Most people are fairly familiar with multimeters, or DMMs. But what did its grandparents look like? I have got hold of a 1977 multimeter, so lets see what's inside!

The ceramic board with the "antenna" like traces will almost certainly be the current sense resistors. (Or current shunts as people sometimes call them.) MK

Thank you! I'm glad you enjoyed it! I loved this device as it was, but having seen it in pieces, it's a work of art!

Agreed, looking back at all of the older gear I used to use, they look like tanks compared to the newer use and toss devices.
