Yesterday I was making a 200PPM cell of Colloidal Silver when my multimeter, which I’d wired in-series to the anode as per cfnisbet’s excellent instructions and pic elsewhere on the forum, suddenly went from showing a constantly varying mAmp current (as it should) to displaying a big fat, still ‘0000’.
I switched the meter from 20m to 200m just to see if it would spring back to life and when it didn’t I opened up the multimeter and checked the battery and found a single (internal) fuse, which seemed intact. No repair affected. Because it was quite an old multimeter (that my dad had given me), I wrote it off and bought a replacement today.
Thing is, during its very first run, a 500ml properly set-up cell in which I was intending to create c. 200PPM, the very same thing happened again. About eight or so minutes into the process I was checking the electrodes and was making a very slight adjustment of the cathode and once again the lively ever-changing mAmp display became a fixed, lifeless, corpse-like ‘0000’ again.
What happened? Please bear in mind that other than as a tool for Colloidal Silver generation, I have no experience of using a multimeter and so might have done something very basic wrong. Have I inadvertently (no, stupidly) shortened the circuit and blown a fuse, or broken the multimeter? If so, is it repairable or am I becoming another one of irresponsible consumerism’s useful idiots? What’s really confusing me is that up until two days ago I’d been using the original multimeter successfully without issue in every run of Colloidal Silver I’d attempted (and was travelling from Tony Pantalleresco Colloidal Silver roughness to beautifully clear, well-formed nanoparticles, thank you Kephra et al).
I hope somebody can help me see what I’m doing wrong and help me understand why this problem is happening with me, because at the moment my foggy brain has no idea. Thanks in anticipation.
