  1. The UNI-T UT71D multimeter Part 1

  In part 1 of this review I take a look at the features, functionality, resolution and accuracy of the UT71D. In some respects I compare it to the Agilent U1272A. I use both the PentaRef and DMMCheck Plus from Doug at VoltageStandard.com

  Review of the UNI-T UT71D multimeter / DMM – 4000 / 40000 count, 0.025% / 0.05% DC accuracy, internal data logging for 10 000 values, PC data logging.

  If there is enough interest in this multimeter Franky will stock it on his eBay store:

  Or contact Franky for discount on my forum.
