| In 1928, the Type H meter was redesigned slightly to incorporate improvements to allow the meter to retain accuracy over a wider range of temperatures and loads. Also, the stator was changed to make the disk turn to the right as with all the other models on the market. Like the previous Type H meter, the HC meters came with either a metal or a glass cover, and later HC meters have a studless cover that attaches to the base with a pair of bayonets. |
