Had a few minutes and turned on the TH2830 and IM3536, let them warm up for ~45min and grabbed some 0603, 0805 and 1206 100K resistors. Had some standard 1%, and some 0.1% and a couple low TC (15 and 25ppm) types.
Edit: Remember to always let these instruments warm up with the measurement fixture attached
Did an open/short cal with SMD fixtures, one on each instrument. Open was ~1206 spacing, short with plungers together under normal pressure. If we were doing a serious measurement, then the short would be done with a zero ohm SMD device of the same size as the DUT, and the open would be done with the plunger spacing same as DUT.
Both instruments agree well in Impedance Magnitude, Angle, Equivalent Parallel Resistance & Capacitance measured at 100KHz. The equivalent capacitance seems reasonable for these SMD devices (~0.05pF).
Anyway, the TH2830 is certainly a capable LCR meter and glad we have one on the bench to supplement the more expensive IM3536, a number of years past wise investment indeed
Edit: Will post results if interested but don't want to clutter up the thread. Should have done DCR measurements as well and compared with our KS34465A, but didn't
Added per request, here's a few measurements including DCR and a KS34465A DCR measurement.
