Care and Service
• Keep your meter dry and clean. If it gets wet or dirty, wipe it dry or clean immediately with a cloth lightly dampened with water. Do not use harsh chemicals, cleaning solvents, or strong detergents to clean the meter.
• Use and store the meter in normal temperature environments only. Handle your meter carefully. Do not drop it.
• Modifying or tampering the meter’s internal components can cause malfunction and might invalidate its warranty. If your meter is not performing as it should, take it to your local RadioShack store for assistance.

Safety Precautions
• Do not use the meter if you are unfamiliar with electric circuits and testing procedures.
• To avoid electric shock, disconnect both test leads from the circuit under testing before you replace the batteries and fuse.
• Do not operate the meter until the batteries are properly installed and the back cover and battery compartment cover are in place and secured.
• Use extreme caution when working with voltages above 30V RMS and 42.4V peak or 60V
DC. Always disconnect power from the circuit you are measuring before you connect test leads to high-voltage points.
• Never connect to a voltage source when you select the diode check, continuity function, resistance measurement, or any of the battery test or current measurement functions.
• Always discharge any capacitors of the circuit under test before you attach test leads and always turn off power and disconnect the test leads from the circuit before replacing the meter’s batteries or the fuse.
• Because many AC/DC sets have a potentially hot chassis, be sure the top of your workbench and the floor underneath it are made of nonconductive materials.
• If you connect one test lead to a hot wire first and touch the other test lead tip, you could receive an electric shock.
4
• The test leads (black and red) supplied with your meter are rated for 1000 volts but do not try to measure any voltage greater than 600 volts DC/600 volts RMS AC. Use only test leads of the same rating as the meter.
• Your multimeter is designed primarily to measure household AC voltages. Because of the dangers inherent in measuring three-phase circuits, WE STRONGLY RECOMMEND
YOU DO NOT USE THIS METER TO MEASURE 3-PHASE, LINE-TO-LINE VOLTAGE .
If you still want to, put on protective clothing – a face shield and fireproof gloves and upper body protection is required before measuring. If you do not have this protection,
DO NOT MEASURE THESE CIRCUITS.
• To reduce the risk of fire or shock hazard, do not expose this product to rain or moisture.
For indoor use only.
• If this equipment is used in a manner not specified by the manufacturer, the protection provided by the equipment may be impaired.
• For the most accurate reading, the temperature should be between 65°F and 83°F (18°C to 28°C), with a maximum of 75% relative humidity.

Install the Batteries
Before installing batteries, turn off the multimeter and disconnect the test leads. Install three AAA batteries (not included), matching the polarity symbols (+ and -) marked inside. When appears, replace the batteries.
• Dispose of batteries promptly and properly. Do not burn or bury them.
• Use only fresh batteries of the required size and type.
• If you do not plan to use the meter for a month or more, remove the batteries. Batteries can leak chemicals that can damage electronic parts.

Basic Operation
Selecting Ranges
Set the meter to a measurement range; the unit of measure appears on the display. For example, mV appears in the 400 mV range.
Note the position of the decimal:
• If 0.000V appears, the meter is set to measure less than
4 volts.
• If 000 V appears, the meter is set to measure up to 600 volts.
Read the range in volts, amps, or ohms as indicated by the position of the decimal point.

Caution:
• If you are measuring voltage or current when OF (overflow) appears, immediately disconnect the test leads from the circuit.
• When measuring high-voltage circuits, do not position both test leads at once. Connect the black test lead first to the circuit’s neutral or ground lead. Then, using one hand, probe for voltages with the other test lead. This helps prevent accidentally touching a hot wire.
Measuring DC/AC Voltage
DO NOT try to measure voltages above 600 V DC/AC (RMS).
1.
Set the function dial to V .
2.

