PS:
Don't trust any of the reviewes posted on Youtube about this device.

My post on Kerry Wong video was pushed last (I suppose due to "unlike" ?!...). It's OK.
I want to thanks to the person who unburied my post - is last on that video.
( Next target: let's see if Kerry is geting a firmware update. It's up to you what you do.)

Hot off the email, for HDS272S, board version 3.0 ONLY, here’s firmware version 5.6.3

Also check your serial numbers before committing to a potential brick. This is a legit firmware, but we can’t be your nanny 😁

[rn777]

In response to my requests, I also received this firmware today. v.5.6.3

Thanks. It's already been posted ^ but thanks

Yours was for V3 boards only and 1168.15 kB while rn777's was 634.82 kB.
They smell like the same firmware versions but for different HW builds.

Best someone compares them closely before buggering their scope.

Let's approach this from a proper perspective, running "sha1sum" on both, as I have here (feel free to replicate) - summary - the files are identical (unzip them first, then run "sha1sum" on each).

As supplied by Owon, mine was uncompressed, and clumsily named "Scope(1).upp"  so I renamed it, and zipped it using "0" ("store" level zipping, no compression)

Done, see photo attached.

In new firmware 5.6.3

1. Switching in resistance measurement mode is very slow.

2. Unlock capasitometer over than 2000mF

3. FIXED Osciloscope measured frequency is flawed / wrong when Acqu Mode is set to "Peak detect"

How to test:
(Use Mode to switch to activate oscilloscope).
In HOR menu check that Acqu Mode is set to "Sample".
In Measure menu activate Frequency for the channel that you are using.
Connect oscilloscope probe to calibration port.
Check the measured frequncy on display ( it should be 1KHz).
Use HOR menu and set Acqu Mode is set to "Peak detect".
Check the measured frequency on display (on my units 2.2 Khz instead of 1KHz).

4.FIXED In Trigger menu: The line that represents Trigger level is shown if Coupling option is set to "DC" but is NOT shown if Coupling option is set to "AC".

How to test:
Press Trig button.
Set Coupling to "DC".
User arrows to set a level.
(Note that trigger level is shown on display like a popup message and a line).
Set Coupling to "AC".
User arrows to set a level.
(Note that trigger level is shown on display the line that represents the level is not shown)

If you're interesting other function, need write message for support.
The more users write, the faster the questions will be resolved.

Nice 

To sum up:
a) Fixed.
b) Fixed.
c) Fixed.
d) Fixed (a "Counter" option have been added.)
e) Fixed.
f) Fixed.
g) Fixed.
h) Questionable
i) Fixed.

This is fun: I was writing this post when I got an email from Owon.
It seems that pushing them a bit worked ? I hate when you have to do that.

Edit: I have to check the upgrade file before posting.

[tly]

!!! WARNING - THIS FILE WASN"T HAVE BEEN TESTED!!!
You use the file on your own risk
If you need an update contact Owon first.

This update applies ONLY to:
- device: HDS272S (device with signal generator)
- SN : 2128xxx
- board version: V2.0
- old firmware version: 3.2.0

Upgrade steps:

First unzip the downloaded file then rename "Scope-V3.3.3_model-HDS272S_board-V2.0_SN-2128xxx.upp" file to "Scope.upp"

1. turn on the HDS scope, push "system" and then select F2 "system", to next page, select "upgrade"

2. connect PC with HDS scope by USB cable, push "system", in next page, select USB as "MSC", the removable disk will pop up.

3. copy the attached "Scope.upp" to removable disk such as H disk.

[ turn off your scope and then turn on again. The scope will upgrade and turn off after finish. ]

4. turn on your scope to check the version number changed in "system" menu，V3.3.3  .

This upgrade package is only applicable to HDS272S, version V3.*.* Upgradeable.

----------

To change language use:

I have a HDS272S with the following data:
FW: V3.1.0, SN: 2124XXX and board version: unknown (the about/system doesn't give me this info...)
Can I use this file for the update to the V3.3.3?

[rn777]

You need disassemble you're device, and you can see h/w version. Because there are several revisions (2.0, 2.1, 3.0).
You can see this information in this forum.

I have a HDS272S with the following data:
FW: V3.1.0, SN: 2124XXX and board version: unknown (the about/system doesn't give me this info...)

I would sugest you to wait until next Friday. It seems they are (manually) sending the mails with FW updates in batches.

------------------
Based on the info I gathered:
1. Owon sends the update based on serial number ( the first 4 digits of SN represents the batch or something like that; those 4 digits are marked on display side of board).
2. board version v2.0-2021-03-24 was used for devices with SN between 2118xxx and 2129xxx .
3. initial FW versions of these devices: v3.0.0, v3.1.0, v3.2.0
4. In the update mail is specified : "This upgrade package is only applicable to HDS272S, version V3.*.* Upgradeable."

We need more feedback from those who updated their devices - first 4 digits of SN and FW version used.

