11-5. External Output Signal
11-5-1. Near zero [pin 17]
When weight value
≦
Near Zero set value, the Near Zero output turns ON.
The weight value could be Gross, Net, Absolute Gross, Net or Comparison OFF that are selected in
Near Zero Comparison of the Comparison Mode.
11-5-2. Lower limit, Upper limit [pin 43, 44]
The Lower Limit output turns on when weight value < Lower Limit set value.
The Upper Limit output turns on when weight value > Upper Limit set value.
The weight value here could be Gross or Net that are selected in U/L Limit Comparison;
Also, could select Comparison regularly, or Comparing when external judging input is on (EXT.
JUDGING ON) in the U/L Limit Comp. Mode of the Comparison Mode.
* When Total is selected in U/L Limit Comparison, the setting value of Upper/Lower Limit is increased

Under Weight value < FINAL set value - UNDER set value
Over Weight value > FINAL set value + OVER set value
Go FINAL set value + OVER set value
≧
weight value
≧
FINAL set value - UNDER set value
The weight value depends on the setting of OVER/UNDER COMPARISON.
11-5-7. Complete [pin 24]
After data sampling, processing of average calculation is executed.
After processing of average calculation, the COMPLETE signal turns ON.
