In celebration of World Metrology Day this week (May 20), here's "The proclamation regarding weights and measures, 1556", a mural by Ford Madox Brown completed c.1893, depicting the announcement that the residents of Manchester "shall send in all manner of weights and measures to be tried by their Majesties standard". The announcement seems to be received about as well as you might expect.

Do any of you have a SMU that can reach 1kV level? I’d like to do a simple (remote) experiment but my SMUs only reach 210V. Keithley 2410, 2470 or 2657 models would be ideal.

We are investigating switching losses of power transistors and we need to measure the output capacitance in a particular way.
