The Chargemaster dumps powder by weight. The dispenser has to communicate with the scale. The Chargemaster will dump powder at full speed, when the amount of powder is close to the desired weight the dispenser will slow down to a trickle and slowly finish the charge. If your scale is not part of the Chargmaster System then it will not be able to communicate. If one of your scales is a Chargemaster 1500 scale then it will work, if not then you are out of luck.
