500g x 0.01g High Precision Digital Scale SF-400D2 Counting wit USB Wall Adapter 855011003294 | eBay
That's the one I ordered, but I don't think it comes with weights.
I have a SF-400D. But I believe that the Calibration process is the Same as for the SF-400D2.
Here is what you do...
Place the Scale on a Solid, Flat Surface.
Make sure the Scale can't rock. Adjust the Feet if it does.
Check the Level of Scale by looking Straight Down on the Level Bubble. Once again. adjust the feet until the Bubble is in the Center of the Bubble Window.
Plug in the Scale using the USB Cord/Wall Wart.
Set the Scale to Grams using the Mode Button.
Hit the TARE Button so the Scale reads 0.00
To Calibrate the scale, Press the CAL Button one time. The Scale will now say "CAL".
Press the CAL Button one more time and the Scale will Blink "CAL" two times and then Blink "200g".
Place a 200g Standard on the Center of the Scale.
After a second or two it will Blink "500g"
Remove the 200g Standard and put a 500g Standard on the Scale.
After about 2 Seconds the Screen displays some Weird pattern like the countdown timer on the Aliens wrist in the Schwarzenegger movie predator. Then it displays "500.00g".
The Calibration is now Complete.

Be sure to Wipe Off any Weight Standard you used with a Clean Cloth or Paper Towel. And then the Standard set somewhere you can Easily find it. And not in the Back of some Obscure Drawer like I did.
