<p class="MsoNormal"><span style="mso-fareast-language:EN-US">A resolution of 1 g and a reporting frequency of at least 20 per second can yield a 0.1 g reading over 10 seconds (200 readings at least). The Adam Scale below can give 175 readings per second so
over 10 seconds it is 1750 values. These are averaged (two options for how it is done) using Jeremy’s Digital Scale Capture programme. Provided you are not using a Chinese OS, it can display the readings, trends, mass burned and average kW in real time. It
also gives the 10 second mass change, and a 1 minute calculated firepower value. For those working in ‘difficult’ circumstances, it is important that it pretty much cannot lose data. The file is opened, added to, then close each 10 seconds. If the power goes
off all data captured to that point is retained.<o:p></o:p></span></p>

can manually drive scales that are not capable of being placed in a continuous transmit mode.

Dear Andrew<br>
<br>
? In the meanwhile I have one question about Xavier's list of equipment needed for his CSI test: did you really mean a 30kg scale with a resolution of one gram? ?<br>
<br>
The CSI is not ? my ? test. It is one of the alternative lab protocols to the WBT. I am not a scientist and don?t have a lab, I don?t perform the test. The CSI is, in my opinion, the most interesting because it has little in common with the WBT, so it avoids
to reproduce the WBT issues, and it is contextual. That is why I talk about this protocol the most.<br>
