3.4.2. Set-Up Waste Streams:
The following parameters must be set for each waste stream to be used:
WASTE STREAM PARAMETERS
Waste I.D. Alarm Message
Count Time Clean Message
Count Display Maximum Weight
MCA Data Efficiency
Alarm Type 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
