Are there clear directions for calibration? What weights would I need to calibrate the scale? I hope to weigh fractions of a gram.

Scales come already factory calibrated. To recalibrate it, press and hold MODE key. LCD flashes 'CAL' and then '200.00'.* Place 200 g standard calibration weight, wait 3-4 seconds till LCD displays 'PASS' and '200.00'. Put away calibration weight, press ON/OFF key to turn off the scale. The calibration is finished. *NOTE. We supply currently scales that require 200g standard calibration weight.

Does the scale have an auto off feature? If so can it be disabled?

It depends on power supply. If powered by USB or AC/DC adapter, it does not have auto off feature. If powered by batteries, it has an auto off feature and con not be disabled.

What do you do if it does not pass calibation?

First time use: remove the protective pads under the weighing pan and the protective film on it. If loading weight is not stable or you abort calibration, the scale will show ‘Err’ and automatically turns off.

Great value, accurate, no "drift" to the strain guage. Works well with batteries or via a wall adapter. Versatile and inexpensive. I am using it for perfume making, and so need something accurate to .1 gram. Look no further.

It doesn't look as sleek as other small scales out there - it looks like an old school lab scale. BUT, you can plug it into an outlet (or use batteries if you want that) and you actually see the numbers on the scale very well even with a large mixing bowl on top. Great bang-to-buck factor when making soaps, cosmetics, etc. at home.
