What is motion tolerance for, when using the HI 3010?

On the HI 3010, motion tolerance detects if the scale is dispensing or filling. If the scale is filling or dispensing it is considered to be in-motion, meaning the weight is changing more than the motion tolerance in a one second time frame. This could also be attributed to scale problems appearing as a slow or erratic weight change.  (example: bad load cell, water inside the load cell cable or summing junction box, or wind blowing on the vessel, etc.).

An in-motion condition will prohibit start, discharge, tare, print, zero, and aux device functions.  The aux device function is enabled when there is the lack of motion at discharge.

Correct motion tolerance levels ensure you will tare and zero the scale at the same level every time.

A base motion tolerance level is calculated by multiplying 0.03% times the load sensor capacity.  A smaller tolerance can be selected for tighter control.  (100 lb times 0.0003= motion tolerance of 0.03lb)

At the end or start of a process, the ON cycle or discharge will not proceed until the scale is out of motion.  A minimum of one second is required to compare two weight readings to determine motion or not. If the motion control is too tight, the controller will be slow to exit an in-motion condition. This will cause unnecessary delays in your process.  A "wait" message will be displayed until the motion tolerance level is met.  The scale must be out of motion before the final weight is declared during an operation.  Making the motion tolerance too large and the process will start or stop before the scale has settled from the previous condition.
