Good morning Ned....but never let it be said I would stray too far off thread

Yes the original post included an explanation of the performance features of the Multimeter in question
As we know, Iron [Fe] is an excellent conductor of electricity...it just so happens that the blood in our veins contains Iron [Fe]

I have been assisting an Associate Professor in Wollongong in understanding and determining how the various Iron [Fe] levels in my blood can be accurately measured using my specially modified $25.00 home multimeter to measure the Iron [Fe] in my blood
As we can see, three Ferritin [Fe] levels [668H, 544H & 406H] levels in my blood were marked with an
H which means
HIGH, this is where the Multimeter setting 'hFE' is used to detect such abnormalities
This process is in an early stage of development and we are also using my specially modified $25.00 Stanley metal detector to establish just where the Iron [Fe] loaded blood veins are located in my left arm
Associate Professor Raj....thinks we could be on a real $ spinner here....so watch this space

So from here, I rest my case in the usefulness of home multimeters here on MBM.......Derek
