This seems somehow familiar.... ;)

247k BMP vs. 7.31k PNG might seem a little familiar too. 😉

I find it interesting that not only Easttester has a “problem” with providing a universal screenshot function.
So this doesn't seem to be trivial.

IMO it is trivial. The problem with the Hioki is that there are no physical buttons. The "Save" button appears on the screen to capture screenshots, but only on the measurement screens. So they would need to add that additional touchscreen button on all screens when activated. Which really should be active by default.
In the Tonghui LCRs, you hold the period . button down and it captures any screen.
Since it has physical buttons, EastTester could follow the TH/ST logic and assign a long press to any button to capture a screen as long as it doesn't already have a long press function.
Really what it comes down to with Hioki, is that they didn't see a need for the function, so they didn't add it. Like the other stuff I mentioned in my list. It all seems basic to me, but apparently nobody requested those things.

hi KungFuJosh,
Given yours posts... you know a lot about this device & LCR in general.
I admit I have a limited use of my Shannon Tweezer LCR meter (bought because not too expensive, but so far : I admit I lack some basic knowlegde to get the most out of it).
When you have time... please anwser the following questions, to help "dummies" to understand how usefull a LCR-meter is : (or anyone that masters this topics like KungFuJosh :-) )
1. for what kind of inquiry, you need to use the Hioki ? in practice.
Is it vs PCB traces impedance ?
Is it just components on PCB measurement ?
Is it about trace impedance vs power delivery ? or signal delivery ?
I guess you use it for more fine measurement than a Shannon Tweezer user :-)
2. the Hioki extends to MHz range : how this makes a diff vs low end LCR-meter that don't go so high ?
3. related to previous question : what's the diff vs the results given by the Hoiki vs a cheap LCR-meter ?
4. using the Hoiki, is the limiting factor vs "fair results" => the fixture ? I mean : the way to measure matters a lot vs the results ?
5. as a dummy vs LCR-meters, when I see 5MHz MAX, my brain struggles to find how usefull such a tool can be when I deal with signals far above 100MHz...
Is this Hoiki relevant vs trace Z measurements when the signal is so far away from the "5MHz max" ?
I stop here. :-)
Anyone can reply to help the dummies.
And of course, anyone can urge the dummies to get more info here & there to be "less" dummy vs that topic :-)
KungFuJosh:
I know a bit, but there are certainly people on here that know a lot more than me. I'll take a shot at your questions anyway. 😉
1. The simple answer is that I use the Hioki when I need higher accuracy, or a higher test frequency range.
2. Higher frequency range is required for specific devices or component values. For example, some components like 100nH or some 100µH inductors are tested at 1MHz or higher. Many high value capacitors will require low frequency testing, some lower than 100Hz.
3. Accuracy and the ability to test devices that won't work in the limited frequency range of cheaper meters.
4. Testing method (fixtures or otherwise) and open/short/cable correction always matter if accuracy is desired.
5. This one is a little beyond me. I use the Hioki to test devices looking for good accuracy. Some devices are beyond the capabilities of it. If you're trying to test a device for a higher frequency range, you might get a general idea. For more accuracy, you need a tool capable of testing in that range like a VNA.
Thanks,
Josh
