The full scale deflection of the meter itself is a relatively tiny 50 ... mentioned use for finding current peaks and troughs in analogue circuits. The MF47 will stay on my bench as a much lighter ...

Analog multimeters use a needle indicator and scale to show readings, while digital multimeters (the dominant style today) show numeric readings on an LCD, LED, or other electronic display.

Analog dials used to be a pretty common way ... and it’s combined with a MF-110A multimeter. It’s super easy to buy that stuff and start tinkering with the concept yourself.
