Warning
Always keep the probe away from areas where flammable gas
is present.
Failure to do so may cause fire and/or explosion because the
air velocity sensor is heating.
Never touch the air velocity sensor.
Direct touch to the heated air velocity sensor could cause burn
injuries.
Touching to the air velocity sensor may also cause damage to
the sensor itself. Never touch the sensor.
Operate the instrument only on the specified supply voltage.
Failure to do so may cause electric shock, fire, or sensor
damage.
Caution
Do not use the instrument in areas where vaper is present.
Touching a water droplet to the air velocity sensor can affect
the amount of the heat dissipation. This may cause inaccurate
measurement and/or damage to the air velocity sensor.
This instrument is designed to be used in the clean air flow
without dusts and/or foreign substances.
Touching or hitting the air velocity sensor with a foreign
substance may cause damage to the sensor.
Dust and/or foreign substances adhered to the air velocity
sensor can hinder accurate measurement.
Do not apply any excessive force to the air velocity sensor.
If the air velocity sensor is deformed, not only maintaining the
accuracy is impossible but also the element may be broken.
