Notes:

(1)

1 Oe (Oersted) = 1 Gauss in air = 0.1 millitesla = 79.8 A/m.

(2)

Limited by FTDI USB driver availability and computing device USB port hardware

(3)

Resolution can be increased in software by oversampling.

Nominal ADC resolution is 16 bits.

Effective resolution at high speed is lower.

(4)

Limited by ADC to <250 Hz, which may be achieved in binary mode.

Binary mode should not be used in Normal Sampling Mode.
