Question: Can I trickle a powder charge and have the scale display the weight change in real time, or do you have to add, remove, reweigh?
Document: Accurate and easy to use. I found that after trickling in additional powder to come up to the desired charge, it may take a second or two to register on the scale. Accordingly, if I add some more powder, I wait a couple seconds before adding any more so I don't exceed my desired weight. I use the scale on a very firm table,away from heating vents in the room, and plugged in to the AC adapter.
I followed the instructions for first time use. After that, I tested it with various units of known weight and it was perfect. So, what more could I ask for? I would recommend this scale to my friends.
The large digital display is easy to read and it's simple to use. The instructions say to leave it turned on for 24 hours before using it for the first time and if not used for about a month or more. I thought that was a kind of a strange requirement. Other than that, it works fine.
This sure beats using the standard scales. I used to measure my powder charges using two beam scales to verify the charge. I now trust the accuracy of the Lyman Micro Touch 1500 Electronic Scale 115V 7750700.
Works very well and is very accurate with a couple of provisos. Leave it on all the time and dont use it where a heater or cooler draft will blow across the scale while in use. reading will fluctuate with the airflow over it. Also do not move the scale from the position you calibrated in once you start measuring. Otherwise compares dead on with a very expensive balance beam scale I used to use. Love the backlit big digit display. Highly recommend.
Not a jewelers scale by any stretch.....especially in price. Does what it needs to and does it fairly well. Weighs the same charge to the same weight repeatedly.
I like this scale for my purposes of checking charge weights from my RL-550B when loading handgun cartridges. As a best practice, I calibrate the powder measure and continually throw and weigh charges on the Lyman until I've got the correct charge for what I'm going to be shooting.
Love this little guy. I was skeptical my last digital scale was all over the place and was accurate above 10grains or .5 grams anything below that sucked. Bought this little guy for pistol 10mm auto. I hand weigh every charge close to max levels and this scale is fantastic. My last scale would shutt off quickly and had to be recallibrated each time it was turned on. This little sucker stays callibrated and is ready to go till u turn it off.
I bought this scale and was disappointed that I could not get the unit to calibrate after several attempts. I followed the instructions to the letter but this scale could not be calibrated to show a repeatable calibrated weight. I also had a problem with the on off button on this unit. I sent it back and although this was the first time I had to ever return anything through Amazon, I am very pleased with the way that they handled this return.
Very nice scale. I replaced a malfunctioning AWS scale with this. The touch screen operates well, and the backlight it great in low light conditions. The scale measures quickly and very accurately. The included powder tray and calibrating weight makes this all you need to measure powder accurately.Only downside is the scale flip cover is too small to accomodate the powder tray, so you have to leave it sitting behind or next to it.
Answer: Yes, I was able to add powder gradually to the scale and it displayed the gradual increase. I did not have to add and remove the powder cup.
