DMM Check Plus Reference Standard Review

Today we take a look at the latest revision of the DMM Check Plus Reference standard. The DMM Check Plus is a fantastic tool for checking any DMM’s accuracy in the real world, especially if the user has more than one DMM that they normally work with (or if you are weirdo like me who reviews multimeters on YouTube).

My UNI-T UT8804N bench multimeter was tested in this video for the purpose of showing how this reference standard works.

This is an unsponsored video as I purchased the unit for the purpose of doing a fair and unbiased review of this reference standard (and incorporating it into my testing standards in future videos).
