• If an abnormal response is received, check if there are any errors such as
transmission data errors. Correct such errors, if any. If an error occurs
regardless of the absence of mistakes, it may be a temporal phenomenon
caused by noise or other external reasons or the external host device may
have a system error. Turn the sensor head or system turned OFF and ON.
