I'm familiar with just the name - Ingenuity Trickler but don't know its specifics. It works with the Dandy but I imagine it could work with any trickler with a 3 volt DC motor depending on its current requirement.
It will start trickling after replacing the pan after a programmable delay from 2 to 8 seconds if the weight is between 0 and the target weight. Another option is you can select an amount from 1 to 9 grains short of target weight where it won't start trickling unless the weight exceeds that amount. In other words, if the target weight is 30 grains and you select 2 then it won't start trickling unless the weight is greater than 28 grains. Two uses I know of - replace empty pan, check zero or tare, remove pan dump charge and place on scale. The other purpose - if the powder dispenser is mounted on the top of the draft shield placing an empty pan won't cause trickling until after you dump the charge.
