As I mentioend, I don;'t think my 85 failed due to external impact. It
wasn't dropped. Nothing fell on it. Yes, it was in a tool drawer, with
fairly small tools in boxes. Not in a tool box with hammers, etc. I don;t
think a ruggedised version would have helped.
Given that I need the standard functions only
(including a good
continuity tester!), don't need excessive accuracy, and would like to b=
e
able to fix it if anything goes wrong, does
anyone have any
recomendatins? I am not conviced I should buy another Fluke, BTW.
I was going to suggest the Fluke 25 or 27 -- these can be had for about=20
=A320 to =A330, do all the basics (current to 10A, voltage to about 750V,=
=20
resistance to 10M) and are ruggedised, so pretty difficult to break. Put=20
it this way: if you drop it on your foot, expect a trip to A&E.
If you want a true fix-it-yourself meter and can live with a bench DMM,=20
While a bench DMM would be nice _too_, at this point I am looking for
somehting I can easily carry about, use in the field, etc.
And _old_ HP DMM would be nice (either BCD or GPIB interface, etc). But
they sell for excessisve prices on E-bay, even when they are 40 years
old. Yes, I could repair them (all TTL, etc), but...
If you're after modern, shiny and new, the Agilent
U1251A and U1251B are=20
nice. Really, REALLY nice. Big display, 4.5-digit 50,000 count, true-RMS=20
voltage to 1kV, current to 10A, resistance to 500Megohms, capacitance,=20
diode check and continuity. Also does temperature measurement (internal=20
sensor or external K-type thermocouple) and data-logging with=20
RS232-over-infrared output, which is handy. I've been using it to track=20
reflow profiles during SMD soldering tests.
Sounds very nice, but I'll bet it's not cheap :-). For that sort of thing
I'd problaby use my HP3421 anyway...
