Hi, I just bought a used Index 2, which looks to be in excellent condition. I was able to set it all up and add me and my wife as users no problem. Did a weigh-in and got all the data through.
The problem is that it is consistently low on weights, around 7% low. I tested it with some 3kg weights we have (2 at once) and it weighed it at 5.60kg. Our old scale weighs them at 6.00kg. This 7% difference holds true for my weight too and my wife's.
I've tried doing the tare and it stays around the same.
Anything that can be done about this? I can't seem to find anything online, just help on how to tare it (done that about 10 times!!).
It also takes a LONG time to settle on a weight, jumping around as much as 3-4kgs as it does... is that normal?
