Fluke 101 Multimeter Teardown

[dexters_lab]

picked up one of these Fluke 101 to sit in my toolbox, thought it'd take it apart and share.

Bought from Ebay, £42.00 including the shipping

It doesn't measure currents but it has a 13.8V 750mA fuse (LF075) on the positive side of the battery connector, followed by a beefy diode (zener?) to protect the circuitry.

i have to say i am quite impressed for the money especially on the inside. Though there is no replaceable fuse, but i guess at this price point if you fry it, just buy a new one.

range switch has a good feel to it, the display is nice and clear. Continuity test is latching and fairly quick but does miss a few flicks if you do it quick enough. The test leads are nice and long with a rubbery grip feel to them with fluke branding.

biggest downside is it's not True RMS

sorry to all, i had not noticed a similar teardown had been posted up before by awardcat last year, i did search but it didn't show up!

The test leads and probes are too big for the meter really. I replaced them with a set of leads I had lying around, which are shorter and smaller, for convenience. Of course, for high energy stuff, the original leads should be used.

The meter is well protected and will have to be subjected to some serious mishandling before it expires.

No need to apologize because I like seeing another set of clearly focused photographed pictures from a different angle or perspective as it may help identify components for future repairs.

+1 , and also possibilities of seeing different versions, thanks for sharing btw.

The more, the better ;-)

I have a similar one (107) and love the small size. The 101 is even smaller.

  i have a 107 on order as well to replace my old Mastech
