PREPARATION

Installing the battery

Your meter requires 3 AA batteries (not included).

• To avoid electrical shock, disconnect both of the meter’s test leads from any equipment before
you install or remove the meter’s battery.

• Do not operate your meter until the battery is properly installed and the battery compartment
cover is in place and secured.

Caution: Use only a fresh battery of the required size and recommended type.

1. Set the selector to OFF.

2. Use a Phillips screwdriver to loosen the screws in the battery compartment cover, then lift off
the cover.

3. Place the battery in the compartment as indicated by the polarity symbols (+ and -) marked
inside.

4. Replace the cover and secure it with the screws.

When appears on the display, the display dims, or the meter does not seem to measure
accurately, replace the battery. If the battery power is extremely low, does not display.

Warning: Dispose of old batteries promptly and properly. Do not bury or burn them.

Caution: Always remove an old or weak battery. Batteries can leak chemicals that can destroy

electronic parts. If you are not going to use the meter for a few weeks, remove the battery.

USING THE METER

Caution: Do not try to measure voltage greater than 1000V DC/ 750V RMS AC.

To use the meter, open the meter’s case by pulling the tabs on the case in
opposite directions. Then unwind the test leads from inside the cover.

Caution: The test leads are permanently attached to the meter. Do not try to remove them.

Rotate the selector to the function you want to use. Then connect the test leads to the circuit you
want to measure. See the unit of measure on the front of the meter to distinguish the range. For
example, DC V includes five ranges; 400 mV, 4V, 40, 400 and 1000.

Caution: If OL appears when you are measuring voltage, the value you are measuring exceeds
the meter’s maximum range. Immediately disconnect the probes from the circuit or your meter
might be damaged. Also, note the position of the decimal.

When you finish using the meter:

1. Set the selector to OFF .

2. Put in carrying case.

3. Tuck the test leads inside the carrying case and close the cover.

Making measurements

Measuring DC/ AC Voltage

Warning: The maximum input limit for voltage measurement is 1000V DC and 750V AC (RMS). To
avoid electrical shock and damage to the meter, never try to measure a DC voltage above 1000
volts or an AC voltage above 750 volts RMS.

Follow these steps to measure DC or AC voltage:

1. Set the selector to DC V to measure DC voltage or set AC V to measure AC voltage.

2. Connect the test leads to the circuit you want to test.

3. If you cannot determine the correct position, set the range switch to the highest range for the
type of voltage (AC or DC) you are measuring, then reduce it as necessary until the correct

Page 6

Digital Multimeter With Voice Readout

2218202

voltage appears.

4. If you want the meter to announce the test result, press the switch on the red test lead
for less than 1.5 seconds. If you want the meter to be alluminated press the switch on the red
test lead for more than 1.5 seconds, and the meter will be lit for 30 seconds.

Measuring AC Voltage Riding on a DC Source Bias

To measure an AC voltage superimposed on a DC voltage source bias, you must first measure the
DC and AC voltages separately, then compute the peak voltage using this formula:

AC voltage
Peak voltage

= DC voltage +.707

Warning: To avoid injury to yourself or damage to your meter, never try to measure an AC voltage
that is riding on a DC source bias where the peak voltage exceeds 500 V with respect to earth
ground.

Caution: Never try to measure any voltage more than 30V AC on a DC source bias.
Follow these steps to measure AC voltage:

1. Set the selector to DC V.

2. Connect the test leads to the circuit you want to test. The display shows the DC voltage.

3. Disconnect the test leads from the circuit.

4. Set the selector to AC V.

5. Connect the meter’s test leads again to the same circuit you tested in Step 2. The display
shows the AC voltage.

6. To compute the peak voltage, refer to the formula seen above.

Measuring resistance

The resistance measuring circuit in your meter compares the voltage gained through a known
internal resistance with the voltage developed across an unknown resistance.

Warning: Be sure the circuit under testing has all power removed and any associated capacitors
are fully discharged before you make a resistance measurement.

1. Set the selector to OHM/DIODE/CONTINUE.

Caution: Your meter has a circuit to protect the resistance range from over-voltage. However, to
prevent accidentally exceeding the protection circuit’s rating and to ensure a correct
measurement, never connect the test leads to a source of voltage while the selector is set to
OHM/DIODE/CONTINUE.

Note:

1. If there is no resistance connected across the test leads or the measured value exceeds the
range you set, OL appears when you set the selector to OHM. This is normal.

2. Connect the test leads across the circuit you want to measure. Or, remove one of the
component’s leads you want to measure from its circuit and connect the test leads across the
component. The meter displays the reading in the chosen range.

3. If you want the meter to announce the test result, press the switch on the red test lead
for less than 1.5 seconds. If you want the meter to be alluminated, press the switch on the red
test lead for more than 1.5 seconds, and the meter will be lit for 30 seconds.

Checking diodes

This measurement lets you check diodes, transistors, and other semiconductors for opens, shorts,
and normal operation. It also lets you determine the forward voltage for diodes. (This is handy
when you need to match a diode).

Caution: Do not connect the test leads to a source of voltage when you set the selector to Diode.
This could damage the meter or circuit being tested.

Page 7

1. Position the selector switch on the OHM/DIODE/CONTINUE and press the “FUNCTION” key.
to change the meter to the diode function.

2. Remove power from the circuit under test.

3. Connect the test leads across the circuit you want to measure, or remove one of the
component’s leads you want to measure from its circuit and connect the test leads across the
component. Then note the first reading.

4. Reverse the test leads and note the second reading.

In a circuit, a good diode should till forward-bias reading of 0.5V to 0.8V; however, the reverse­bias reading can vary depending on the resistance of other pathways between the probe tips.

Note:

1. The values that appear during the diode check show the actual forward voltage (max. 1.5V).

2. If you want the meter to announce the test result, press the switch on the red test lead
for less than 1.5 seconds. If you want the meter to be alluminated, press the switch on the red
test lead for more than 1.5 seconds, and the meter will be lit for 30 seconds.

Continuity Sound Test

Position the selector switch on the OHM/DIODE/CONTINUE and press the “FUNCTION “key to
change the meter to the continuity function.
Audible beep when R<35 ohm.

Cap Test

Position the selector switch on the “CAP” function. Press the “REL” key to make the meter “zero”.

Automatic range selection: Read the measured value. The capacitance should be discharged
before the test. Hold, if necessary, by pressing the “HOLD” key.
If you want the meter to announce the test result, press the switch on the red test lead for less
than 1.5 seconds. If you want the meter to be alluminated, press the switch on the red test lead for
more than 1.5 seconds, and the meter will be lit for 30 seconds.

Frequency Measurement

Position the selector switch on the “Hz” function.

Automatic range selection: Read the measured value. Hold, if necessary, by pressing the
“HOLD” key.

If you want the meter to announce the test result, press the switch on the red test
lead for less than 1.5 seconds. If you want the meter to be alluminated, press the switch on the
red test lead for more than 1.5 seconds, and the meter will be lit for 30 seconds.

Note: Because of high sensitivity in this function, the meter will catch a signal and will display the
number with the test-leads open.
