1. Product Introduction
The DSO-153 is a highly practical and cost-effective handheld oscilloscope launched by FNIRSI, targeting the maintenance, development, and education industries. This oscilloscope features a real-time sampling rate of 5MS/s, 1MHz bandwidth, and a complete triggering function (single, normal, auto). It can be used for both periodic analog signals and non-periodic digital signals, and can measure voltages up to ±400V. With an efficient one-click AUTO function, it displays the measured waveform without complicated adjustments. Additionally, it includes a 10KHz signal generator. The device is equipped with a 2.8-inch 320 * 240 resolution HD LCD screen and a built-in 1000mAh high-quality lithium battery, providing approximately 4 hours of use when fully charged.

7. Points for Attention
- After receiving the device, please use it when fully charged.
- When using the oscilloscope, pay attention to the selection of the gear (range/sensitivity), and ensure it is 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 while the device is charging.
- When calibrating, it is necessary to unplug the BNC probe or short circuit the positive and negative terminals of the probe.
- USB firmware upgrades only support WIN10 and above. It is prohibited to drag files other than the released firmware, as this may cause irreparable consequences.
- Please charge using the voltage within the specifications provided in the instruction manual.
