amazing Bridge system and voltage compare voltmeter, really high resolution and accuracy even today it works fine and stable, you need a 5 digit meter to win over this one,
design was released in 1967 my unit is from 1968 zener serial and date sticker still original,
this is my Fluke video number 11 :-)
mains power usage 1.8Watt all transistor design, very much ahead of its time.
a few different models exist in this series the 887 893 and so on.
