The North Atlantic 8810-F12 is a synchro/resolver angle position indicator delivering 0.001° resolution and 0.004° accuracy across a 0–359.999° range. Built around a TRIG-LOGIC processor, it tracks angular position without velocity error up to 200°/second and accepts standard line-to-line input signals without pre-selection or pre-programming. The instrument features autoranging circuitry that displays applied input voltage on its front panel gas discharge display.
