1. Introduction
Thank you for purchasing the Multi-gas Detector XA-4000II series. Be sure to read this
instruction manual and use the product properly to prevent gas accidents and for
inspection and maintenance.
This Multi-gas Detector measures up to 2 to 4 gases of oxygen (O2), combustible gas
(COMB), hydrogen sulfide (H2S) and carbon monoxide (CO), and it displays all gas
concentration values at the same time. This Multi-gas Detector gives a notification with
an alarm to help to prevent gas accidents, such as lack of oxygen, gas explosion or gas
poisoning, when the gas concentration exceeds the alarm set value.
Read and understand thoroughly this manual regardless of your experience with using
gas detector. Do not use this Multi-gas Detector for improper purposes. Do not use the
Multi-gas Detector in undocumented way in this manual.
Waterproof
Be sure to keep the gas sampling port dry.
This Multi-gas Detector employs a water proof structure which meets
our tests* complying with JIS C 0902-2003 Ingress Protection code
IPX7 at brand-new condition to prevent malfunctions due to water
from unavoidable circumstances in use. However, if the filter element
is wet, the gas cannot be detected properly. Since the age-related
deterioration of packing or label, or adhesion of foreign materials
degrade the performance of water proof structure, exposure to water
should be avoided as much as possible.
* Immerse the new Multi-gas Detector gently from the bottom into
the depth of 1m from the surface of standing tap water at room
temperature and verify that there is no damage from ingress of
water after 30 minutes.

Safe Operation
Be sure to observe the following to use the product safely and properly.
DANGER When the gas alarm is sounded, take all necessary precautions
immediately to avoid explosion.
•Be sure to turn ON the Multi-gas Detector in normal condition
(clean air). Since the AIR adjustment starts automatically, the
erroneous gas concentration will be displayed in gas atmosphere.
•This Multi-gas Detector is a safety product. Perform daily check
before use (see “Daily Check” on page 33).
•Do not close the sampling port or exhaust port. The gas cannot be
detected properly.
•Do not block the buzzer port or the alarm will be hard to hear.
•Use clean filter elements. If the filter element is dirty or wet, the
gas cannot be detected properly.
•The sensor unit is guaranteed for two years from the date of
purchase. It is highly recommended to replace a sensor after two
years for proper gas detection.
•Be sure to use the specified battery. The product will not meet the
intrinsically safe requirements without the specified battery (see
“Battery Replacement” on page 28).

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.

<Gas Concentration Display>
WARNING •Do not block the detection port as it cannot detect gases.
•Keep the filter element dry and clean. If the filter element
becomes dirty or wet, it may affect the detection performance.
•Keep the gas detection port dry from rain or water when
wearing the Multi-gas Detector.
•When the reading exceeds full scale, move the Multi-gas
Detector to the clean air immediately, as it may become slow to
return to the base or it may affect the detection performance.
•Careful not to block the buzzer port as the alarm volume may
be too small to notice.
For button operation, a “press” is less than one second, and “press and hold”
is about three seconds.
NOTE
CAUTION •A significant change in temperature or humidity at work
environment may affect the concentration values of 21.0vol%,
0%LEL and 0ppm. In this case, press and hold the [ AIR
ADJ.] button to start “AIR Adjustment (Zero Adjustment)” (page
14) in the clean air.
•Blinking “0” or “0.0” of gas concentration
indicates negative value. In this case, high
concentration gas may have been detected,
or AIR Adjustment may have been performed
in gas atmosphere.
Perform “AIR Adjustment (Zero Adjustment)” (page 14) in the
clean air. If [E-S] is displayed (page 27), turn OFF and ON the
power in the clean air.
•The vibration alarm may be difficult to notice depending on the

(methane), hydrogen sulfide, and carbon monoxide.
1. Turn ON the Power -> Warm-up -> Displays <Gas Concentration Display>
Press and hold the [ POWER] button to switch into <Gas Type Display>.
After a beep, all segments are displayed on the LCD, “ON” appears, and the countdown
starts: 3, 2, 1. Release the button after a bleep.
Then <Gas Type Display>, <Full Scale>, <AL1 Alarm Set Value>, <AL2 Alarm Set
Value>, <TWA Alarm Set Value>, <STEL Alarm Set Value> and <Time/Temperature>
will be displayed automatically. After <Air Adjustment> and the warm-up operation is
completed, it switches into <Gas Concentration Display> after three beep sounds.
•The warm-up operation will take about a maximum of 2 minutes.
•Only the power OFF button is available while the warm-up operation.
•In case of an error occurs, see “Error Messages” on page 27.
Make sure to turn ON the power in the clean air. Since the air
adjustment starts automatically, the erroneous gas concentration
will be displayed in gas atmosphere.

<Gas Concentration Display>
WARNING •Do not block the detection port as it cannot detect gases.
•Keep the filter element dry and clean. If the filter element
becomes dirty or wet, it may affect the detection performance.
•Keep the gas detection port dry from rain or water when
wearing the Multi-gas Detector.
•When the reading exceeds full scale, move the Multi-gas
Detector to the clean air immediately, as it may become slow to
return to the base or it may affect the detection performance.
•Careful not to block the buzzer port as the alarm volume may
be too small to notice.
For button operation, a “press” is less than one second, and “press and hold”

concentration display for 3 seconds. When the AIR Adjustment (ZERO adjustment) is
completed, [21.0vol%], [0%LEL] and [0ppm] will be displayed.
3-3-2. Peak Hold Function
1) In normal operation, press both [ POWER] and [ AIR ADJ.] buttons at the
same time.
--> A beep will sound once, PEAK will be displayed in the bottom of the LCD, and it
starts updating the current peak value (maximum value; minimum value for
oxygen).
2) To cancel the Peak Hold Function, press both [ POWER] and [ AIR ADJ.]
buttons at the same time again.
--> A beep will sound once, PEAK will be off, the peak value will be reset, and it will
revert to the normal <Gas Concentration Display> (instantaneous value).
Make sure to perform AIR Adjustment (ZERO Adjustment) in the
clean air. The erroneous gas concentration will be displayed in
gas atmosphere.
