Prompt!
It’s neither able to use the waveform display nor the REL function in the frequency measuring!
In the function of frequency measuring, the width of the testing signal should be no less than 2Vp-p, and the
utmost input voltage should lower than 380V.
Resistance measuring
Warning!
To prevent electric shock, you should firstly cut off the electric power of the measurand ( take off the
batteries/ pull out the power wire), and discharge the capacitance of the electric power supplier.
1. Put the banana plug of the black P-wire into the cathode COM socket, and the red
one to the anode
socket.
2. Spin the function switch to select a proper range (200
Ω
~20M
Ω
) according to the
magnitude of the Resistance.
3. Cross connect the circuit or component with the test pen, it’s better to take off the
tested component for the measuring to make sure other part of the circuit won’t
affect the accuracy of the measuring result
4. Read the Resistance displayed on the screen, it may include the numerical value,
decimal point and cathode/anode determined.
