need help calibrating the JPrecision 10 scale

[beezaa]

so todays the day guys, SWIM just got everything together for SWIMS first initial dose of 2c-i and any physcadelic for that matter. SWIM's problem is that when he puts on the 10g calibration weight it shows around 9.998-9.995
im wondering how to calibrate it to 10g exactly or will it always be a little off??

I am not personally familiar with this scale. This is one of the cheapest models available, correct? If so, I'd expect a drift of a few mg from this scale no matter what you do.

There should be a button to press for calibration. On some scales the power button is also for calibration, and on others there is a specific button for such. One presses the button, gets some sort of signal from the readout, and places the calibration weight on the weighing pan. The scale should calibrate itself so that it reads exactly 10.000g with the weight.

Didn't the scale come with directions?
