As expected, voltage
without DUT                       0.613V RMS
with 47.0 Ohm resistor        0.159V RMS       
with 0.24 Ohm ESR cap       0.014V RMS
I have also uploaded here the Cyrustek LCR bridge ES51919/ES51920 chipset information and the datasheet for the multiplexers.

vPP only at 0.47  :-+

good review and photos. I don't think it would be anywhere near as hard as surgery. The only hang-up might be the dimensions of the replacement jack sockets, as most people would still want to retain the same case. The one advantage of the mastech and any meter with the slot style sockets is that it is practical to make your own kelvin adapters from double sided copper-clad pcb material. You don't even need to plate the copper, it is fairly easy to burnish and clean the contact patches each time you want to switch adapters.

Do you have any issue with the viewing angle of your UT612? I bought one a while ago but the LCD is terrible. I can barely see anything if I look directly at it. It has to be viewed from like a 30 or 45 degree angle to see things clearer.

From above photos, it doesn't look to have this problem, photoshoots of your lcd from various angles please.

I tried, but somehow it always looks better on photos. In real life the display is really pathetic.
