SW stands for the actual sample weight and DW represents the delivered diluent weight.
When the dispensing cycle is completed, following displays are shown.
Remove the filled sample bag or container and initiate the next dispensing cycle.

Note: If you have more than one WGT FACTOR, store one WGT FACTOR in “ Edit 1” , e .g .
“9.00”, while a second WGT FACTOR is stored in “Edit 2”, e.g. “99.00”. Up to ten different
sets of parameters can be stored in “Edit 1” through “Edit 10”.
Note: The following may affect your accuracy, and should be considered:
1.
Parker suggests you use #24 tubing, and move the portion inside the pump 3-4 inches toward
the discharge side of the pump periodically to avoid wearing it out. As the
tubing becomes
worn, your dilutions may take longer, and you may get debris in the diluent.
#35 tubing can cause target weight overruns, and is generally considered to be too large for
this application.
2.
Sniffle Factor. This is a parameter that can be adjusted to minimize the drips that occur after
the dilution, thereby eliminating overruns. These procedures suggest an initial factor
of 0.3. If you are using a filter, this may need to be increased as the filter becomes plugged.
3.
Slow Factor and Pump Rate. These parameters can be optimized further depending upon
your specific application. Increasing the Slow Factor will help if your scale response time
is long, and decreasing the Pump Rate will help if the default of 80% is causing too much
backsplash that can’t be eliminated in some other manner. The settings cited work best
with a Mettler Toledo model scale.
