3） Connect the test leads to the positive and negative poles of the diode to be tested
respectively.
4） The meter displays the forward bias value of the diode to be tested. If the polarity of
the test lead is reversed, the meter will display “O.L”.
4.12 Beep Continuity Test
1） Turn the rotary switch to the  position and press “FUNC” to choose .
2） Connect the test leads in black and in red to COM input socket and V/ input socket
respectively.
3） Use another two ends of the test lead to measure the resistance of the circuit to be
measured. If the measured distance is less than 30, the beeper will sound
continuously, and the LED will be on.
4.13 Capacitance Measurement
The measuring ranges for the capacitance of this meter are 6nF/60nF/600nF/6μF
/60μF/600μF/6mF/100mF.
Measurement of capacitance:
1） Turn the rotary switch to the  position, press “FUNC” to choose .
2） Connect the test leads to COM input socket and V/ input socket respectively.
3） Use another two ends of the test lead to measure the capacitance of the capacitor to
be measured, and capture the measured value on LCD screen.
Note:
 The measurement of a large capacitance requires a given period of stabilization of
reading.
 To avoid damage to the meter, the measurement of a capacitor with polarities
requires much attention to its polarity.
4.14 Temperature Measurement
1） Turn the rotary switch to the ℃/℉, press the “FUNC” to choose ℃ or ℉.
2） Insert the red plug of the thermocouple into the end of V/℃, and insert the black
plug of the thermocouple into COM socket.
3） Place the temperature probe on the object being measured, and temperature the
measured value on LCD screen.
