Application Notes for Production Rate Mode
1. Choose an averaging time, in seconds, you want to use for computing your production
rate.
For example if you want to average over 45 minutes, your averaging time will be 2700
seconds.
We need to calculate an update time for your display, we will have up to 200 samples avail-
able in your averaging period.
Update time = 2700/200 = 13.5
Round this up to the nearest whole number.
This is set in the variable
bin.t = 14
Set
bin.cnt = 200
This means that your display will update every 14 seconds in this case.
NB If your averaging time is less than 3 minutes, please use the formula:
Update time = averaging time/20 , round up to nearest whole number =
bin.t
Set
bin.cnt
= 20
2. We now need to set a scale factor so that your display reads correctly in items per hour,
per minute or per second.
The scale factor settings will be....
For items per second =
SCALE
= 1/bin.t
For items per minute =
SCALE
= 60/bin.t
For items per hour
=
SCALE
= 3600/bin.t
For items per shift
=
SCALE
= 28800/bin.t
For items per day
=
SCALE
= 86400/bin.t
