Step 2: The Update He inserted the flash drive, navigated the menu to System → Firmware Update, and selected the file. The scope warned that power loss during update could brick the device. Jun hooked the bench UPS to the wall outlet and confirmed battery health on the UPS display — good. He tapped “Start.”
: Inject a clean 50 MHz sine wave into Channel 1. Dial your horizontal timebase down to 2ns/div . If your firmware update is working correctly, the waveform's full single-cycle period will stretch across precisely 10 full horizontal grid divisions , verifying an exact 20-nanosecond validation. 3. Expanded Sensor Framework Check
Here is the process.
Once the progress bar reaches 100%, the software will report a successful transfer. The HDS2102S will typically reboot automatically. If it stays on a black screen for more than two minutes after a reported successful flash, manually cycle the power button. How to Verify the Update Success: Press the button on the physical keypad. Select System Info using the arrow keys.

Step 1: Preparation Jun backed up the scope’s screen captures, saved the configuration file, and removed the BNC leads from sensitive DUTs. He printed the update notes and checked the scope’s current version: 1.02. The update file on his flash drive was labeled HDS2102S_v1.04.bin, with a checksum published on the vendor page. He confirmed the MD5 hash matched. Verification first; assumptions later. owon hds2102s firmware update verified
Ensure your HDS2102S has at least 50% battery or is plugged into a stable power source.
Requires manual installation of USB drivers and putting the device into bootloader mode by cycling power while connected to the PC. OWON HDS 200 Handheld Oscilloscope w/ builtin DMM/AWG

⚠️ : If your device currently reads V4.1.0 , you can safely upgrade across incremental patches in that tier (e.g., up to V4.7.1). You cannot cross-flash a V4.X device with V1.5.1 or V2.0.4 firmware. Doing so mismatching the boot sector structures, immediately causing a catastrophic device failure. Step-by-Step Installation Guide

The main version number of your scope is usually indicated by the letter "V" followed by numbers (e.g., V1.5.1, V2.0.4, V3.x.x, V4.x.x). According to official OWON statements and community testing on the EEVblog Forum : Jun hooked the bench UPS to the wall
Early firmware configurations on the HDS2102S contained a notable scale compression bug at extreme horizontal speeds. Specifically, at the sweep setting, graticules failed to expand linearly.
