I have that same HF Mastech meter for my main out side disposable.
I'm delighted to see such careful categorisation. I tend to just categorise my meters into 'bench', 'handheld' and sometimes 'vintage', but do you have candidates for all permutations of inside/outside, main/backup, disposable/quality ? Any other categories ?
Maybe
RecycledThis by far categorizes the majority of the meters I have looked at.
ModifiedMeters that I have made some sort of modification to for demonstration purposes.
RepairedMeters that were damaged during my evaluation that I was able to repair and they still meet there original performance.
DamagedMeters that ere damaged and I was unable to fully repair but are still somewhat functional.
DeadMeters that are non functional but still in use. 5KY provided me with a UT61E which is the only meter I have that fits this category. Although, it's nearing the recycle stage.
RobustMeters that I have yet to damage. Because I normally run all of the meters to failure, there are VERY FEW meters that fit in this category.
