No repairs required for this unit, just some clean-up. The external clean-up has been documented in blog post Dirty Multimeter Clean-up, so most of the photos have been moved there.
Leaky capacitor issue discussion at EEVblog. There is also a video by Martin Lorton on the topic.
I need the knob of Fluke 189 as the contacts are miplaced.
i lost may Fluke 189 rotary switch contacts… can buy that things tnx..
None of the rotary switch parts are on the list of user-replaceable parts in the manual. So unfortunately, I do not know where you can obtain the contacts.
I have the same problem. Let me know, please, if you found the contacts somewhere.
Do you know where I can gets the battery terminal contacts strips, the whole set, like the ones you place on photograph 17????
My experience: I just repaired my Fluke 187. I had minor issues with some contacts (screen and power supply).
It took time till I realised that the rotary switch contacts can easily be lost during operation. Strangely, with one of them lacking, the Fluke seemed to work but could not switch off.
Thus, be very careful with these switch contacts when opening the device.
Please tell me. How can you dissasemble the knob ? From where you pull the plastics ?
I am afraid that I will broke something but there is much dirt beneath and I must open it!
This is the way I do it: Support the front cover, face down, on your work surface with two paperback books of equal thickness. Leave the area under the knob clear. Then take a banana plug and push down on the gray hex shaft. You may have to push hard, but it will pop out. Be careful not to lose those rotor contacts, they’re hard to obtain.
Does anybody know the replacement part number for the ceramic chip capacitor
that is connected to the Big green 100k Ohm resisters? You have a good picture of them in the third photo. One is positioned vertical and one is horizonal.
I saw your post at EEVblog. RIP. 🙁
can you tell detail about how to remove rotary switch mechanism form top cover? I am going to clean my fluke 87-IV case,but I’m too scared thant I’ll break them.
Any one has the fluke 189 main core chip? or just the board included the chip?
I have fluke 287 When I Push On Button Power Not On, But Blink Green Light On Power Button, can you halp me?
you sell a refill
Whats a 33-16 SMD
