I have a 650. When resetting the powder drop for a new cartridge, I do this.
Fill the hopper at least 1/2 full. Raise the platform up, with a small paper cup (Dixie cup) under the funnel. I then hand-jack the powder bar 10 times. Empty the cup. Jack it 10 more times, & measure on the electronic scale. Now divide the powder weight by 10 to get your average drop weight.
Adjust the powder bar & repeat the process. Repeat process till you are averaging the weight you are looking for.
I have found this gives me the most consistant powder drops when reloading.
& empty that hopper when you are done for the day!
