I have a problem about calibration. Total nominal weight capacity is 2000 kg for 4 loadcells. (2 mv/V) I connected them to Siwarex CS with 4 wire connection. I communicate with CS by Siemens blocks and Siwatool CS. I used 150 kg as adjustment weight instead of 5% of nominal weight which is 100 kg. When I calibrated I saw the value 2.3 kg instead of 150 kg. Also I checked status section in Siwatool CS that the system has been calibrated. My calibration parameters are below: Adj. Digits 0 : 0 Adj. Digits 1: 60000 Adj Weight: 10000 Min Weight: 0 Weight Range: 2000 I transferred some parameters to flash memory by accident. What should I do? What is the solution for calibration? Thanks a lot.
	Regards,

In you adjustment parameters I see the digits 0 at 0 and digits 1 at 60000. This are the default values, so you might have done an mistake during the calibration. As adjustment weight you have set 10000, this is wrong. Here you have to set the value that corresponds to your calibration weight. e.g. 15000 if you have 150kg calibration weight and 2 decimals. !!! With this weight resolution you can only measure up to 327.67kg, because the weight value is an 16bit integer !!! If you want to measure more weight you have to reduce the decimals e.g. to 1, the you have to change the adjustment weight to 1500. The calibration procedure is as follow: 1. Set adjustment weight and send it to the Siwarex CS 2. Remove weight from the scale and execute the command “adjustment zero valid (3) 3. Load the adjustment weight to the scale and execute the command “adjustment weight 1 valid (4)". 4. Receive the adjustment data DR3 to save the new adjustment digits. The complete adjustment procedure you find in the QuickGuide http://support.automation.siemens.com/WW/view/en/37733418 Regards ABenno
