Metering Test Screen
This screen is useful in both R & D and development purposes when testing the metering performance of each feeder. The user can perform a “Single Meter by Weight” to evaluate the mechanical standard deviation of the gate or auger. This test meters for the calculated time based off the target weight entered on this screen. The blender does not retry or adjust the time of the meter to reach the target, but instead always meters for the same amount of time as long as the target weight has not been changed. This allows you to open the gate for several feeds using the same amount of time. You can then record the Dispensed Grams and plot the standard deviation of the gate. The other purpose of this screen is to verify that the dispensed weight displayed is correct. You can perform a meter and then pull the weigh hopper to weigh the material on a gram scale. The value on the screen should match the measurement on the gram scale. If it does not, then either the weigh hopper is not balanced correctly or the scale calibration is not correct. Refer to the Troubleshooting Section of this manual for additional details.

Advanced Weight Options Screen
This screen allows you to modify the weight filter, adjust the mechanical time to settle the weigh hopper after dumping, adjust the mechanical time to settle after a feeder has introduced material into the weigh hopper, adjust the Maximum Empty Weight of the hopper, and to enable the batch weight data to be dumped to a printer every batch for diagnostic purposes. The data that is dumped to a printer is the same data shown on the Recipe Screen. No averaging is done with the data shown to the Customer. Targets vs. Actual are actually what is in the batch without any “smoke and mirrors.”
The weight filter is the specialized filter algorithm that smoothes erroneous load cell readings. The signal will be filtered more if this value is increased and less if decreased.
