Model 2755 measures resistances from 1 Ω to 10 MΩ by operation of dials and switches. Batteries and a galvanometer are self-contained. The front control panel is provided with power and galvanometer circuit selectors, one ratio arm, and four measuring dials.
Model 2755 is also equipped with a Murray and Varley Loop Tester for convenient location of line faults such as "shorts" and "grounds" in power, telephone, telegraph, and signal cables.
No auxiliary attachment required
