COM Jack. Switch the Multimeter ON.

Note:

Reading is possible at input voltages above 10Vrms, but the accuracy is not guaranteed.

Note:

In noisy enviroments, use a shield cable to measure smaller signals.

3. Remove and store Test Leads.

1. Turn the Range Selector Switch to the hFE position. Switch the Multimeter ON.

2. Insert transistor pins into the appropriate holes of the hFE testing socket (NPN or PNP) according to the EBC (Emitter,

Base, Collector) sequence.

Temperature Measurement

1. Turn the Range Selector Switch to the TEMP position. Switch the

Multimeter ON. Display will show the current ambient temperature.

2. Plug a “K”-type thermocouple into the temperature measuring socket.

3. The meter will show the approximate hFE value at the test condition of base current 10μA and Vce 3.2V.

4. Remove and store Transistor.

Diode Measurement

Test the voltage drop in diodes.

1. Turn the Range Selector Switch to the Diode ( ) position.

2. Plug the red Test Lead into the V/Ω/Hz

Jack. Plug the black Test Lead into the

COM Jack. Switch the Multimeter ON.

3. Connect red probe to the anode of the diode and the black to the cathode.

4. The approximate forward voltage drop of the diode will be displayed in mV. If the connection is reversed, only “1” will be shown.

5. Remove and store Test Leads.

continuity Measurement

Test continuity between two points of a circuit.

1. Turn the Range Selector Switch to the position. Switch the Multimeter ON.

2. Connect Test Leads to two points of the circuit. If continuity exists

(i.e., resistance is less than

50Ω), a buzzer will sound.

3. Remove and store Test Leads.

3. Contact object to be measured with the thermocouple probe.

Read measurement.

WARNING!

Avoid electric shock.

Remove thermocouple before switching between testing modes.
