[QUOTE="Rum River, post: 2918189, member: 16869"] For years I've been using the RCBS powder metering system where the Powder Pro scale and the metering are two separate units. It still works so I'm happy. A couple weeks back I screwed up and got the two power supplys mixed up. Didn't damage anything but was getting an 'Err1' message when calibrating the scale. Until then I didn't know there was a way to do a 'factory calibration'. Once I went through all those steps everything works again - and now I make sure I keep the power supply correct! I plug my scale in for at least 15-20 minutes to warm up, watch out for drafts, etc. ***One other thing to remember is that the LCD readout on the scale takes time to respond. On my system the motor will stop dispensing powder but the scale still reads light - I have to wait maybe 3 seconds for the scale to catch up.*** If you're taking the pan off an LCD-readout scale immediately after the motor stops there's a chance you don't have the powder charge you think you have. For those interested, below are the steps to do the factory calibration. I know lots of shooters on this forum have much newer equipment, but you never know. Tedious steps, but I can say it worked out perfect for me. ************************************************************************************* If you have the Powder Pro Powder Scale: 1. Remove the Scale Pan from the Platen 2. The scale must be turned off. (If the "On/Off" button does not work, unplug the scale and depress each of the four buttons five times.
