I skimped through the post about DMMs not compliant to their specifications and I am curious about not meeting CAT standards by the BK 2709B DMM. Following the manual part regarding input protection:
"Input Protection 0.5 A/500 V & 10 A/600 V fast blow ceramic fuses".
There is a comment in the post that the meter actually has 2x500V fuses so I am thinking if replacing fuses with 600V version will make it better. I noticed that some meters have their fuses spec'd like e.g. @0.5A/600-1000V & @10-15A/1000V. Does anyone tried swapping in 2809B?
I am wondering if putting there 600V fuses will make other parts of circuitry blow. Is it a very serious issue? Ideal 61-342 has it marked as minor inconsequence and not following the specs. Thanks in advance for explanation.
