You're wrong, it weights only 9kg = 20lb
Here's one that weighs 48 lbs (22 kilos), and measures DC Voltage...
Oh, and frequency, too, to either 300kHz or 1.2MHz, depending on options.
If you want to measure AC or resistance, that's another box, nearly the same size as the meter (meter is 19 x 7 x 18-3/8"; same height and width but
only 17-1/4" deep for the AC/Ohms unit) that's a svelte 43 lbs (19.4 kg) that plugs into it.
You've gotta love old test gear!!

So warm and beautiful digits...
Dymec was Hewlett-Packard's brand for industrial automation-type stuff. Note that if you turn "-dy-" 180 degrees, it reads "-hp-".
