Sartorius Scale quarterly calibration - standard weights

We use a Sartorius Scale (LA120s) to calibrate laboratory pipettes.  We have a third party calibrate the scale on an annual basis.  If you have a scale you use to calibrate pipettes or weigh out chemicals, would you be willing to share your policy/form for the quarterly calibration?

We have weights the lab uses to perform the quarterly calibration.  However, we need to purchase new standard weights.  I'm a Blood Banker that has never been responsible for this aspect of the Scale.  Need guidance to make sure we are in compliance with the CAP COM.30880.  I believe they need to be Class 2 weights.  I'm curious at what measurement range we should have on site.  Original policy was written in 2003 and doesn't look like it has been updated since. 

Thanks - any information will be appreciated.
