And about displayed frequency:
Connect the probe to signal generator
Set to Peak detect.
Set Signal generator to Square and 1 -> 10 KHz
Check displayed frequency on scope.
Set Signal generator to Square and 70 -> 80 KHz
Check displayed frequency on scope.
(Optional: use Auto button, change frequency on signal generator and check the result on scope).
----
Peak detect in use. Also, notice the arrow that shows trigger level on right.
Hint:
Good luck
For those with HW version 3.0, here is firmware version 5.6.2 for HDS272S (it might work with other devices but I would not take the risk and I assume no liability for any bricked device). Best is still to ask Owon directly to make sure you have the correct version.
The file includes FPGA + OS upgrade.

@rn777 - I have no idea what you mean re triggering - the trigger line is visible, and adjustable, in both AC & DC coupling modes. Obviously it disappears once it is set.
Just for the laughs, I think I shall email Owon the version 5.6.2 firmware, and ask "Here, would you like this upgrade?" since they didn't bother themselves to reply back with it attached, after THREE emails.
Hi Folks - first post, be gentle...
I have been reading up on the Owon handheld scopes and I'm keen to know if anyone has any experience using the 'Single' trigger mode.
I'm looking for a portable device that would help me onsite to look at vending style equipment - such as coin mechs and note validators. These device normally output a pule per dollar - so one 50ms pulse for a $1 coin and two 50ms pulse for a $2 coin with a 50ms gap. Pulses from this gear can be either AC or DC depending on the type of vending machine.
I have a cheap Hantek digital scope I normally take onsite which I set to single trigger mode to 'capture' the waveform which lets me measure the length and amplitude of the pulses.
The Owon HSD200 manual says these handheld units can do 'Single' trigger which reads "When a trigger is detected, a waveform is sampled and then stopped" - which sounds perfect.
I'm just keen to know if anyone has and real life experience using single trigger on these units?
Thanks in advance

So I got now the OWON HDS 242S, but I have an issue, because this damn thing is in Chinese and I can not switch it to English as this is nowhere written...
Why the heck don´t they just add a note somewhere on their page.

To Owon's credit, they actually did include details on how to change the language back, in the upgrade instructions PDF in the firmware attached to post 83 of this thread. I'm not sure why that PDF wasn't included in the latest upgrade zip that was posted.
So they really "forget" the settings on updates? Really???
I didn´t yet update it, because I was otherwise engaged, to look how to find out the current firmware. That was the plan for tomorrow.
Let´see what I got so far.
Please I need Help!! I flashed V5 firmware on an older version board (2.0 stupid me didn't know owon had different board rev's) and it essentially bricked the display portion. I do have button functions but no display and can still flash new firmware so if anyone has ver 3.1-3.2 for VER 2.0 board HDS272S, PLEASE I need it badly!! it would be extremely appreciated
Thank you very much!
