So … the annual trip to the witch doctor to bless the unit isn't actually necessary?
The internet has lied to me again.

I would say no...but I have grown horns and a tail since getting the CM. I'm not sure that's a problem. Yet.
My Gen 6 mentions a 15min warm up.
I believe the electronics have an acceptible operating range. Any fluctuation within that range would be insignificant.
Also, I think some take the line AC voltage and change it to a regulated DC operating voltage.
If your public electric generator is known for spikes, that could be a killer and should be protected againist.
Gen 6 on right.

I do turn mine on for 15-20 minutes before setting zero.

After 3 fingers of fine single malt, the internet is quite believable…
I use one, but probably not like most people. I found it to be less precise than I desired so I measure out each load 0.3 grains light and trickle in the rest on a beam scale. I've seen my velocity ES and SDs come down quite a bit. I also verify the accuracy of the beam scale every so often with reference weights. Once you have a rhythm it doesn't add much time at all.
For non-critical stuff like bulk, short-range stuff I still use it.
Before I changed, I pulled some bullets and measured the charges. There was a powder variation of up to 0.3 grains. As for a warm-up period…… we're not using vacuum tubes. I don't think a little power fluctuation will matter much either, but that's just my general gestalt from my engineering days. I think microfriction from sitting a while is probably more important than an electronic "warm-up."

In concurrence I will reply in the affirmative; yes bwana!
Re Power spikes & drops- I have a dedicated line for all my reloading equipment.

I have an old Chargemaster. Its power comes from a 12 VDC power converter. I don't see how a power conditioner would improve that situation. I leave mine plugged in and turned on all the time.

I have had a chargemaster 1500 for the last decade or more. I let it warm up for 15 to 30 minutes if I remember. Lately I have been doing a lot of single stage loading and dump a charge out of my uniflow and trickle the charge up to weight while on the chargemaster.
This has been done at all times of the day and night. I have noticed a lot of - weight shift while the pan is off the scale and another charge is being thrown. At first this concerned me as I had rarely observed this when I used the chargemaster to throw the charge.
I got out my RCBS 1010 beam scale to verify charge weights and found they were right on target no matter what the chargemaster said when the pan was off the 1500. Check weight were used to verify and the chargemaster was calibrated at the beginning and a few times during long sessions.

I have only had my Chargemaster Link for a few months. I let it warm up for 30 min and have it plugged into a UPS I got for $10 from a business going under and liquidating there equipment. Have not had any issues.

I have the Chargemaster 1500 and must say, anyone who thinks electical current fluctuations don't affect motor speeds or sensative equipment like electronic scales either needs a refresher course in basic sciences or admit they do not care about precision and with all due respect, leave the discussion to those that do.
For those people that are only using their Chargemaster to get their obviously rough loads to the nearest whole grain, this discussion of the finer things in life clearly isn't for you (pun intended)
For those people that believe electrical instruments like digital calipers are accurate to the last digit displayed, you may want to rethink that. The last digit on the display needs to be ignored as the software is either rounding up or rounding down to that number. The rounding varies from manufactures and the traditional understanding of rounding is not necessary at play.
I am not an electrical engineer but as a watchmaker I can, with 100% certainty, tell you fluctuations in electrical current affect electrical instruments. Lathe spindle speeds will vary, degrading the precision of the cut. Clocks wired to the municipal current (stoves, school clocks, etc) are worse than a bucket of water with a hole in it like a Chinese water clock simply due to the fact that AC current is not a constant 60hz here in the USA. Of course this standard varies around the world. Clocks in cars are much more precise instruments yet equally piles of crap because they do not have temperature copensation and to the measurement drifts by 5-10 whole minutes a year.
As for warming up your scale, this definitely makes a difference in accuracy and consistency. Some ultra precise electronic watches running on batteries even have built in temperature compensation to keep the rate accurate because each of the electrical components inside will behave differently as temp changes. For equipment plugged into 120/220 the current will do quite a bit of warming up compared to the 1.55v or 3v inside a watch. Load tests and current consumptions reading on watches will vary quite a bit between the testing machine warmed up, freshly turned on but plugged in and freshly plugged in.
Long story short, cleaning up your power will actually increase the accuracy and consistency of your equipment. Universal Power Supplies are great for isolating your equipment from the fluctuations caused by other draws in the home/business. Ferrite line filters are are great too. I have noticed more consistent throws with my UPS unplugged running soley on battery backup.

CHARGEMASTER 1500 Best Results and Practices
I've read through a lot of posts on the Chargemaster 1500, different practices, and ways to get the best results, but I didn't feel like there was one good place where all the tricks I use were shared so I wanted to condense them into a single thread. To start, the Chargemaster 1500 is a lot of...

How accurate is RCBS Chargemaster 1500?
Get 3 or 4 of them going and your reloading experience will be a) just as rewarding and b) 10x faster. I use three and can barely keep up. Four would be excessive.
