I don't have to worry about the power going out any more because I moved. I still use mechanical tools to do everything but tumble. I have always had a generator and when the power was out I dragged it around so the neighbors could keep their freezers frozen. (that's just what neighbors do)
I trust my balance beam scales and I can calibrate them and check the calibration against my lab scale that gets professionally calibrated every year. The point I was making was that I find it hard to trust the electronic scales since the few that I have tried didn't work out well. That was a few years ago and the more expensive scales are probably adequate but, like I said, "maybe I'm old fashioned or a bit nostalgic..."
I am not going to tell you not to use your electronic scale - just that I prefer my beam scales.
I am pretty much a stick in the mud for new things but when I got the first electronic scale it was like being liberated.
While I still keep the old balance beams I don't even bother to use them for cross check. Between the cal weight and the pan cross check I have seen no need.
I won't tell anyone that a beam is worthless, its not, it works.
I have gotten fond of fuel injection and not having to set the choke on the engine and pump fuel pedal a few times though. Pretty much the same thing.
Just a side note: Our whole neighborhood pulled together, it was the people who did not come ask for help that lost stuff.
One guy next door went out and bought a big generator and powered up himself and two other neighbors. That was generous of them, ours was barely enough to power up our stuff. We did check the adjacent ones and they were ok, if not we could have rotated them in and out.
By the time it was into it two days I had the utility disconnected and back powered the whole house.
Interesting the only thing that caused issues was the garbage disposal. That is a power hog. left it off and good.
We were the second longest without. They could not figure out where I feed came from. We had a friend that took 10 days to get back.
Our area they finally jumped across a main street with a wire and got it going.
Then they called in an outside electrical company, something like 12 rigs working the neighborhood to find it (they finally did).
One neighbor was on his generator for 3 weeks as his service entry wires and meter got ripped off and not an electrician to be had in town of course.
