New Rigol dho804 oscillocope

I use  the power adaptor provided in the accessories box and I connect it to the AC power source (220 V, 50 Hz ).

I must admit that I do not know how the customer protection laws works in Egypt, but I am almost sure that if you will contact the China vendor and ask for exchange or money back, they will arrange for equipment exchange.

The Rigol service just sent me the mail and said that "please try the following solutions:

• Press the power button and quickly press the BACK button on the front panel multiple times. This may reset any incorrect settings.
• Alternatively, place the latest firmware on a FAT32 USB drive, power on the device, and follow the on-screen prompts to upgrade the firmware.
• If these steps do not resolve the issue, please contact our support for further assistance by 'reply all' via this email.' But I don't know what is he meant by back button

I have a Rigol DHO924S and it comes with the same Liteon PA-1650-58 supply.

It works.

It is quite slow to boot up - maybe a minute or so.

michaelkellett  Ok, thank you. Do you know which the Back button in the front panel that Rigol service mean

It's not clear in the 924s manual but I think they might mean this key:

This one

Do you know how to ubdate scope firmware, I download the file from Rigol site "" rel="noopener noreferrer nofollow" target="_blank" data-e14adj="t">supportint.rigol.com/.../software-firmware-download.html"

It looks to me as if the scope must be working to update the firmware - you put the new code on a USB stick, plug into the scope and open the file. Which means you need to have it working well enough to work the disk management functions.

There is a .pdf file (which may have cold boot instructions) at the link you gave me but it won't let me look at it (no password) but you might be able to look.

There are some more ideas here:

Nope.  He has a 15V 3A PD supply (so could supply different voltages) but the manual he is reading says he needs 12V 4A.

 Hi  ahmedfotoh  you need a 15V 3A DC power supply with THIS USB C connector.

Please look on the back side on your scope:

So, if you have another device this is wrong. May be that Rigol provide a universal power supply.
But the cord with such USB connector AND with this coding pin must be mounted into the power supply.
In the manual is a caution (page 13) that you do not use the PS for other devices.

Here the official website:

https://www.rigolna.com/products/rigol-digital-oscilloscopes/dho800/

Please read careful the manual.

Well USC C has power wires that are "normally" mounted mirrored on the plug, but not a universal power supply.

So, you can rotate ("normally single voltage"), but not this for the Rigol.

 geralds  Ok , Thank you very much for this clarification, I understand that the my adapter i not the proper one and I need another one has 15V 3 A but it has the same terminal of Rigol no the universal Type C one?

How can I update its firmware without turn on the device ?

It is possible that the DHO8xx is different from the DHO9xx - but as you can see from the picture above my DHO924S is being powered and working with its own PSU plugged into the FNB58 USB meter and a standard (but good quality) USB C cable connecting the FNB58 to the Rigol scope.

Hi  michaelkellett 

TOP!!! Yes, your tip is right.

Both scopes use the same PSU, USB C / 15V 3A.  

for ahmedfotoh: Which power supply do you have, recommending, and where can he buy it?

...the USB meter FNB58 looks good.

...what are your experiences with your DHO924s?

Regards

Gerald

I'll try to get round to a mini road test of the DHO924 in a couple of weeks.
