Trigger mode indicator icon, Auto means automatic trigger, Single means single trigger, Normal means normal trigger.
Baseline indicator icon, this icon indicates the current position is OV voltage.
Vertical sensitivity, which means the voltage represented by a large grid in the vertical direction.
1X/10X mode indicator icon, this must be consistent with the 1X/10X switch setting on the probe handle if the probe is in 1X mode, then the oscilloscope should also be set to 1X mode, 1X measures ±40V voltage, 10X measures ±400V voltage.
Horizontal time base, indicating the length of time represented by a large grid in the horizontal direction.
Input coupling indicator icon, AC means AC coupling and DC means DC coupling.
Pause running indicator icon, RUN means running, STOP means pause.
Trigger voltage indicator icon
Trigger edge indicator icon

Firmware upgrade

The device currently uses a USB analog U disk for ﬁrmware upgrade, and the upgrade steps are as follows:

Press the “OK” button after pressing the power button so that to enter the U disk upgrade mode.
Use the Type-C cable to connect the Type-C port on the board to the computer. At this time, the computer will pop up a U disk named “DSO BOOT”.
Pull the ﬁrmware into the U disk, and the ﬁrmware upgrade will complete.

Note
The ﬁrmware upgrade is only supported on the computer Windows 10 system.

Precautions

After receiving the device, please use it after fully charged.
When using the oscilloscope, pay attention to the selection of the gear, the gear of the oscilloscope should be consistent with the gear of the probe.
When measuring high voltage, it is forbidden to touch any metal part of the oscilloscope to avoid the risk of electric shock.
Try not to perform a high-voltage test while charging.
When calibrating, need to unplug the BNC probe, or short the positive and negative poles of the probe.
The USB ﬁrmware upgrade only supports WIN10 or above, and it is forbidden to drag in ﬁles other than the released ﬁrmware, otherwise, it may cause unrecoverable consequences.
Please use the voltage within the speciﬁcation range of the manual for charging.
