drop will be displayed
The built-in buzzer will sound if the Open circuit voltage: about 0.5V
resistance is less than about 30Ω.
Overload Protection: 250V DC/AC rms
For continuity test: When the resistance is between 30Ω and 100Ω, the buzzer may sound
or may not sound. When the resistance is more than 100Ω, the buzzer won’t sound.

Measuring Voltage
1) Connect the BLACK test lead to the “COM” jack and the RED to the “INPUT” jack.
2) Set the function switch to V or V range.
Select auto range or manual range with the “RANGE” button.
3) In manual range, if the voltage magnitude to be measured is unknown
beforehand, select the highest range.
4) Connect the test leads across the source or load to be measured.
5) Read LCD display. The polarity of the RED lead connection will be indicated
when making a DC measurement.
NOTE:
a. In small range, the meter may display an unstable reading when the test leads
have not been connected to the load to be measured. It is normal and will not
affect the measurements.
b. In manual range mode, when the meter shows the over range symbol “OL”, a
higher range must to be selected.
c. To avoid damage to the meter, don’t measure a voltage which exceeds 600Vdc
(for DC voltage measurement) or 600Vac (for AC voltage measurement).
Measuring Current
1) Connect the BLACK test lead to the “COM” jack.
2) Set the range switch to desired µA or mA range. If the current magnitude to be
measured is not known beforehand, set the ranges switch to the highest range
position and then reduce it range by range until satisfactory resolution is obtained.
3) Select DC current measurement or AC current measurement with the “SELECT” Button.
4) Select auto range or manual range with the “RANGE” button. In manual range, if the
current magnitude to be measured is not known beforehand, select the highest range.
5) Connect test leads in series with the circuit to be measured.
6) Read the reading on the display. For DC current measurement, the polarity of the red
test lead connection will be indicated as well.
NOTE: When the display shows the over range symbol “OL”, a higher range must be selected.

Measure Resistance
1) Connect the BLACK test lead to the “COM” jack and the RED to the “INPUT” jack
(Note: The polarity of the red test lead is positive “+”).
2) Set the range switch to Ω range
3) Select auto range or manual range with the “RANGE” button. In manual range, if
the current magnitude to be measured is not known beforehand, select the
highest range.
4) Connect the test leads across the load to be measured.
5) Read the reading on the display.
NOTE:
a. For resistance measurements >1MΩ, the meter may take a few seconds to
stabilize reading. This is normal for high-resistance measurement.
b. When the input is not connected, i.e. at open circuit, the symbol “OL” will be
displayed as an over range indicator.
c.
Before measuring in-circuit resistance, be sure that the circuit under test has all
power removed and all capacitors are fully discharged.
Continuity Test
1) Connect the BLACK test lead to the “COM” jack and the RED to the “INPUT” jack
(Note: The polarity of the red test lead is positive “+”).
2) Set the range switch to range
3) Press the “SELECT” Button to select continuity measurement mode, and the
symbol “ ” will appear as an indicator.
4) Connect the test leads across the load to be measured.
5) If the circuit resistance is lower than about 30Ω, the built-in buzzer will sound.
Diode Test
1) Connect the BLACK test lead to the “COM” jack and the RED to the “INPUT” jack
(Note: The polarity of the red test lead is positive “+”).
2) Set the range switch to range
3) Press the “SELECT” Button to select continuity measurement mode, and the
symbol “ ” will appear as an indicator.
4) Connect the red test lead to the anode of the diode to be tested and the black
test lead to the cathode.
5) The meter will show the approximate forward voltage of the diode. If the
connections are reversed, “OL” will be shown on the display.
Battery Test
1) Red lead to ”VΩmA”, Black lead to ”COM”
2) RANGE switch to desired ”BATT” position.
3) Connect red test lead to the battery’s negative.
4) The display will read the battery’s voltage.
Auto Power Off
If you don’t operate the meter for about 15 minutes, it will turn off automatically. To turn
on it again, just rotate the range switch or press a button.
If you press the “SELECT” button and turns on meter, the automatic power-off function
will be disabled.
Battery Replacement
If the sign “ ” appear on the display, it indicates battery should be replaced. Remove
screws and open the back case, replace the exhausted battery with new batteries (Size
AAA, 1.5V x2 or equivalent).
Fuse Replacement
Fuse rarely needs replacement and is blown almost always as a result of operator’s
error. To replace the fuses, open the battery cover; replace the damaged fuse with a
new fuse of the specified ratings.
Reinstall the battery cover and lock this cover.
Disposal
If you intend to dispose of this article, then please keep in mind that many of its
components consist of valuable materials, which can be recycled. Please do not dispose
it in the garbage, but check with your local council for recycling facilities in your area.
