I put the StickC on the desk and make sure it will not be moved and be steady.<br />
Then I tried the codes below but got the acceleration higher than "1g".  Why is that?</p>
<pre><code>&gt;&gt;&gt; from hardware import sh200q
&gt;&gt;&gt; import math
&gt;&gt;&gt; imu = sh200q.Sh200q()
&gt;&gt;&gt;
&gt;&gt;&gt; for i in range(5):
...     print((imu.acceleration[0],imu.acceleration[1],imu.acceleration[2]))
...     wait(1)
...
...
...
(0.138, 0.058, 1.107)
(0.14, 0.055, 1.111)
(0.139, 0.058, 1.111)
(0.138, 0.055, 1.11)
(0.136, 0.06, 1.11)
&gt;&gt;&gt; for i in range(5):
...     print(math.sqrt(imu.acceleration[0]**2+imu.acceleration[1]**2+imu.acceleration[2]**2))
...     wait(1)

Is there a special calibration method?<br />
Thanks....</p>

<p dir="auto">but it is 11% more than 1g.<br />
Is it normal?  I suppose the tolerance is much lower than 10%.</p>
