How do I select a good REC parameter on my Hardy Process Solutions rate controller?

Should I use a zero or a tare command?

When should I use a zero command, as opposed to a tare command? Why should I use one instead of the other?

Can you explain the parameters for the HI 1756WS?

Why is the AuditTrail link missing on Operation>Diagnostics page of my HI 4050?

Why is the link to the Audit Trail sometimes missing from the Operation>Diagnostics page in my HI 4050 browser? If I check my SD card with a card reader I can find the Audit Trail file along with the Parameters file. If I make changes to the parameters file, or load an older, previously saved file, onto the SD card, the Audit Trail link goes away on the Diagnostics page. Later I find that it has come back. Why is this intermittent?

What accuracy can I expect on my belt weighing system?

We have a system using 3 load cells (total capacity 675 lbs) and a Hardy Process Solutions weight controller to measure weight and rate on our feed conveyor. The material feed rate continuously varies from 1000 pounds per hour to 10,000 pounds per hour. The speed of the conveyor is fixed at 80 feet per minute +/- 3%. At the end of the day they totalize, via the PLC, the amount fed. It seems accuracy is around 10%. What accuracy can we expect, assuming our programming is correct? Can you offer suggestions to optimize that?
