Alarm Level

A detailed description of each parameter entry follows:

Waste I.D.:

This parameter provides a description of the waste stream. The operator may program up to 16 alpha-numeric characters to provide a unique reference for each waste stream. The existing I.D. will be displayed.

Count Time:

Scan time, in seconds. Enter a value between 1 and 50,000, or "0" for minimum count time. If minimum count time is selected, the system will automatically calculate the minimum time required to scan the item. The following are assumed for automatic scan time calculation:

bkg = background in counts/second

consig = confidence sigma (fixed at 1.65Õ or 95%) fasig = false alarm sigma (fixed at 2.33Õ or 1/100) alev = alarm level in cps/efficiency

efficiency = waste stream efficiency
