Safety Information
Please read the following information before using the detector:
Do not use a damaged gas detector. Before using the detector. Check for cracks or missing parts. If the
detector is damaged or incomplete, please contact IMR.
It is highly recommend to do a "bump test" to ensure proper performance of the detector (refer to section
4.3 for more information). Calibrate the device if the test value is beyond detection range (refer to
section 4.8 for more information).
Do "bump tests" periodically to confirm sensor is responding to gas. Verify that the audio, visual, and
vibration alarms are working properly during the test.
Use only accessories specially designed for EX610 or accessories approved by IMR.
Use only the charger supplied with the detector. Do not charge the detector in hazardous area.
Detectors with catalytic or semiconductor sensor: Exposing the sensor to gas concentrations beyond its
detection range for a prolonged period of time can adversely affect the cell and possibly lead to damage.
Detectors with catalytic or semiconductor sensor: Will be damaged if exposed to environments
containing: lean chromate, sulfur compounds, phosphorus compounds, or silicon. Do not use the
detector in these environments.
Do not expose the device to environments that consist of hydrogen sulfide, halogenated hydrocarbon, or
highly corrosive gases for extended periods of time. Doing so will reduce the response of the sensor and
there for its accuracy. If the device needs to be used in environments preform a Bump Test before and
after to ensure functionality of the sensors (see section 4.3).
Do not expose the device to environments that have the potential for electric shock, strong magnetic
fields, or intense continuous mechanic vibration.
This device uses a lithium-ion battery. Follow all local environmental and governmental regulations
when disposing of the battery.
Any unauthorized disassembly, modification or repair of the gas detector will void the warranty.
Avoid dropping the detector from high elevations or exposing it to extreme vibrations.
For any issues not covered in this manual. Contact IMR for more information.

4.7 Zero Point Adjustment
If the device in the clean air and is not zeroing then follow the steps below to adjust the zero point.
In detection mode hold both and for more than 1 second until the configuration screen is displayed.
Status
Display
When holding both and the display will show this screen. After 1 second it
will then enter the configuration menu.
Once this screen is seen the configuration menu has been accessed. Press cycle
through the available options.
When the zero point is being set this screen will be displayed. The Zero calibration
process will complete in 5s and then it will return to detection mode.
Note: Zero Point Adjustment must be done in the clean air. Otherwise the accuracy will be affected.
Oxygen detectors use a concentration of 20.9％VOL in fresh air for the above process.
4.8 Calibration and alarm adjustment
If the detector needs to be re-calibrated or the alarm level adjusted follow the below steps.
4.8.1 Calibration and Alarm Levels
With the device powered off hold both and for 3 seconds. The detector then self-tests then after a short
delay it will require the password. The following will be displayed:
Input the password to enter into calibration mode.
Note: Improper configuration of the settings in this menu can endanger the end user; take extreme care with the
information entered. The detector will power off automatically if there is no input within 5s after accessing the
password menu or the input password is incorrect. If the password is lost or forgotten contact IMR.

4.8.2 Warming Up
After inputting the password the device will start a countdown to warm up the gas sensor. The countdown time
will be different depending on the sensor (30s～90s).
Note: During this countdown can be pressed to skip the calibration procedure and enter into the Alarm
Level Setting (see sections 4.8.6, 4.8.7).
4.8.3 Zero Point Calibration
The detector will now display the current output form the sensor. A screen similar to below will be shown.
If there is no input within 1 minute the last displayed value will be set as the zero point. Next the device enters
into SPAN Calibration mode.
During this mode if is pressed the AD value will be displayed. Then can be pressed to return to the
display of the current gas concentration.
Note: During this countdown can be pressed to skip the calibration procedure and enter into the Alarm
Level Setting (see sections 4.8.6, 4.8.7).
Warning: This operation should be carried out in clean air.
Failure to do so will affect the accuracy of the detector. When advancing to the next mode an Ewill be
displayed if the air is not clean or the sensor is damaged. Move to another location for adjustment or replace the
sensor as needed.

4.8.4 SPAN Calibration Setup
In this mode the screen will display a set of flickering figures. Press or to modify these figures.
Then the Standard sample gas concentration recommended to calibrate the detector will be shown. See the
image below:
If there is no input is made within 10 minutes the detector will then display a Calibration Error and advance to
the Alarm Level Setting mode (see section 4.8.6 and 4.8.7).
If gas input is applied within 10 minutes the detector will use the figure shown on the display as the
concentration of the calibration gas. It will then enter into the SPAN Calibration mode.
Note: See Chart 1 in section 9 for the available adjustable range of the calibration gas concentration.
4.8.5 SPAN Calibration
The detector will display the currently detected concentration of gas from the sensor. See the image below:
Next fit the calibration cover to the detector and apply the calibration gas. If the calibration gas is detected
within 30 seconds the detector will start the automatic calibration process. The detector will make automatic
adjustments until it reached the optimal calibration point. It then saves this information and exits sensor
calibration.
Next the detector advances to L-alarm setup.
Note: In this mode avoid touching any buttons. Failure to do so will affect the accuracy of the detector.
If half of the SPAN calibration point is not reached within 30 seconds or the gas concentration is beyond the
maximum range of the sensor. An Eicon will be displayed. This indicates that the test gas is unusable for
calibration of this sensor or that the sensor is defective. Replace the gas or gas sensor.
O2 calibration will skip step 4.8.3. and 4.8.4.

5. Data Uploading (If Equipped)
Connect the detector to a PC with a USB cable. Then open the data software.
Note: This function will be available only if the product that was purchased is capable of communication with a
PC.
6. Using and Replacement of sensors
It is important to be aware of the life span of equipped sensors. When they are beyond their expected life they
should be replaced. Approximately every half year calibration should be checked for accuracy in order to ensure
safety of the end user.
Sensor replacement should only be done by IMR or an authorized repair center. Only authorized parts should be
used. Contact IMR if any additional information is needed.
