When the OK key is clicked, the data table will fill, and the new curve will by plotted.
Delete
The currently displayed curve will be deleted from the database.
Note:
Aspirate, Dispense, and Target Method functions can use the curve data. When curve
data is used, the pump is commanded to move in steps, not by volume. The number of
steps to move the pump is calculated as follows:
Exact Match:
diffvol = requestedvol - measuredvol
xx= (diffvol * stepsperul)/1000.0
yy= (requestedvol * stepsperul)/1000.0
steps= yy + xx
The above data is "Micro Logged" as:
CalX: Vol: 10.0, Data: Req = 10.0 Meas = 7.7590, VDiff: 2.2410, SDiff: 35, Steps: Req
= 160 Act = 195
Interpolated Volume:
calvol = (requestedvol - measuredlow)/(measuredhi - measuredlow) * (requestedhi -
requestedlow) + requestedlow steps = (calvol * stepsperul) /1000.0
The above data is "Micro Logged" as:
CalI: Vol: 135.0, Data: ReqL: 125.0 MeasL: 125.8600 ReqH: 200.0 MeasH:
207.5100, CalVol: 133.39559094, Steps: 2134 = 133395.59094 * 16) / 1000.0
