#186925 - It's missing one thing ... for sure ...
Responding to: Jim Granville's previous message
Jim Granville said:
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 400A/4000A/40mA/400mA/10A (0.5%+10)
AC Current 400A/4000A/40mA/400mA/10A (1.2%+4)
Resistance 400O/4kO/40kO/400kO/4MO/40MO (0.5%+10)
Capacitance 4nF/400nF/4F/40F/400F/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 ?
not that I'd need one ...


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.
