1. Introduction
If this product is to be unused for an extended period of time, the
battery level must be checked periodically (monthly). Replace the
batteries if the battery level is low. Failure to do so may cause them
to leak, which will lead to product failure.
This product is an intrinsically safe device (combustible gas sensor
employs a flameproof enclosure). Do not disassemble, modify, or
alter the structure of this unit or its electrical circuits. Doing so may
impair the performance of the explosion-proof characteristics.
Do not leave the product in high temperature and/or high humidity
conditions for a long period of time. Doing so may impair the
performance of the product.
Avoid using the product outside the specified operating
temperature/humidity range. Also avoid exposing the product to
abrupt temperature/humidity changes. Failure to do so may impair
the performance of the product.
Avoid rapid changes in pressure. Failure to do so may impair the
sensor performance or damage the sensors.
Avoid strong mechanical shock, impact or vibration to the product
by dropping or bumping. Failure to do so may impair the
performance of the product.
If condensation is present on the product, remove it and make sure
the unit is completely dry and checked for abnormalities before use.
This detector may detect gases or solvent vapors that are not target
gases. Keep the environment you are using the detector in into
consideration.
Do not use the product in a place or near a place where silicone
sealant/vapor may be present. Doing so may compromise the
performance of the product.
Detecting high concentrations of sulfur dioxide or chlorine may
shorten the sensor life or increase errors.
Because the oxygen sensor has pressure dependence. Make
necessary pressure adjustments when using the detector at a place
other than sea-level, such as at high altitude.
Keep the detector away from wireless devices while in use. Failure
to do so may cause a false alarm or fluctuations in the reading due
to radio wave interference.
The gas sensors contain harmful substances. For disposal, return
them to New Cosmos or treat them as industrial waste.
This product can be considered drip-proof when in its carry case.
However, exposure to water splash is not recommended.
