Old Fluke Multimeters
cnqhdszq:
I am learning english through reading this thread ,but it is hard to find this thread in "Test Equipment" group |O , so I have to post these words . hope somebody to help me ^-^
yo0:
hello, anybody have a picture of the 300v version of the 8060a? i never have seen any. unless the exterior labels be the same in both 1000v and 300v (i doubt it), if yes how to know which is which? :-//
best regards
Pio

In 1990, the "CAT standards" (Measurement Categories per IEC 61010-1) for meters were released. The Fluke 8060A can only withstand 300V on its resistance ranges, so it can only meet CAT I 300V. To qualify for a "CAT I" label, the voltage ranges were reduced to 300V for both DC and AC. Otherwise, I don't think the meter was changed: it is no safer than the unmodified 8060A.
It can be recognized by two differences from the normal model: the presence of "CAT I" below and to the right of the red jack, and the highest voltage range is marked "300V \$ \simeq \$ " instead of the normal "1000V DC / 750V AC". In addition, the maximal voltage limits printed underneath the jacks are lower (300V MAX from common to earth instead of 500V, and 300V \$ \simeq \$ from red to common instead of 1000V DC / 750V AC MAX).

My copy of the manual says "Overload protection: 500V DC or RMS AC" for the resistance ranges. :)
It also says things like this for the voltage ranges:
"Overload protection: 1000V DC or peak AC continuous, 20 seconds maximum on 200mV and 2V ranges above 300V DC or RMS AC"

Some issues of the manual did contain misprints. But I think you are right that it was intended to have 500V peak protection on Ohms, as that was advertised. The copy you can download from fluke.com does say 300V: http://assets.fluke.com/manuals/8060a___imeng0300.pdf
