dears,
i have a requirement to make a checkweigher that will work at 270 ppm
conveyor speed is 1.36 m/s 
product length is 40 mm
conveyor length is 300 mm
gap between products is 300 mm
product weight is 207 grams
i need to reach an accuracy of ± 0.9 grams from the actual weight of the sample 
is this achievable using the Siwarex WP351 HF module i have
because when i tried the quick guide in the manual 
i can't reach a good accuracy with this linear speed 
what are your recommendations for my setup.
thanks in advance

Hello

could you give me some more data of the scale/application:

• Belt length: 300mm
• Belt speed: 1.36m/s
• Length of the longest product: 40mm
• Dead load(construction on the load cell):
• No. and nominal of the load cell(s):

Attached you find a little guide for the setup of a dynamic check-weigher.

If you have done this procedure and still issues you can do a trace of several weighing and send it together with a backup of the parameters.
Some photos of the scale could also help.
How to do a trace, you find in the second post that I will send next.

If you don't want to make these data public you might open a support requesthttps://sieportal.siemens.com/en-de/mysieportal/support-requests/create
or write a mail to hotline.siwarex@siemens.com. 

Be aware, a dynamic check-weigher with Siwarex WP351 is not legal for trade.
