Early firmware versions (v1.0.3 – v1.1.2) suffered from a known "Vamp" (Voltage amplitude) error when measuring high-frequency square waves above 20 MHz. Users reported a 5-7% deviation. Updates post-v1.2.0 recalibrate the DSP coefficients.
You will need:
Steps:
If that doesn’t work: consult the official instructions included with the firmware package.
Switch to DMM mode. Measure a 9V battery. If the reading flickers or shows "OL" incorrectly, roll back to the previous firmware (see Part 7 below).

The Owon HDS2102S
is a handheld 3-in-1 test instrument featuring a 100MHz oscilloscope, 20,000-count multimeter, and a 25MHz waveform generator. Updating its firmware is a sensitive process because the device has undergone multiple hardware revisions, and flashing incompatible firmware can brick the display.
Below is a detailed guide on the firmware update process and current manufacturer recommendations. ⚠️ Critical Pre-Update Warnings
Version Compatibility: Firmware is strictly tied to the hardware version (e.g., V1.x.x, V3.x.x, V4.x.x). You cannot update a V1.x unit to V4.x or V5.x.
Manufacturer Advice: Owon has explicitly stated to some users that they should not upgrade firmware if the device is functioning normally, as official updates are often not hosted publicly to prevent bricking.
Hardware Check: To find your current version, press System -> System -> Page 2 -> About. Update Procedure
If you have obtained the correct .upp file from Owon Support or an official representative, follow these steps: Prepare the Device: Power on the . Enable Mass Storage (MSC): Press System.

Verify: Turn the device on and re-check the version in the System menu to confirm the change. Firmware History & Fixes
V1.5.1: This version was notable for fixing a significant display error in the 2ns/div horizontal range where timing graticules were incorrectly spaced.
Recent Versions: Newer hardware shipments have been seen with V4.x and V5.x firmware, which often include better unit support (like Amperes for clamp meters). Important Note on Rebadges: Devices like the Victor 2102S
are nearly identical but may use different internal IDs, making Owon-branded firmware potentially incompatible.
Updating the firmware on your Owon HDS2102S handheld oscilloscope is a critical maintenance step to resolve display discrepancies, fix bugs, and occasionally unlock new measurement features. Why Update Your Owon HDS2102S Firmware?
Accuracy Fixes: Earlier versions (e.g., v1.50) suffered from a horizontal spacing bug at the setting, where signal periods were displayed incorrectly.
New Features: Recent firmware transitions (e.g., from v4.1.0 to v4.7.1) have introduced RMS measurements and support for ampere units for clamp meter users.
System Stability: Updates often address 2-channel trigger bugs and translation errors. How to Update Owon HDS2102S Firmware
The update process for the HDS200 series typically involves using the device in "Mass Storage Class" (MSC) mode.
Check Current Version: Turn on your device, press the System button, and navigate to the System menu to view your current version.
Download Firmware: Visit the official Owon Download Center. You may need to enter your current version number to see compatible updates.
Note: If no update appears on the site, contact info@owon.com.cn with your serial number and current version to request the latest file.
Prepare the Device: Connect your HDS2102S to a PC via a USB-C to USB-A cable.

is a delicate process because OWON generally does not publish public firmware links for this specific model . Firmware is typically tied to specific hardware/serial number revisions, and using the wrong "piece" (firmware file) can brick the device . Critical Warning
Official advice from OWON support is to not upgrade unless you are experiencing a specific bug, as there is no universal "latest" version for the
on their website . If you proceed, ensure the firmware you use matches your hardware revision exactly . Firmware Update Steps
If you have obtained the correct .upp file from OWON Support or an authorized source, follow these steps : Prepare the Device: Turn on the and navigate to System > System > (Next Page) > Upgrade.
Connect to PC: Connect the oscilloscope to your computer using a USB-C cable.
Enable MSC Mode: In the System menu, select USB and set it to MSC (Mass Storage Class). The scope will appear as a removable disk on your computer.
Transfer the File: Copy the firmware file (typically named Scope.upp) to the root directory of the removable disk.
Reboot and Flash: Safely eject the device, turn the scope off, and then turn it back on. The device will automatically detect the file, perform the upgrade, and shut down once finished.
Verify: Turn the device on and check the System menu to confirm the version number has updated. Common Firmware Versions & Fixes
Version 1.5.1: Known to fix a specific display discrepancy where graticules were incorrectly spaced at the 2ns/div time base .
Version 2.0.4: A newer update reported by some users, though specific changelogs are often not provided by the manufacturer . Troubleshooting & Support Official Downloads: You can check the OWON Download Center for any newly released software or manuals, though specific firmware is rarely listed there.
