Preparation and Caution Before Use

•Inspect the digital multimeter for damage to the case. Do not use if cracked, distorted, excessively dirty or any abnormal condition exists.

•Inspect the test leads for damage. Check for cracked insulation, broken or damaged probes, loose or bent probe pins. Do not use if any abnormal condition exists.

•Set the Function/Range Selector Switch to the proper range BEFORE taking measurements. If the range/function must be switched during a test, ALWAYS remove the test leads from the circuit being measured before switching settings.

•To avoid possible electric shock, instrument damage, and/or equipment damage when taking voltage or current measurements, DO NOT exceed the maximum value of the selected range.

•If the unit is used near high noise Radio Frequency (RF) generating equipment (spark plug wires, ignition coils or alternator), the display may become unstable or indicate large errors. If you obtain erratic readings during use, isolate the Multimeter as far away as possible from these components.

TESTING PROCEDURES

A. AC/DC VOLTAGE MEASUREMENT

WARNING

To avoid possible electric shock, instrument damage and/or equipment damage, DO NOT attempt to measure voltages ABOVE 500V AC/DC or take measurements if the voltage is unknown. 500V AC/DC between the COM and V jacks is the maximum voltage that this instrument is designed to measure. The "COM" terminal potential should not exceed 300V AC/DC measured to ground.

6

E

1.Plug the BLACK test lead into "COM" jack of the multimeter; plug the RED test lead into the "V" jack.

2.Set the meter’s Function/Range Selector Switch to the appropriate ACV or DCV position as desired (see Controls and Indicators, Items 1 and 13).

3.Place the RED test lead onto the positive (+) side of the item being tested and the BLACK test lead onto the negative (-) (across the source/load) side of the item. BE CAREFUL not to touch any energized conductors with any part of your body.

4.Read the results on the display.

B. RESISTANCE MEASUREMENT Ω (OHMS)

WARNING

Resistance measurements must be made on "de-ener- gized" (dead) circuits ONLY. Impressing a voltage across the multimeter's terminals while set to any resistance range may result in electric shock, instrument damage and/or damage to equipment under test. MAKE SURE equipment is completely de-energized before taking any resistance measurements.

1.Plug the RED test lead into the "Ω" jack of the multimeter; plug the BLACK test lead into the "COM" jack.

2.Set the meter’s Function/Range Selector Switch to the OHM "Ω" range function (see Controls and Indicators, Item 3).

NOTE: To obtain accurate readings, disconnect at least one side of the item under test from the circuit or circuit board before measuring resistance.

3.Place the RED test lead onto one side of the item being tested and the BLACK test lead onto the other side of the item. (Polarity does not matter when checking resistance).

4.Read the results on the display.

C. DIODE TEST

WARNING

To avoid electrical shock and/or damage to the multimeter, ensure the power is removed from the circuit before any DIODE testing procedure is conducted. Test diodes on deenergized (dead) circuits only, never on live circuits.

7

E

NOTE: A diode is a semiconductor device that lets current flow in one direction only. If the diode to be tested is part of a circuit (with other electronic components), you must isolate it from the other components by disconnecting at least one side of it from the circuit before testing. A good diode will show a low voltage drop across its junction (0.5-0.8 volts for a silicon diode or about 0.3V for a germanium diode) when the leads are connected in one polarity and a very high resistance (or open circuit) when the leads are reversed (connected in the opposite polarity).

1.Plug the RED test lead into the jack of the multimeter; plug the BLACK test lead into the "COM" jack.

2.Set the meter’s Function/Range Selector Switch to the position (see Controls and Indicators, Item 4).

3.Place the RED test lead onto one side of the diode being tested and the BLACK test lead onto the other side.

4.Read the results on the display.

5.Reverse the test leads and again read the results on the display. Compare the two readings. One reading should indicate a voltage drop value; the other reading should indicate an overrange (1) condition. See note above.

D. CONTINUITY TEST

WARNING

To avoid electric shock, shut off the power to the test article before testing it for continuity.

1.Plug the RED test lead into the jack of the multimeter; plug the BLACK test lead into the "COM" jack.

2.Set the meter’s Function/Range Selector Switch to the position (see Controls and Indicators, Item 5).

3.Place the RED Test Lead to one end of the wire or device being tested for continuity and the BLACK Test Lead to the opposite end.

4.Listen to the sound of the beeper and confirm the results by reading the display.

NOTE: The beeper will sound only if the continuity of the item under test (resistance between the two test leads) measures less than approximately 50 ohms.

E. DC CURRENT MEASUREMENT (AMPS)

WARNING

To prevent electrical shock when performing current measurements, follow all steps as indicated below DO NOT skip any steps or take any short cuts.

The DC10A range is not fused. To avoid current hazard and/or damage to the tester, DO NOT try to take measurements on circuits that have more than 10 amps. DO NOT take more than 15 seconds to take the reading. A waiting period of AT LEAST 15 MINUTES is necessary between every 15 second testing period.

1.Plug the RED test lead into the "mA" or the "DC10A" jack of the multimeter, as applicable; plug the BLACK test lead to the "COM" jack.

2.Set the meter's Function/Range Selector Switch to the appropriate Amps range position as desired (see Controls and Indicators, Items 9 and 10).

•To measure from 0 to 200mA, set the Selector Switch to the desired "DCmA" position.

•To measure from 200mA to 10 Amps DC, set the Selector Switch to the "DC10A" position.

3.Disconnect the battery, or shut off the power to the circuit being tested.

NOTE: To measure current on a particular circuit, you must open up the circuit and connect the test leads in series with the circuit before a reading can be obtained.

4.Disconnect one end of the wire or device, from the circuit where current will be measured.

5.Place the RED test lead on the disconnected wire and place the BLACK test lead at the location from which the wire was disconnected (series connection).

6.Reconnect the battery, or apply power to the circuit being tested.

7.Read the results on the display.

CAUTION: After the test is completed, shut the power off to the circuit before removing the test leads and before reconnecting any disconnected wires or devices.

NOTE: If the reading obtained is a negative number, reverse the test leads.