Measuring AC Voltage Riding on a DC Source Bias
Warning: T o avoid injury or damage to your meter, never try to measure an AC voltage on a DC source bias where the peak AC voltage exceeds 100V with respect to earth ground.
1.
Set the function dial to V ( DC voltage) . Measure the DC voltage first to ensure that it does not exceed 100V .
2.
Disconnect power from the circuit.
3.
Press SELECT (AC mode). appears.
4.
Connect the black test lead to the circuit’s neutral/ground lead.
5.
Connect a 0.1 microfarad/100V mylar capacitor in series with the voltage source’s positive terminal and the red test lead.
6.
Restore circuit power and read the voltage.
7 Power off the circuit; then disconnect the capacitor.

Measuring DC/AC Current
1.
Disconnect power from the circuit and discharge all capacitors.
2.
Rotate the function dial to mA/A .
3.
Press SELECT to select DC or AC. appears for AC current measurement.
4.

Note:
• The +V.
Ω .mA jack is is fuse-protected. If the meter cannot measure in 40/400mA ranges, check and replace the fuse.
• If the current’s polarity is negative, – appears before the value.
12
Measuring Resistance
1.
Disconnect power from the circuit and discharge all capacitors.
2.
Rotate the function dial to Ω .
3.
Repeatedly press SELECT to select Ω , K Ω , or M Ω .
4.
Connect the black test lead to one component lead.
5.
Connect the red test lead to the other component lead, or remove one component lead from its circuit and touch the test leads across the component.
n
Note :
• If no resistance is connected across the test leads (meaning resistance is infinite), or the value under testing exceeds the range you set, O.F
appears. This is normal.
• If you are measuring resistance of about 1M Ω or more, the display might take a few seconds to stabilize. This is normal.
13
Checking Continuity
You can check for shorted or open electrical circuits.
1.
Disconnect power from the circuit and discharge all capacitors.
2.
Rotate the function dial to Ω .
3.
Repeatedly press SELECT until appears.
4.
Connect the black test lead to one end of the circuit and the red lead to the other end.
• Open appears if the circuit resistance is greater than about 50 ±10 ohms (meaning the circuit is not shorted).
• Shrt appears and the buzzer sounds if the circuit resistance is less than about 50 ±10 ohms (meaning the circuit has low ohmage or is shorted).
Checking Diodes
You can check diodes, transistors, and other semiconductors for opens, shorts, and normal operation. You can also determine the forward voltage and polarity for diodes and check diode polarity when positive (+) and negative (–) sides are not marked.
1.
Disconnect power from the circuit and discharge all capacitors.
2.
Rotate the function dial to Ω .
14
3.
Press SELECT until appears.
4.
Connect the black test lead to the cathode or a component pin.
5.
Connect the red test lead to the anode or the other component pin, or remove one of the leads of the component from its circuit and touch the test leads across the component. Then note the first reading.
6.
Reverse the test leads and note the second reading.
• If one reading shows a value and the other is overrange ( .OF
appears), the device is good.
• If OF appears during both readings, the device is open.
• If both values are very small or zero, the device is shorted.
n
Note:
• The values for most semiconductors may vary depending on the temperature.
• The values that appear during a diode check show the actual forward voltage (max.
3.0V). If the voltage exceeds 3.0V, O.F
appears. This means the diode check cannot be made using this meter.
• Check diode polarity: Connect the test leads to the two ends of the diode. Measure and note the voltage. Then, reverse the test leads. The side of the diode where the meter shows a higher voltage using the red test lead is the anode (+) side. The side of the diode where the meter shows OF using the red test lead is the cathode (–) side.
15
Checking Batteries
The meter can accurately check the following batteries under designated load conditions:
• 1.5V C
• 1.5V D
• 1.5V AA
• 1.5V AAA
• 9V batteries.
1.
Rotate the function dial to your desired setting.
2.
Connect the black test lead to the battery’s negative (–) terminal
3.
Connect the red test lead to the battery’s positive (+) terminal.
• If you connect the test leads in reverse polarity, – appears on the left side of the display.
Use this table to determine the battery’s charge.
