Type K1 (1908, 1909) Previous
The K-1 was a refinement of the K with some modifications of the windings and magnetic circuits to reduce internal losses.
The rotor was changed to add a removable lower pivot and a brass nameplate was used on the case instead of cast lettering on the K's case.
Both the low-torque and high-torque versions were introduced in 1908.
The K series of meters were available with 2 different terminal arrangements - under the main cover or in a separate compartment.
