Unique simple way to measure current
Measuring current in electronic circuits could not be simpler. Just like the clip-on ammeters used by high current electricians, all you do is clip the jaws around a wire, up to ~3.5 mm diamter, and get the DC current in ranges from 1 mA to 10 A FSD.
And it is surprisingly accurate: on my test, within 1% FSD. The zero setting on the lowest range (1 mA FSD) does drift a bit (~0.05 mA) due to probe wear and the Earth's magnetic field.
Despite mine being about 60 years old and having all original parts, it still works like new. It uses a number of industrial grade vacuum tubes, so if any fail, it might be difficult to find replacements. Suitable electrolytics would be impossible to find, as would the concentric coarse/fine pot.

Typical Japanese quality
I bought this to complete a museum quality collection of accessories. Third party or hand-made alternatives would be better value if you want it for routine measurements

Good product from a great seller
As this is an engineering test record for objectively evaluating a replay system, one must to a certain extent put it on trust. It is something that is good to have on hand for when testing a new system is required.
What made it extra good value is that the seller included a second record at no extra charge.
