So just for fun, I popped over to ebay, and searched for [multimeter capacitance], and then sorted by Highest price first.
First one with a picture showing 5 full digits, is ~$100 UNI-T UT60H It also does 4-20mA, you left off your list by accident ;) I believe I saw one or more of those on eBay, though I've really got no use for current loop. some of those scope-meters in the $1500 range seem to meet most of my wish-list, though I really don't need it to be a 'scope. DC Voltage 4V/40V/400V/1000V (0.1%+5)
AC Voltage 4V/40V/400V/750V (1%+4) DC Current 400µA/4000µA/40mA/400mA/10A (0.5%+10) AC Current 400µA/4000µA/40mA/400mA/10A (1.2%+4) Resistance 400O/4kO/40kO/400kO/4MO/40MO (0.5%+10) Capacitance 4nF/400nF/4µF/40µF/400µF/4mF/40mF (1.5%+20) Frequency 4kHz/40kHz/400kHz/4MHz/40MHz/400MHz (0.01%+3) Fused 10A Range Y Yes, it says 400MHz - do we believe that ? I'd have to see the probes before I'd take a guess. LSB is not so easy to nail down, but if we assume this
[39999 (on functions of DC Voltage, DC Current, Resistance, Capacitance, Frequency, EF Function and 4-20mA Loop)] Suggests 0.1pF LSB on that 4nF range, and 10 miliohms LSB on that 400ohm range, and .01uA on that 400uA range. Frequency LSB is a disappointing 0.1Hz; Properly done, frequency should simply give 4 1/2 digits. ie 49.99Hz for example. Perhaps that is a chinglish/typo issue ? So I dig some more, http://www.uni-trend.com/UT60h.html the manual actually says ["40Hz, 400Hz, 4kHz, 40kHz, 400kHz, 4MHz, 40MHz and 400MHz."] so that is a typo. 39.999Hz will display. Only thing missing is a PC link ? Edit: Turns out you can have that too, with a choice of precision/price. http://www.uni-trend.com/newproduct.html and down to 0.025% DCV, .08% DCI, and 0.3% R So, what's missing from your wish-list ? Only serious omission is a manual written in proper English. I recently bought a meat slicer ... one of the deli-size ones, from China, albeit a manual feed one, with which I'm quite pleased, except for the manual. I'm very tolerant of translation, having been a "Dolmetscher" for a number of years, myself. That was many decades back ... but I still tolerate someone's best work, so long as it's of some use, which this one wasn't. I had to ask my brother-in-law who is a retired butcher, how to take the blade out for cleaning. Everything else was quite apparent, aside from how to read the manual. RE |
