Hello All, I just picked up a 731b that I would like to mount in a rack with a back up UPS. I know that Fluke made the "Rack Mounting Kit M03-205-605" These were used to house up to four of these standards in the space of 3U, I think. The present day version of this is the Fluke 734a-7001. Does anyone know where to find one of these older rack options or know if the present day 734a would fit the older 731b standards? Cheers, David
