4 Notices for Use of Equipment
Do not use it in the environment below 0℃.
 All calibrations shall be performed by professional engineers. Users are not allowed to perform such
calibration by themselves.
 The transmission distance of MT400 is limited and should generally not exceed 3 rooms. If the walls
of the rooms are made of metal materials, it is better to install a data receiver host in each room;
 MT400 is not waterproof, so the equipment shall not directly contact with liquid water;
 MT400 is equipped with polymeric battery and shall be not allowed to contact the high temperature
environment to prevent battery damage.
 Be sure to remember that the high-concentration VOC gas (such as direct injection of alcohol) can be
used for testing VOC, for the high- concentration VOC gas will contaminate the sensor. It is
recommended to use an ordinary permanent marker for the test. Remove the cap of the marker and
place the marker next to the sensor for 30 seconds to check whether the data changes.
