Rated 4 out of
Very good overallThis load cell is accurate and the user friendly free software interface with the USB is easy to use. The load cell is very heavy and feels very durable, but the thin diaphragm between the center and ring has already been ripped through by relatively light use. Load cell still operates fine, but it would be nice if the durability of this area could be improved.
how can these load cell be used in dasylab? I was not able to find any information about communication protocol. Can anyone help?

SAE, let me a little bit more specific. the software available in the USBH.zip file has a glitch. when used together with a platinum display, the time synchronisation is going very badly. Basically it records more data points for the USBH unit that for the platinum, although both are selected at same sampling rate. this is very anoying.
