OK Bob,  what is it  you do not trust?  The  accuracy or ?  As a tech person,  you must really  be able to  "trust" [your] meter.  So, I  guess you may not trust the accuracy?  OK.  Perhaps you will tolerate a degree of accuracy?  I use a Fluke 87 in the workplace.  But the ohmmeter sucks.  I am an older guy [58].  So I  got schooled on Simpson 260s.  I still  like  them  for  higher voltage.  But I do  like the Fluke for reading  down in the mv range- for sure.  All the meters  you have  are  good items.  Periodic calibration is a good idea-  makes you feel safe.  73 Russ.
