This is a very unique open face 0-5mV dc panel meter with a latching contact feature was built in 1964. When the meter reads over 5millivolts DC the needle is captured by a magnet that latches it against the high limit contacts. This closes a set of contacts on the back of the meter (low current only or you'll burn these sensitive contacts). Once captured the needle is held until reset by applying 120VAC across the reset terminals briefly. This causes a set of arms to push the needle off the contact and back into normal operations (I'd recommend this be just a brief pulse to keep the reset coil from overheating). I have tested all the functions of the meter and they all work perfectly. The meter reads dead on at 2.5mV when tested. The meter is also totally sealed front and back. The back contacts are hermetically sealed in glass and the from has a rubber gasket under the metal trim that is in good shape. I particularly like this meter becase the movement and contacts are all exposed giving the meter a very unique vintage look. On top of all that, this may have some interesting historical value as it was surplussed from Los Alamos National Labs where it was probably in service during the height of the atomic weapons development under the A.E.C. I really hate to part with this meter, but I'd rather see someone put it to use than put it back on my shelf to collect dust.
