•
•
•

In the event of an alarm, immediately take all necessary
treatment to prevent gas poisoning.
Do not block the gas sensor opening in use.
In case liquid spill from the sensor element is happened(by mechanical shock etc.), immediately wash clothes inwater when liquid is adhered.
In case of getting liquid in eyes or ears, immediately
submit to medical treatment after receiving ﬁrst aid bywater.
Be sure to execute daily check and periodic check.
Do not disassemble or modify XS-2200 because it could
cause to lose explosion-proof design.
Use the product in compliance with applicable laws andregulations.

Avoid storing the product or leaving it for a long period oftime in places or car subject to high temperatures andhigh humidity or low temperatures and low humidity.
Do not use the product at outside the operating
temperature/humidity range, and under rapid
temperature/humidity change. It may aﬀect the functions.
Keep the product away from exposure to water orcondensation.
In case of condensation, dry completely before using the
product.
Wear the detector where audible, visible and vibration
alarm can be noticed easily.
Only use speciﬁed battery (Panasonic alkaline AAA
battery LR03X or Toshiba alkaline AAA battery LR03).
The use of unspeciﬁed battery may impair the detectorʼs
explosion-proof performance and product performance.

―4 ―（ ）Safety pin adaptor (C-10) installation procedure

Installing the safety pin adaptor onto the battery lid allows wearing of the device
with the safety pin.Follow the installation procedure described below:①Install the safety pin adaptor on therear surface of the product bodychassis using the binding screws.

②Bend the safety pin adaptor frombelow and install it on the battery
lid using the tapping screws.

３．Operational Procedure① Turning the power on
ON
OFF
PEAK

Press and hold the [Power (PEAK)] switch forapprox.3 seconds. “on” will be displayed,
a countdown will begin with “3,” “2,” and “1”,the gas alarm settings will be displayed, and then air adjustment
will be automatically performed. Upon the completion of air adjust-ment, the measured gas concentration will be displayed.
Make sure to turn on the power in clean air. Since air adjustment

WARNING will be conducted automatically, the incorrect gas concentrations
will be displayed when turned on in gas atmosphere.

Note

After switch operation, the LCD display light (backlight)
turns on for approx. 5 seconds and then turns oﬀ automatically.

W A R NING

② Gas detection (Alarm status)

The above-recommended cycle is only an estimatebased on normal use and proper maintenance without
exposure to high concentration gas or gas poisoning;
therefore, no guarantee is provided.

Press and hold the [Air Adjustment] switch for approximately

ADJ.

Execute the air adjustment again in clean air. If thealarm is activated after multiple adjustments, request
repairs.

Be sure to execute the air adjustment in clean air.
Accurate gas detection results cannot be obtained if theadjustment is made in an atmosphere mixed with gases.
Execute the air adjustment at least once a day. In
addition,make the air adjustment when the work
environment（temperature or humidity）changes
because the 0ppm setting value may drift.

Readout error.
Remove and reinsert the battery. Turn on the detector tocheck performance. If normal operation cannot be
restored with this procedure, request repairs.

Press the [Power (PEAK)] switch to display PEAK.
The highest concentration value marked
during PEAK being displayed will remain
displayed. To reset the value and return to thenormal screen, press the switch again.

The H 2 S sensor may be incorrectly installed.
Check the sensor. Request repairs, if ”Err.S”
displayed even though the sensor is correctly
installed.

isIf the operation switches or displays do not operate properly other than whenalarms are activated as described above, remove and reinsert the battery into
the product. Turn on the detector to check performance. If normal operation
cannot be restored with this procedure, request repairs.

（Alarm sound）

This product is a precision instrument. Please perform the periodical checks andinspections below to maintain the detectorʼs performance and ensure safety.
In the event of a failure to follow the safety precautions (page 2), such as impact shockfrom dropping or exposure to water, or use in conditions outside the speciﬁcations(page 13), such as usage in temperature/humidity exceeding the speciﬁed range,
please contact New Cosmos or your New Cosmos representative for inspection.
A comprehensive description of the current situation would be appreciated when you
contact us.

Note

When inserting the battery,match the polarities(+ and -) with the battery marks.
If the battery polarity is reversed,the detector
cannot be turned on and a continuous
vibration may occur depending on the battery
type.Remove the battery promptly and insert itagain with the correct polarity.

This product uses a very small amount of current evenafter turned oﬀ, to stabilize the sensor.Keep thebattery in the product even when the product is not being used.
If the battery is removed from the product for a long period of time,
initial stabilization of the sensor may take longer, causing an error. In
such a case,insert the battery and leave the product with the power
being oﬀ for one day or longer before use.

― 10 ―

Alarm activation and use at low temperature may
shorten the battery life.

④ Gas sensor opening
Check that the gas sensor opening is not blocked and the ﬁlter element isclean and dry. Replace the element if dirty or wet.

（2） Periodec Check
Check the product accuracy at least once a month and perform gas calibration
at least once every 6 months. It is recommended to contact New Cosmos or
your New Cosmos representative to perform a periodic inspection including
sensor replacement at least once a year (fees apply).

8． Glossary

7． Speciﬁcations

The peak value memory function can provide the elapsed timeback to 99 hours 59 minutes ago. Beyond 100 hours, “100H” and“OL” will be alternately displayed in the sub screen and the elapsed
time will not be displayed. The time error is±5%.

Pressing the [Air Adjustment] switch while the detector is oﬀ
can display the last peak value. However, turning on thedetector will reset the peak value to 0ppm.

Note― 11 ―

Reading accuracy *1

Remove the two screws and remove the battery lid.
Replace the battery with a new one.

Execute daily check in clean air before use.
① Operation
Check alarm sound, alarm lamp,vibration and LCD work properly when
the detector is turned on. If not ,request repairs.
② Alarm function
Check the alarm indications such as alarm sound, alarm lamp andvibration by having the detector draw gas at a level that slightly
exceeds the alarm level.
In the event of an abnormality in the way the gas concentration
readings change , such as the alarm lamp does not ﬂicker or the buzzer
does not sound, request repairs.
③ Remaining battery level
Check the remaining battery level of the gas detector.
If the remaining battery level is low,replace the battery.
(See “4. Replaceing Battery ” on page 10)(See “Replacement Parts” on page 5)６．Maintenance―7 ―The recommended replacement cycle for sensors is
one year. Replace the sensor with a new one annually
to ensure correct detection.
