Percussive maintenance Memes

Soviet-era multimeters: when precision engineering meets percussive maintenance. Nothing says "reliable measurement" quite like a device that needs to be calibrated with a firm slap. The GOST standard clearly didn't account for the fifth fundamental force of physics: hitting equipment until it works. Rumor has it these meters were actually designed to withstand nuclear blasts, but ironically can't handle being placed gently on a table without the needle going haywire.
