Fluke 52 II PCB missing passive component
Blynski:
I am trying to fix my dad's Fluke 52 II and it appears to have multiple issues. Firstly, half of the header contacts had broken solder joins which I repaired. Secondly, it appears to have some damage and a missing passive component (probably a capacitor based on how it is acting). Attached is a picture I found of a good board with the missing component circled. Does anyone know the correct value of this component so I can order one and replace it (or someone with a schematic)?
fzabkar:
The colour is reminiscent of a precision resistor. What resistance do you measure for the "2742" part and for the other unmarked part?
Blynski:
Thanks for the hint on it being a resistor. I’ll take some measurements tomorrow and report back.
Assuming you are correct I would still need someone with a good board or a schematic to help me out on the needed value.
fzabkar:
The Linear part is a dual precision reference:

That would lend support to the precision resistor idea.
Blynski:
Based on taking measurements on my board, I would agree that they are in fact resistors. Picture attached of the measured values. Essentially two 27.4k ohm and one 5k ohm resistor. So at least I know I'm looking for a precision resistor, but still need the correct value...
