Your ME109 series net weigh has been programmed to run with sample product at regulated 115 VAC power. Increases or decreases in voltage will cause ratio metric speed changes.
Products that look the same may have slightly different flow characteristics.
If your product flows differently than tested product, you may be able to raise or lower the hopper gate to increase or decrease hopper/feeder flow without altering programmed speeds.
For flow control that cannot be achieved by #3 above (or if power is 50 HZ or ¹ 115 VAC), feeder speeds may need adjustment. If so, see paragraph (vi), “Quick Check Program Guide.”
To store any such changes in permanent memory, see paragraph (c) “Supervisor Codes.”
