AC adapter info for Fluke 8060A?

Dec 28, 2004 3 Replies

I have a Fluke 8060A handheld DVM, but no user's manual, and no "wall-wart" power supply. Nowhere on the case does it indicate the voltage or current needed for the external power input... it doesn't even indicate if it's AC or DC, nor what the polarity should be in the latter case.



Could someone please let me know what the official Fluke AC adapter's output ratings are?



TIA, Brian Aase

(adobe pdf - 6.18 MB) ~15 min d/l @ 28.8

from page 22 of pdf:

Under "Specifications - Power" it has: "Single standard 9V battery (NEDA 1604), or Fluke A-81 Battery Eliminator option available for 100, 115, or 230V ac operation.

Under "Specifications - Battery Life" it has: Typically 170 hours with an alkaline battery. BT appears on display when approximately 20% of battery life remains.

Whatever a "Fluke A-81 Battery Eliminator option" is?? Fluke doesn't want to tell (that I can find).

Ah-ha - looking at page 123 of the pdf it looks like a tip Pos 9V source would fill the requirements. Maybe open it up & check that the "Battery Eliminator Jack" is wired the same as the schematic.

I did find info on a "Fluke A81 Battery Charger / Eliminator" at:

for $31.01. I know nothing about the company - just found it via Google.

Suggest a well regulated 9V source (mostly for over voltage problems) & not just a 9VDC wall-wort. A 9V alkaline battery is maybe 600mAH. 600mAH for 170 hrs. = 3.5mA.

Any wall wort that puts out close to 9VDC _may_ work but I would not want to trust _my_ Fluke to such unknowns.

Any 9VDC supply rated at >3.5mA should work but to be a little safe try finding one rated at 25-50ma or better. Maybe a 12VDC supply & a 7809 or

317 with 2 caps & no heat sink to regulate it down to 9VDC.

Double check the above information before using - it should be correct but... you know what free advice is worth :)

Hi Brian,

I have a Fluke A81-115 ac adapter for the 8060A. The label on it reads:

5.8 vdc @ .15 adc. The outer sleeve of the connector that plugs into the 8060A is positive and the inner jack is the negative side of the supply. The 8060A manual warns that you need a high quality ac adapter like the A81-115 to maintain the common mode rejection of the meter. Good luck.
