Setting Contaminant-Detection
Parameters
This section assumes you have followed all the instructions from the start of the “Setting
Up Gravity-Feed Applications” to this point. The reason for this is that, before you can
calibrate your detector, the parameters described above must already have been set.
This section tells you how to do the following.
• Set up a monitoring baseline for the detector by calibrating the X and R noise
thresholds, which must be done when no product is present in the duct.
• Select the appropriate value for the speed filter.
• Establish basic product parameters (detect level and phase-angle).
Once you have finished this section, your detector will be set up and ready to go to work
monitoring your product stream for the presence of metallic contaminants.
Establishing a Baseline with No Product Present
Before you can establish a monitoring baseline (that is, establish a background-noise
level) for the X and R thresholds (the parameters that allow the detector to identify
metal contaminants), you must make sure no product is falling through the duct.
