Hmmm, looks like I snoozed on reading thru that.  S---, sorry all, thought I

| Hiya Bruce,
|      I'm not sure what the 34-150 hz is supposed to be....maybe a
filtering
| value?????  but from C69E-C6E6 is the transfer function from volts to
grams
| per second....btw most frequency types go much higher..like 10,000 or
12000
| hz...hth's
