(2) Check the probes connected to the channels firmly

(3) Check the probes connected with the object being tested.

(4) Check the circuit generates signal on the test point

(5) Repeat the acquisition

3. The measurement result is 10 times higher or lower than the value

expected.

Check if the probe attenuation is the same as the channel attenuation.

4. if the oscilloscope does not get a stable waveform display, please check

according to the following steps:

(1) Check the Trigger Source and notice if it is set to the channel you use

(2) Check the Trigger Type. You should use “Edge” for normal signals, and use

“Video” for VIDEO signals.

(3) Switch the coupling into HF Rejection or LF Rejection in order to filter the noise
