URGENT! My Fluke 187 multimeter stopped reading voltages (ac and dc)

[The Guy]

Just wanted to let you know for future reference that I just installed a Kaddock 10Mohm 1% resistor I ordered over the broken resistor network and my dear Fluke 187 multimeter is working like a charm again!!! So awesome. Not sure how accurate yet, but I compared some measurements with the cheapo multimeter and it's perfect, also measured some good quality caps and resistor and reads also perfect.

I thought I'd lost the fluke.

So, thanks fellas!

Take care.

The problem with that is unless you effectively disconnect the broken section of the resistor network (with enough clearance to withstand 1KV)  you can never trust the meter again as if you use it on higher voltages, the break in the resistor network may flash over and leave a partially conductive path.  If it does that, it will, in parallel to the Kaddock resistor, drop the total below 10Meg and cause the meter to over-read.

I am aware of that... I don't have a high voltage source at hand, but I did measure 220Vac without any trouble. If it happens that an arc gets formed through the broken resistor network I will gouge away right above the main leg the resistance substance, like 0.5mm wide to make sure no arc is formed as you suggested. Thanks.

If you can, crop and desolder the 10Meg leg of the module and add a sliver of Kapton tape over the stub of the leg to increase the separation.

...or maybe just cut the leg altogether and solder the kaddock leg on the pcb instead

That's what I meant - remove the leg, add extra insulation because the clearance may be insufficient for 1KV and connect the replacement resistor to the PCB pads.

oh... ok, yea good idea
