The Minolta Auto Meter Professional and Auto Meter II are calculator dial exposure meters. They look very similar to most other meters but the calculator dial is unique. With a press of the measure button the calculator dial rotates automatically.
The Auto Meter III was the first fully electronic version with LCD display and measurement-result memory.
The Auto Meter series was succeeded in 1983 by the Minolta Auto Meter F series which extended functionality of the Auto Meters to flash exposure measuring.
