OPERATING PRINCIPLE: Self-oscillating split-beam Cesium Vapor (non-radioactive) OPERATING RANGE: 20000 to 100000 nT OPERATING ZONES: The earth’s field vector should be at an angle greater than 6° from the sensor’s equator and greater than 6° away from the sensor’s long axis. Automatic hemisphere switching. CM-221 COUNTER SENSITIVITY: <0.004 nT/ pHz rms. Typically 0.02 nT P-P at a 0.1 second sample rate or 0.002 nT at 1 second sample rate. Up to 10 samples per second HEADING ERROR: ±1 nT (over entire 360° spin and tumble) ABSOLUTE ACCURACY: <3 nT throughout range OUTPUT: RS-232 at 9600 Baud |
