It should, of course, be simple: You step on it, it displays your weight.
Except mine has a habit of displaying the same exact weight for days on end. I don't know if it's a physical problem, or (more likely) remarkably stupid software, but it appears it will read out the same value, as long as you're within a few pounds of that value.
So, as I've finally figured out, the correct sequence is:
- Move the scale where I can use it
- Step on it lightly, to start its zeroing sequence
- Grab something heavy, step on the scale
- Wait for the measurement to stabilize
- Step off the scale, put the heavy item back down
- Wait for another zeroing sequence to finish
- Step on the scale again
- Wait for the measurement to stabilize
- Record measurement
Of course, I still don't know if it's showing the correct weight - the box claimed it was "accurate" because it displayed to within 0.2 pounds. It didn't mention if it actually measured to within 0.2 pounds...
In related news, I seem to be finally weighing reliably under 230 pounds. In fact, it read just over 227 yesterday - but after dessert at Chevy's, the gallon jug of tonic water last night, and
Eh. I'm just happy I'm down to looking only 8 months pregnant.
