The North Atlantic 801-F3 is a precision panel meter for measuring angular position in synchro and resolver systems. It delivers 0.1° or 0.01° resolution with 0.2° or 0.03° accuracy across industrial and aerospace applications. The instrument accepts programmable line-to-line input voltages of 11.8 Vrms, 26 Vrms, or 90 Vrms and operates across 47 Hz to 1200 Hz. A Type II tracking servo loop enables zero lag tracking up to 180°/second, while transformer-isolated inputs and discrete component construction ensure signal integrity and field maintainability.
