CAUTION
•
Remove the battery for long term storage to avoid any possible
damage to the Multi-gas Detector due to the battery leakage.
•
XA-4400II is an intrinsically safe Multi-gas Detector. Do not
attempt to disassemble, remodel, modify of structure or circuit,
etc., as it may affect the performance.
•
Keep the Multi-gas Detector away from heat and moisture as it
may affect the performance.
•
Do not use in the condition out of the operating temperature,
humidity or pressure range and avoid sudden change of
temperature or humidity, as it may affect the performance.
•
Avoid rapid changes in pressure, as it may affect the sensor
performance or it may cause damage to the product.
•
Do not drop or hit the Multi-gas detector to avoid mechanical
impact and strong vibration, as it may affect the performance.
•
If the Multi-gas Detector is dropped or hit and the reading
fluctuates, allow enough time to stabilize the reading before use.
•
In case of condensation, dry the Multi-gas Detector completely
and check the performance before use.
•
Use the Multi-gas Detector in suitable environment to avoid
detection of other interference gas or solvent vapor.
•
Do not use the Multi-gas Detector in an atmosphere containing
silicone gas or silicone products, as it may affect the performance.
•
Detecting high concentration of sulfur dioxide or chlorine may
decrease sensor life or increase errors.
•
Detecting hydrogen sulfide for a long period of time may decrease
sensor life or the sensor sensitivity.
•
Make the pressure correction when detecting gas at places where
the atmospheric pressure is different from the standard, such as
high altitude places, due to the pressure dependence of oxygen
sensor.
•
The gas sensor contains toxic substances. When disposing of the
sensor, return to New Cosmos Electric or treat it as industrial
waste.
•
Low temperature may shorten the battery life due to the battery
property.
•
Keep wireless devices away from the Multi-gas Detector while in
use, as it may cause fluctuation in the reading or may cause
alarm errors due to radio waves.
•
The vibration alarm may be difficult to notice depending on the
wearing position.
