The Frequency Ranges allow the user to specify one or two discrete frequency ranges for inclusion into

lower and upper corner frequencies. Weight factors are also available to allow an imbalanced ratio of
signal energy to be included from two ranges if desired. A single range is adequate to produce the low-

Additionally, two frequency ranges can be used to do combinations of low-pass, high-pass, and band-

requires this option.

The incoming detector head signal may be tuned in 1 or 2 ranges. The ranges cover from 12Hz to
1024HZ. The system defaults to 1 range. If 2 ranges are chosen, adjust them both, upper and lower
ends, but NO overlapping of frequencies is allowed.

Press F1 - CHG then type “2” (to change from 1 range to 2 ranges)

Because the IDD signal is monitored from the A/D converter output for the purpose of setting the GAIN,

GAIN setting will need to be rechecked.
