UPDATE 12-4-24:
I repeated the shunt tests, and found that all four shunts were 'bang-on', giving current readings that were well within the specifications. I can only assume that there was a poor connection somewhere in my setup.

In this video, I describe the HeathBuilt EUW-18 Laboratory Meter, which is one of about 15 special 'factory built" pieces of laboratory and test equipment that the Heath company produced specifically for the college/university/technical school market, including the "Malmstadt-Enke Instrumentation Lab" set and the "Berkeley Physics Lab" set in the late 1960s and early 1970s.
This product is simply a 1mA 50 Ohm milliammeter in a metal case, although it also came with four resistor shunts to allow the meter to be used with 1.5mA, 5,A, 15mA and 50mA full scales.
Here, I talk about the product's history, its place in the overall HeathBuilt series, and I demonstrate it in operation. I also show my sub-project of recreating the original four shunts.
