Screen instructions
- 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.
