+Description:
+		For voltage sensing hardware, there may be different time between
+		channel conversion and sample update. 'Integration time' is used to
+		specify the channel internal conversion time. And sample update
+		interval is equal to average sample count multiple integration time.
+		Unit as microsecond.
