1. Introduction
Thank you for purchasing the New Cosmos XP-3000II series portable gas detector. Prior to
use, please read this instruction manual carefully to ensure safe and reliable operation.
XP-3000II series has single-gas (1-gas) and two-gas (2-gas) models available. 1-gas
models measure one combustible gas or oxygen, while 2-gas models simultaneously
measure one combustible gas and oxygen. The detector simultaneously displays one or two
gas concentrations. When gas concentrations reach a preset level, the detector alerts the
user via audible and visual alarms, thus, helping prevent incidents such as low oxygen, gas
poisoning and explosion. This detector uses an intrinsically safe structure.
Carefully read this manual, regardless of your experience with gas detectors. Do not use the
detector for any purposes other than those intended or described in this manual.
Symbols Used in this Manual
This manual uses Danger, Warning, Caution and Note symbols to draw attention to
procedures, materials, methods, and processes, which require particular attention.
Indicates an imminently hazardous situation that can result in death
or serious injury.
Indicates a potentially hazardous situation that may result in death
or serious injury.
Indicates a hazardous situation that may result in minor injury or
property damage.
Provides information on product handling.
DANGER
WARNING
CAUTION
NOTE
Waterproof
Keep the gas detection ports dry.
This detector employs a waterproof structure, which meets the New
Cosmos-specified submersion test* compliant with IEC60529 ingress
protection code IPX7 in the new condition to prevent malfunctions due
to water entry during normal usage. However, if the filter element is
wet, proper gas detection is not possible. Gaskets or sealing
deteriorated by age, or adhesion of foreign materials will impair the
waterproof function; thus, exposure to water should be avoided as
much as possible.
*Submersion test procedure:
Submerge a brand new detector into room temperature tap water to
a depth of 1 meter for 30 minutes. Verify that water is not present
inside the detector.

Introduction
Safety Precautions
To ensure safe operation, follow the precautions below.
Only use this product in accordance with the applicable laws and regulations.
When a gas alarm is activated, immediately take all the necessary
measures to prevent accidents including gas explosion and oxygen
deficiency.
Oxygen-deficient air or toxic gas may be discharged from the gas
outlet. Do not inhale.
High concentration combustible gas may be discharged from the gas
outlet. Do not place the gas outlet near an ignition source.
DANGER
Turn on the gas detector in clean air. Zero adjustment (20.9%
adjustment for oxygen) is automatically done during the powering-up.
Ensure that the zero adjustment is done in clean air. Inaccurate gas
concentrations will be indicated if the zero adjustment is done in a
gas atmosphere.
Do not block any gas inlet and outlet. If blocked, normal detection is
not possible.
Avoid water intake. Water entering the gas sampling tube or gas
detector will impair proper gas detection, leading to product failure.
Do not block the audio opening. If blocked, the audible alarm will be
muffled.
Keep the filter element at the drain filter clean and dry. If the filter
element is dirty or wet, proper gas detection is not possible.
The recommended sensor replacement cycle is three years for
combustible gas sensor (two years for oxygen sensor). The sensor
may fail to provide accurate detection after three years (two years for
oxygen sensor), and should be replaced.
See “Annual Inspection” on page 45.
Only use specified batteries. Using batteries other than those
specified may impair the product’s explosion-proof performance.

Install the gas sampling tube’s probe
nozzle to the sampling tube holder as
shown in the right photo.
3-1-3. Shoulder strap installation
(1) Separate the sub-straps from each other by opening the carabiner.
(2) Attach each sub-strap to the detector by threading its
loop through the strap hole (2 places) located at the
bottom of the detector. *Attach the sub-straps while
the detector is installed in the elastomer case.
(3) Reassemble the sub-straps into the shoulder strap
by closing the carabiner. *The shoulder strap length
can be changed with its adjuster.
3-1-4. How to use the stand
Lift the stand up such that the detector can stand
alone on the desk, etc. The stand can be opened
up to 90.

Operation
3-2. Operating Procedure
1. Power on -> Warm-up -> HOME screen
Turn on the gas detector with the gas sampling tube (or optional
drain filter or cooling drain filter in case of XP-3380II-E) attached,
in clean air.
Zero adjustment (20.9% adjustment for oxygen) is automatically
done during the powering-up. Ensure that the zero adjustment is
done in clean air. Inaccurate gas concentrations will be indicated
if the zero adjustment is done in a gas atmosphere.
Do not use the gas detector without with the gas sampling tube
(or optional drain filter or cooling drain filter in case of XP-3380II-
E). Proper gas detection is not possible without it.
Even after the HOME screen is displayed, the reading for zero
may fluctuate or blink due to an ambient temperature change,
etc. For this reason, it is recommended to perform zero
adjustment before use.
For the XP-3340II model, the reading may fluctuate or blink due
to interfering gas which is present in the atmosphere (e.g., CO2),
but this is not a device failure.
CAUTION
Perform routine check prior to use (page 44).
If the detector is marked with both temperature classes T3 and
T4, before deploying the detector in a hazardous area, the user
shall check the battery type via the LCD, and ensure that, if
MiMh batteries are fitted, the detector is only used in areas
requiring temperature class T3.
Use of the detector in an atmosphere with greater than 21% of
oxygen will compromise the explosion-proof performance of this
detector.
Detector which is marked with temperature class T4 only, shall
only fitted with alkaline primary batteries.

Operation
Press and hold the power button until the power-on screen (company logo ) is
displayed on the LCD.
--> After the unit beeps once, the “model, serial No. and battery type”, “target gases”,
“full scale values”, “alarm set values”, “previous calibration date” and “log memory
usage”, and“Bluetooth not available”screens will be displayed in sequence. When
the unit gives off a beep, a warm-up cycle will start. The warm-up progress bar will be
displayed. When the warm-up cycle is completed, “Warm-up completed 100%” will be
displayed and a zero adjustment will be automatically started. When the zero
adjustment is completed, the unit will give a long beep and the gas concentrations
screen (HOME) will be displayed.

Operation
2. Detection
When the HOME screen is displayed, it means that
the detector is ready for use.
--> See “LCD” on page 10.
--> See “HOME Screen” on page 17.
--> See “Gas Alarm Operation” on page 18.
HOME
When the ○i icon (temperature/humidity change indicator) blinks or when “0” or
“0.0” for the gas concentration value blinks, perform zero adjustment in clean air.
See page 22.
The following situation may cause zero drift (0%LEL, 0ppm
or 20.9vol% point may drift). In this case, perform zero
adjustment in clean air (page 22):
zero adjustment was performed in a gas atmosphere,
a significant change in the work environment (e.g.,
temperature or humidity change) takes place, or
a high concentration gas was detected.
CAUTION
Do not block any gas inlet and outlet. If blocked, normal
detection is not possible.
Keep the filter element at the drain filter clean and dry. If
the filter element is dirty or wet, proper gas detection is not
possible.
If a reading exceeds the full scale value, move the detector
to clean air area immediately. If not moved to clean air and
continued to be used, improper gas detection will result, or
it may take time for the reading to return to the zero point.
Do not block the audio opening. If blocked, the audible
alarm will be muffled.
WARNING
During button operation, “press” means to press the button for
less than one second, and “press and hold” means to keep
pressing the button for more than two seconds.
