- Page 5 SIZE control to be positioned somewhere near its midrange, rather than at either extreme of its adjustment. Note the the full-scale output of the BPM-832 is +/-1.999V. This is also the full-scale range of the digital panel meter (1999 units). To get the maximum resolution, adjust the gain controls so as to give a maximum expected reading of close to 2V.
- Page 6 BPM-832 Instruction Manual 4.5 FILTER The low-pass filters built into the BPM-832 allow the user to attenuate unwanted high-frequency noise or artifacts which may be present on the pressure signal. The filter cutoff frequency should be selected to limit the signal to frequencies of interest.
