Figure 5-1: Data Format

For UNIPOLAR ranges: For Unipolar ranges, data are in true binary form.

0000 0000 0000 0000 = ZERO

1000 0000 0000 0000 = 1/2 SCALE

1111 1111 1111 1111 = FULL SCALE

For BIPOLAR ranges: For Bipolar ranges, data are in complementary offset binary form.

0000 0000 0000 0000 = + FULL SCALE

1000 0000 0000 0000 = ZERO

1111 1111 1111 1111 = - FULL SCALE
