8.6.2. Auto
zero
Performs zero adjustment automatically when “Enable” is selected for “Auto Zero”.
When conditions of auto zero range, dead zone timer and monitoring timer are met while the conveyor is moving, the
mass values obtained during the averaging time are averaged. Using the average value as zero, zero adjustment is
performed automatically.

8.6.3.
Auto zero range
Enter the range to perform auto zero adjustment.
When “Enable” is selected for “Auto zero” and the average mass value during the averaging time is within the auto
zero range, auto zero adjustment is performed.
8.6.4.
Dead zone timer
Enter the duration to prohibit auto zero adjustment after auto zero adjustment.
8.6.5. Monitoring
timer
Enter the duration to prohibit auto zero adjustment after the product is cleared of the weighing conveyor.
This is to avoid auto zero adjustment while the timing of the product to be cleared of the weighing conveyor is
uncertain, for example, packed products, or while the checkweigher condition is unstable with vibrations left on the
conveyor or rejector movement.
8.6.6. Averaging
time
Enter the time to average the mass values obtained during the duration to be used for auto zero adjustment.
8.6.7. Dynamic
compensation
Makes compensation when the mass obtained when the conveyor is stopped is different from the mass obtained
when the conveyor is moving.
When “Enable” is selected for “Dynamic compensation”, the Dynamic Compensation mark
appears in the
Weighing screen and dynamic compensation will be performed.
8.6.8.
Dynamic compensation value
Enter the value to be used for dynamic compensation.
