Digital Multimeter
Operation Manual

We thank you very much for your purchasing our products .They are most reliable, high-precision instrumenh.
designed by our excellent technology .Before you use your new instrument, please read this OPERATION MANUAL
completely and familiarize you selfthoroughly with all function and connections with proper use and care your digital
multimeter will give you years
of satisfactory service.
Safety rules
•Use the meter only as specified in this manual.
•Never measure voltage while the test leads are at the current test state.
•Do not use the meter
if it looks damaged.
•Inspect the leads for damaged insulation or exposed metal, check test lead continuity, replace damaged leads.
•Disconnect the power and discharge all high-voltage capacitors before testing in resistance, continuity, and diode
function.
•Be Cautions when working above
DC 60V or AC 42V ,such voltages may cause ashock hazard.
•When making measurement, keep your fingers behind the guards plant on the probes.
•Select the proper function and range for measurement, to avoid damaging the meter, disconnect the test leads from
test points before change function.
• If the voltage of measuring frequency is too high the meter will into protection state the display can't indicate
measurement value.

Measurement range
Ameasurement range detennines the highest value the meter can measure ,Most meter functions have more than one
range. So being in the right measurement range is important. If the range is too low for the input, the meter displays
"OL" to indicate overload
.If the range too high •the meter will not display the most accurate measurement .Power on
the meter it
in auto range mode. Press RANGE the meter enters the manual range mode and "AUTO" turn off. Each
press
of RANGE increments the range. When the highest range is reached. the meter wraps to the lowest range. Turn
switch to any position the meter will exit manual range
mode. In the auto range mode. the meter selects the best
range for the input
detected. In the manual range mode. you can select the range .This allows you to override auto
range and lock the meter in aspecific
range.

"""' V " position.
2. Connect the black test lead to "COM" tenninal and the red test lead to" "* .", -If- V/ Q 1Hz" tenninal .
3. Touch the probes to the test points and reading the display ,at same time,you can press HzlDUTY bullon obtain the
signal frequency and duty
of voltage is in measured.

2. Connect the black test lead to " COM" tenninal and the red test lead to" "* . ." -If- VIQ 1Hz "terminal .
3. Touch the probes to the test points and read the display ,at same time,you can press HzlDUTY bUllon obtain the
signal frequency and duty
of voltage is in measured.
OC /AC Current measurement
L1'\ Warning
To avoid damage to the meter or injury if the fuse blows ,never attempt an in-circuit current measurement
where the open-circuit potential to
earth is greater than 6OOV. To avoid damage to the meter, check the meter's
fuses before proceeding.
Use the proper terminals, function, and range for your measurement. Never place
the probes in parallel with acircuit
or component when the leads are plugged into the current terminais •
I. Turn off power to the circuit. Discharge all high-voltage capacitors .

COM" terminal and the red test lead to" +I- .,,) -II- VI 0 1Hz "terminal .
3. Press HzJDUTY to select Hz or DUTY test mode .
4. Touch the probes to signal source and read
display.
Note: When the rotary switch at voltage or current measurement positions, press HzJDUTY can measure frequency or
duty cycle also.

The meter is powered by
R6l> or 1.5V AA battery two pieces •Replace battery if the low battery sign "~ "is
displayed .
(I) Set the rotary switch to " OFF " position.
(2) Loosen screws on battery cover. pull up and move the battery cover.
(3) Replace the defective battery .
(4) Reverse the procedure
