Hi
My Fluke 189DMM rotary contacts are missing. Can anyone tell me where to find them or any other way to make it?... -
Hello experts,
I recently purchased a used Fluke 123 Industrial Scopemeter from an online Japanese auction site (jauce.com). It has now been delivered. Unfortunately, I overlooked the fact that the seller neither guarantees its working condition nor accepts returns.
When I power it on, the backlight comes on, but there is no image on the screen. After opening the device, I noticed clear signs of previous soldering in several areas (photos attached). It seems someone attempted repairs before.
At this point, I'll have to try and fix it myself. Has anyone here... -
I am repairing a Fluke 335 clamp meter. After contacting fluke it appears there is no service manual or circuit board/ component list available. I have determined that there us a faulty PNP bipolar junction transistors shown in the pictures. I am having trouble sourcing this transistor. I pulled a good one off of the board and tested it with my component analyzer but I cannot find anything that matches the specifications. Any help locating this part or a replacement would be greatly appreciated.
Thanks... -
Hi, I have a 11 year old microwave Siemens and the main function selector switch is a rotary type. It goes bad every few months, there are carbon (?) pads and the metal contacts that drive on them create concentric circle tracks from the residue.
I clean the tracks and the metal contacts with IPA and it works few months again. Here you can see the contacts:
Once I tried this contact cleaner: Kontakt 60 https://www.tme.eu/Document/3f58feb2...TAKT60.DTE.PDF, but it only lasted few weeks, so probably not a good choice.
Is there any... -
Need a new (used) DMM and there are two in the area for resonable prices.
The Agilent U1242A is 63 GBP (about 80 USD)

The Fluke 179 is 55 GBP (roughly $68.00)

Kinda leaning towards the Agilent.
Anyone think that is a bad idea?