The FW file that I posted has following:
- MD5:  4265d84170607fc7827600e9d35d7319
- SHA1: b79c51348f1630828da1d61a36e247b82ca6f452

If you don't want to post the updated FW file that you received at least post the first 4 digits of SN, FW version received and MD5/SHA1 of file.

[saresigi]

It was probably not a good idea to post my data in the signature.
After I did a firmware update today and changed the firmware from 3.2.0 to 3.3.3 in my signature, the new firmware is now also in my old postings, although the old FW was still on it back then.
But this is only incidental.

After I received a "Scope.upp" from OWON, I tested the new FW and can confirm the results from "tly" (except for the point "h") I haven't tried that yet.

SHA1: b79c51348f1630828da1d61a36e247b82ca6f452

But I think I found a new bug (bug "k"). I skipped "j" because of the risk of confusion.

The scope has a built-in WOM (Write Once Memory ).
I saved all four files with an image using the Save function Type="Image".
I didn't manage to delete these four files or overwrite them with a new image.
Can anybody confirm this or can anybody help me ?

My OWON HDS272S: SW-Version: 3.3.3 - Ser. Nr.: 2128xxx - Mainboard date: 2021-03-24 - Mainboard Version: V2.0

[rn777]

Can anybody confirm this or can anybody help me ?

In my owon 272s, this bug is not confirmed.

[saresigi]

I solved the problem myself.

If you switch on the USB drive from the Scope (in my case G:) in the "preview pane" view in Windows Explorer, you can see the image of the "FIRST" saved file (see attachment "Preview.jpg").

You can delete these files in explorer, but the next time this "preview" is available again.
This image cannot be changed - it's always the same.

If you now double-click on the corresponding file, the image will be opened in an image editing program (see attachment "IMAGE1.jpg") you can see the "content" of the file.
(I had to reformat the file to "jpg", "bmp files" cannot be uploaded here in the forum).

This is then the saved image from the scope.

Can someone explain this behavior to me.

Whether this can be called a bug is up for discussion.

Many thanks to "tly".

I'm just wondering why I've never encountered this problem before. I've been working with MS Windows for decades now.

[blurpy]

I'm just wondering why I've never encountered this problem before. I've been working with MS Windows for decades now.

Probably because the scope doesn't have a clock, so the timestamp is always the same. The OS doesn't know the image has changed.

[bhgsmservis]

Hi,
Read this topic many time because I am thinking to buy model HDS242.
Dont find many information about this model in this topic about FW update for this model.

Anyone use this model HDS242 ?
Plesse share info?

Saga Continues.......

Thank you tly for tagging me about 3.3 firmware for for V2.0 board. It's the right firmware for my unit and serial but unfortunately OWON firmware doesn't check board rev, FPGA rev. it only checks for sequential numbers in firmware 1,2,3,4,etc so with me flashing 5.4
it thinks I have the most up to date firmware and it won't flash, (Go figure). Man what a mess, I'm trying to do all this with no screen also just from manual F2,F4,F1,etc.

I tried modifying "TABLE.BIN" to 3.1.0

 "2                   HDS200  F 3 A 4 1 - V5.6.2              2124920             HDS272S_1           HDS272S             OWON"

but it seems it's overwritten on scope start up BEFORE flashing, plus lot's of encrypted checksums and such I'd have to modify. Bummer.

So Thanks' for everyone's help but I think I'm screwed for now.

I have firmware 5.6.2 and 5.6.3 for my device vith h/w revision 3. Now installed firmware 5.6.3. For experiment i installed version 5.6.2 over 5.6.3. Previously i rename file in this Scope.upp format. The firmware was successful writed and the software version was downgraded. You need to repeat the software installation procedure.

[harddkyss]

O wow, Really?!? hmmmm maybe I'm hitting wrongs buttons. Upon powering on (in DMM mode) I hit SYSTEM,F2,F4 then F2 then power off, then back on, but it never automatically reboots like OWON say's after firmware updates. does that seem Correct? keep in mind I'm doing this blindly so I can only go off sequence of key's.
Thank you for helping me!

[tly]

hmmmm maybe I'm hitting wrongs buttons.

connect device to computer USB port

[power on] > [system] > [f4] > [f1]

internal scope memory should be available like drive.
copy update fw file.

press 3 times the key combination (to be sure you hit the right menu):
[system] > [back] (is the arrow key in upper right side)


[system] > [f2] > [f4] > [f2] > [power off]

disconect USB cable

[power on]

wait for ~5 minutes.

[harddkyss]

Ok, I did that several times and it just beeps 3 times and turns off, then I manually power back on and and no display still. It powers off quick maybe 3-4 seconds after I press power button and should be flashing (Thought it took longer than 3 seconds). and the "Scope.upp" file is gone from drive. But hey thanks for sharing the correct sequence of keys, at least I know the correct way now. Mine Model is identical, same board rev, etc except serial number, mines 2124 and yours I think is 2128.
