4. Instruction on operating panel
4-1. Dada hold button（D.HOLD）
When press this key, the LCD screen will display the "HOLD"
symbol and the last time
Reading, Until you press this key or the function knob is
converted, the symbol disappears,and resume reading.
The key has a backlight function, press this key for more than 3
seconds, then turn on the backlight; Press this button for more than
3 seconds, then the backlight is off.
4-2. Select keys（SELECT）
Press "SELECT" key to turn on, the APO symbol on the display
disappears, the auto power off function is cancelled. If toggle the
knob to turn on normally, then it has auto power off function, it
will automatic shutdown in 15 minutes without any
operation.
When the function knob in the range
, press this key to choose required measurement
function.
When the knob is in C / Fahrenheit range function by
pressing this button can be C / Fahrenheit Conversion.
In AC / DC mV range, press the select key can switch to
mV and AC mV
4-3. HZ/DUTY KEY
Press this key to seclect the frequency or duty cycle
measurement
4-4. RANGE CONVERSION KEY（RANGE
）
AC / DC voltage, AC current, resistance and other
functions can be selected through the button by manual
or automatic range. Automatic range press this key on
the LCD screen after AUTO disappear, switch to manual
range at this time, press the button not more than 3
seconds to change the range;
If press the key more than 3 seconds , then it goes to the
automatic range.
5. Operating Instruction:
5-1.AC/DC VOLTAGE
a. Set the function switch to DCV V
—
or ACV V ～
position.
b. Inset the red test probe into the VΩjack，black one to
the COM jack.
c. Connect the test leads to the circuit which you want to
test, and read out the value display on the LCD.
Read the result and when you test DCV, you can see the
polarity of the red test probe at the same time.
5-2.RESISTANCE
a. Set the switch to range ， and press
“SELECT”to choose Ω mode.
b. Set the red test probe to VΩjack，and black one to the
COM jack。
c. Connect the test leads to the circuit which is ready to
be test or the two sides of the resistance.
Notice
When test the resistance over 2M Ω ， this meter needs
few seconds to keep stable. This is very normal when
test a high resistance.
When it is not connected or it is under a open circuit,
“OL” will display.
When you are testing the resistance on line, do please
make sure that the power of the circuit is off and the
capacitance have been already release completely.
5-3.ACA（A～）
Set the switch to A~ range, and put the wire vertical in
the centre of the clamp, at this moment the value show
on the LCD is the ACA value.
5-4.DIODE AND CONTINUITY TEST ( BUZZER)
a. Input the red test probe into V Ω jack， and black one
into COM jack.
b. Set the switch to range ， and press
“SELECT” to choose diode or buzzer mode。
c. During the buzzer test, if the resistance of the circuit
which you want to test is less than 50 Ω ,the buzzer
rings.
d. Under the diode test mode, connect the test leads to
the positive and negative poles of the diode.LCD will
display the value of the positive onset voltage.
5-5.TEMPERATURE
a. Set the switch to ℃/℉ position.
b. Connect the K type thermocouple to V Ω jack and
COM jack, pay attention to the polarity when testing.
c. Put measuring jack on the surface or inner of the
measured object. It shows temperature value.
Notes:
1) After insert temperature probe into device jack,
temperatures will display automatically
2) When temperature probe do not connect with device
jack, it shows temperature environment.
5-6. HZ/Duty Measuring.
a. Insert the red test probe into the VΩ jack and black
test probe into the COM jack.
b. Set the function switch in the HZ position, select the
measuring function, connect the test probe onto the
both ends of the being tested circuits.
5-7. Capacitance Measuring
a. Insert the red test probe into the VΩ jack and black
test probe into the COM jack.
b. Set the function switch in the position, press
“select” button to choose capacitance measuring function.
(Note: Polarity of red test probe shows “+”)
c. Connect test probe onto both ends of the capacitance
to be tested and confirm if the polarity is correct. (Note:
Before measuring, capacitance should be completely
discharged. When measuring large bulk capacitance, it
needs about 10 seconds to read stable data.)
6. Battery Replacement:
LCD display , you need to replace AAA 1.5V
battery promptly.
7. Notes: Do not input 250V DC or RMS AC under the
background of / Temperature ℃/℉ / Frequency
to prevent it from destroying.
