Hi Everyone!
Sorry for interrupting you, but I would like to ask your help. My current main DMM is starting to act funny from time to time, so it's almost time to get a new one and then see if I can fix her or not. S I would like if you guys could recommend me a few DMM, or DMM families which I should get or look into. I live in Europe, so most of the Fluke's are out of the question, since I have to pay extra VAT after them, which blows them out of my budget. Maybe the cheap 17b is a contender, but I would like to hear other ideas. After I heard some recommended types, then I search trough what I can get and choose one. I'm trying to not to nitpick, so the requirements will be as short as possible.
Budget: ~175-200USD/130-150EUR (the 200USD/150EUR is really the absolute max.)
Requirements:
-uA-range
-TRMS
-fairly fast update speed at least for analog bar if it has one (analog bar is not part of the requirement, just the update speed)
-frequency measurement at least 100MHz or higher
-some input protection or to be able to upgrade it
-RS-232 with some description (not absolutely required, but would be great)
-9V battery (I have to change my batteries far too often if they use AA/AAAs, but but I can continue living with it if needed)
-decent accuracy/resolution
Things I don't really care:
-auto or manual range
-Back light
-internal log (with RA-232 and some description I can make it log into an SD card)
Mostly I work with low energy circuits, so around 70% of my time is around 3.3V/5V. For around 20-25% is up to 20-30V, the rest is around 100-230V around the house, but for this I have other meters. I'm usually staying below 1-2A.
I've already looked around and I looked at the UT-71 series. My problems with them is the accuracy (30 digits in ACV) and the input protection could be better, but there are some way to improve it at some extend. Voltcraft is almost the same as Uni-t, but it was redesigned and got better input protection, but it's harder to get.
Thank you for your help in advance!
P.S.: I would be happy to put this topic into the Test Equipment part, but it seemed more appropriate in here as the other is full or reviews and tear downs and equipment problems.
