to enter. Then enter the
filter menu again and selected the appropriate filter weight.
Filter weight is the level of baseline noise filtration. OFF indi-
cates no filtration. 10 is maximum filtration. In most cases, select
BFT for baseline filtering. The FLT setting applies a RC filter to
the entire signal. For high-speed chromatography, less than a 5
sec peak width, select BFT and turn the weight OFF. If the peak
widths are 5 to 30 seconds use the BFT filter with a weight of 1 to
10. For peak widths greater than 30 seconds, select the FLT
setting with a weight of 1 to 10. When the baseline filter is on, a
dramatic operation condition change (e.g. turning on/off attached
equipment), may upset the filter and cause baseline drifting. The
baseline will stabilize again in a few minutes.
