?Do not use ultrasonic cleaning. Failure to comply
with these instructions may result in product damage.
use isopropyl alcohol and dry the device thoroughly before use.
?Avoid cleaning the sensor; however, if it must be cleaned
however, the label ID is hard coded inside the sensor.
?Do not use III Tri-chloroethane, methylene chloride,
methyl pyrrolidone, or any oxidizing type acid such as formic acid.
Cap the ports or connect housing to the ports before cleaning
the sensor with alcohol. Using alcohol may remove the text on the sensor label;
