My first-paycheck gift to myself is a brand new Rigol DS1054Z. I gave it network access and have installed the hack and it is working properly as a DS1104Z. Is there any use and maintainence tops I need to be aware of?

The ground clip of the probes is connected to mains earth. Anything you clip it onto will therefore connect to mains earth. If what you're examining isn't floating then magic smoke can escape from it (nb. the scope should be OK unless you manage to pass enough amps to melt the probe lead).
On-screen numbers are calculated using the data on screen. For the most accurate readings always zoom in as much as possible on the area of interest (both height and width).
Apart from that, just read the manual and enjoy it.
Just check if it has the latest firmware installed and have fun with it.

My unit is running firmware 00.04.02.SP4 on hardware 0.1.1 (as reported in the system information screen.) Is it okay?

Seems very old to me. Latest official firmware is 00.04.04.00.07

Where to find the latest one? And what key combination you are talking about? There are multiple Menu buttons.
To display the full version information:
- In the trigger area on the front panel, press MENU > MENU > FORCE > MENU <<< press this sequence very quickly
- In the menu area, press UTILITY > SYSTEM > SYSTEM INFO
Normally you can download the latest firmware here:
http://int.rigol.com/Support/SoftDownload/3But Rigol removed it because there seems to be a problem with the latest version.
Conract Rigol for a firmware update and they will send you a link where you can download it.

Is there any use ... tops I need to be aware of?
As with any scope, the probes and probing technique are important, since they are part of the circuit and the oscilloscope.
Make sure you use the right type of probe for the task (e.g. HV, Z0, current, differential, isolating, active etc etc) and that you use it
safely and correctly - particularly w.r.t. that fictional entity called "ground". Classic examples: a standard *10 "high" impedance probe self-resonates at ~100MHz, and at high frequencies its input impedance is
lower than so-called low impedance Z0 probes.
FFI, see the references at
https://entertaininghacks.wordpress.com/library-2/scope-probe-reference-material/
Use 'x10' mode.
Don't try to use the probes in 'x1' mode until you understand why you're not supposed to do that.
Like with any other equipment that can: Self Cal often.
Talking about the ground issue: I found that the USB connector is able to power an Arduino or ESP8266, with common ground. So, would doing that and leaving out the ground clip entirely be a good idea? I guess starting at some frequency, you want to keep the loop small and use the short ground clip wire, but for a lot of stuff, this should work, shouldn't it? It wouldn't be the first time that I have a hard time finding a good position to place ground on a miniaturized µC board.

I never really thought about doing that, the dev board is usually connected to a PC for software uploads.
There's no reason it won't work though. Give it a try and see what happens. Have a look at a square edge and see if you get more ringing (or not... If the entire board is at the same potential as the 'scope then I'm not sure what happens
).

Sure, that should also work, as PC USB ports are also usually at earth potential. Just makes the loop even bigger.
I actually did it and it worked for the stuff I did, but that was basically digital stuff in the lower kHz region with not much interest in analog stuff (just got the osci and mainly finally debugged my IR hub). So I am not sure if that would really be a generally good tip are would fall apart very soon.
In Any case it is surely better that letting out the magic smoke by connecting the clip to the wrong contact.

Yes, it will work. I'm just worried you'll get a lot more ringing on fast rising edges (I think you will, otherwise what would be the point of the little spring thingy for the probe).

Well I was seeing ringing even with the ground clip, probing a square wave right at the pin of a STM32F103 pushing out square wave with its PWM hardware.

Try using the spring (see other thread), it really helps.

Heh... whenever you have a spare hour, anyway.
Warm it up for 30 minutes first, then run the self-cal routine.... and it takes 17-19 minutes to complete the self-cal.
The instrument is indeed sensitive to changes in ambient temperature. I get DC offsets appearing whenever the room temperature changes by a couple of degrees.

Hah... I see you have Boot Version 0.0.1.2. Unfortunately there seems to be no way for the _user_ to upgrade the Boot Version. The "firmware" updates that we can install only change the "software version".
Since you have that early Boot Version and are still running an older "firmware" version, you may still be susceptible to certain bugs that were found, like the Freeze Bug and the Measurements Fail bug. There are threads talking about these bugs if you want to check for them.
You should also know about the "fifth grey button reset" if your scope ever freezes and becomes non-responsive.
Press this button repeatedly during the bootup process, and the scope will reset to "factory defaults":

Really ?
Shite that's slow.
Let me do one for a 1102X, bet it's under 4 minutes......I lost...4 min 5 sec.
SDS2304X........2 min 47 sec, but these have a Quick Cal too that Cal's on the fly. Haven't used it for a long time but IIRC it takes just a few seconds.
No restarts required for either series of these, if fact AFAIK any of the Siglent DSO range.
Just ran a self-cal to check for certain:
Start time 23:06:30
End time 23:25:01 (not including restart after calibration routine finishes)
This is the third DS1054z unit I've had in my possession and all of them have taken about that long to self-cal.

I feel pitty for you that you are so desperately trying to promote your siglent stuff in every thread here.
Is business going that bad for you?

That only has 2 channels... DS1054Z has 4!

What's the matter Karel ?.....do the facts hurt ?
Confirmation by alsetalokin4017 indicates the Self Cal process of 1054Z's is pitifully slow. Period.
I've not seen it mentioned before, why shouldn't I comment ?

It's excellent, 2016 was a record year. How about you ?

2 min 47 secSo somebody with a DS2072A chime in with their Self Cal time and then there can another for fair comparison.
