Product Introduction
DSO-153 is a highly practical and cost-effective handheld oscilloscope launched by our company, targeting the maintenance industry and development education industry. This oscilloscope has a real-time sampling rate of 5MS/s, 1MHz bandwidth, and complete triggering function (single, normal, auto). It can be used freely for both periodic analog signals and non periodic digital signals, and can measure up to ± 400V voltage with an efficient one click AUTO, which can display the measured waveform without complicated adjustments. In addition, it also comes with multiple functions signal generator (10KHz). Equipped with a 2.8-inch 320 * 240 resolution HD LCD screen and a built-in 1000mAh high-quality lithium battery, it can be used for about 4 hours when fully charged.

Screen Indication
- Vertical unit: represents the voltage represented by a large grid in the vertical direction
- Probe ratio: This must be consistent with the setting of the 1X/10X switch on the probe handle. If the probe is in 1X mode, then the oscilloscope should also be set to 1X mode, where 1X measures 40V voltage and 10X measures 400V voltage
- Horizontal time base, representing the length of time represented by a large grid in the horizontal direction
- Input coupling method indicator icon, AC represents AC coupling, DC represents DC coupling
- Trigger voltage indicator icon
- Trigger position indicator icon
- Baseline indicator icon, this icon indicates the current position as 0V voltage
- Run pause indicator icon, RUN represents run, STOP represents pause
- Trigger mode indicator icon, Auto represents automatic triggering, Single represents single triggering, Normal represents normal triggering
- Trigger edge indicator icon
- Signal generator on/off indicator icon

Firmware Update
- In the case of shutting down, press and hold the first and then press power button.
- Use a Type-C cable to connect the Type-C port on the board to the computer, and a USB drive named “IAP” will pop up on the computer.
- Pull the firmware into the USB drive, and if the firmware upgrade is completed, it will automatically jump to the APP.
Notice
- Firmware upgrade only supports use on computer Windows 10 and above systems.
- During the upgrade process, you need to keep pressing the power button until the file transfer is complete.
Points for Attention
- After receiving the device, please use it when fully charged.
- When using oscilloscope, pay attention to the selection of gear, and the gear of the oscilloscope should be consistent with the gear of the probe.
- When measuring high voltage, do not touch any metal parts of the oscilloscope to avoid the risk of electric shock.
- Try not to conduct a high-voltage test during charging.
- When calibrating, it is necessary to unplug the BNC probe or short circuit the positive and negative terminals of the probe.
- USB firmware upgrade only supports WIN10 and above. It is prohibited to drag files other than the released firmware, otherwise it may cause irreparable consequences.
- Please charge using the voltage within the specifications in the instruction manual.
