This was love at first sight. It is beautiful made and with 460 gram rather heavy for its size. It realy feels massive. No tear down pictures this time. I have no manual and there are no visible screws. They are sealed with some clay-like stuff. I do not want to disturb the turret mechanism.
The metermovement has a turret with several scales. With the red wheel you choose the wanted meter range. There is 6A, 15A, 40A, 100A and 300A scale. The scales have black numbers on a yellow background.
But this meter can also measures AC voltage. Those scales are 150V, 300V and 600V. This time in red
I do not know how old it is but I think it is an early version because in other pictures of similar looking snaps, the scale shows a more digit model number. The slide under the metermovement locks the needle. I thing for transport and maybe also as a mechanical hold switch.
It can measure resistance. The probe holds a fuse and AA battery. The banana jack is very thin and you screw it in. The meter looks like new and the probe if as it is never used. Not a scratch on it.
Even the text is flawless.
I have no clue about the specs but it is really spot on. That is upto 10A, because that is the max current my calibrator can source. Very impressive and still a very usable instrument.
