Can't say for sure, but most likely, it will read the current weight, but not a negative weight. The company web sight has FAQ's and contact numbers. You should be able to ask them directly.

Not necessarily. If the test line is not as dark or darker than the control line then it is neg. Not bother trying to analyze negative tests.

No, this produces no negative voltage. The "-" terminal is marked to indicate what you would normally refer to as DC ground

No. They are each numbered differently. There are two dots above each number and a line beneath each number.

Not that I know of. There isn't any notation on the box. You should contact the manufacturer, I would hate for someone for have an reaction. Take good care.

No, but there is a "reverse mirror" function on the top that will reverse the negative. This enables you to continue to slide the negatives through.

It's 18/0 and that's a good thing. That second number indicates amount of nickel, and nickel is very toxic. I don't want any nickel in my set.

No, and all numbers are digitally displayed. I love it! It goes by "hard or soft crack" stage, alas well.

I bought this for my granddaughter, so I'm not sure if the numbers were included or not. 'Wish I could help. Good luck.

Yes it does but I would look for another calculator. I have had two and they have both been terrible. This one after the first week just hangs up and won't add the last number unless I bounce it on the desk. Looking for something better myself.

If I remember correctly some things like the pH show a range & others just show positive or negative.

There is a negative tray with it. You would have to have them in small slices to do so I do not think it is practical. You slide the one negative at a time in. The size of negative of a slide negative.

It sounds like the positive and negative are reversed. I use it on my dog and she definately reacts to the negative. I have learned that you can't be too far from your dog/dogs or the alarm will not have any effect on them. Hope this helps you.

No. It reads to whole numbers, like 106, 285, etc. It has a wide range, even reading up to 900 and over.

There is NO "positive" and "negative" in house wiring. Please do a web search on "lamp re-wiring". An improperly wired lamp can give you a bad shock (or worse) even with the switch off.
