Model D (ca. 1905 to ca.1911)	Back	Up	Next
The Model D was a special version of the Model A made for those who did not care for a high-priced meter or require a high-torque meter. This meter has two unique features: It has a carrying handle built into the top and the cover slides on from and is fastened on the bottom. Although this was a commutator-type meter, many of this model were marked, calibrated, and sold for use on AC circuits.	Electrical Meterman's Handbook
