1.
If the oscilloscope does not start up at power on, please follow steps below:
⚫ Check the power cord to verify whether it has been connected properly and whether the power supply
is normal;
⚫ Check the power on/off buttons to ensure it has been pushed, and if you are using battery, check whether
the battery is in good condition;
⚫ Restart the oscilloscope after the checks above;
⚫ Contact Micsig if the problem persists, and we will provide service to you.
2.
If acquired waveforms do not display on the screen when the signal source is connected, please follow
the steps below:
⚫ Check whether the probe is connected correctly in the BNC socket;
⚫ Check whether the probe is connected correctly in the signal source;
⚫ Check whether the trigger type is correctly selected;
⚫ Check whether trigger conditions are set correctly
⚫ Check whether signal source is working properly;
⚫ Check whether the channel is turned on;
⚫ Check whether the vertical scale factor is set correctly;
⚫ Check whether the instrument is in single-sequence waiting state for trigger
⚫ Tap to resample signal.
3.
If the measured voltage amplitude is 10 times greater or smaller than the actual value:
⚫ Check whether the set attenuation factor of the channel is consistent with the attenuation factor of the
actually used probe.
4.
There is a waveform display, but cannot be stable:
⚫
Check the trigger source on the trigger type menu to ensure that it is consistent with the actually used
signal channel;
⚫ Check the trigger type: edge trigger is adopted for general signal, and video trigger mode for video
signal. Only the correct trigger mode is used, the waveform can be displayed stably;
⚫ Check signal source noise. Set the trigger coupling mode to be high-frequency hold-offor low-
frequency hold-offto filter out high frequency or low frequency noise interference
5.
A waveform is displayed but inconsistent with the input waveform:
