• Note: The long press function only works in detection mode. When changing or resetting any data, remember to click the ON/OFF button to confirm and save the settings. Turn on the pump when starting the detection and turn off the pump when not in use to prolong its service life.

Power On / Off:
To power on/off the device, long press the ON/OFF button for 3 seconds.

Zero Calibration:
Note: Zero calibration of oxygen detector, nitrogen detector, and carbon dioxide detector (target gases that are components of the air) cannot be done in the air. Only target point calibration (setting the value of target point concentration as the standard concentration values in clean air) can be done.

Process of Over-range incorrect operation:

1. Air Inlet
2. Air Outlet
3. Air chamber of sensor
4. LCD
5. PLUS
6. MINUS
7. MENU
8. ESC
9. ON/OFF

Note:

• If the detector is used for gas cylinder detection, use a pressure regulator to handle the high pressure. Set the flow rate to 800mL~1L/minute and the pressure to 0.1MPa or 1Bar.
• After measurement, place the detector in clean air for about 5 minutes and wait for the data to fall down to normal before turning it off.

Operation Interface

The operation interface displays the alarm status, alarm setting, low battery alarm, and restore setting options.

Alarm Status:
When the detected gas concentration exceeds the low alarm value, the alarm sound will be activated, and the yellow light will flicker. When the gas concentration exceeds the high alarm value, the alarm sound will be activated, and the red light will flicker.

Alarm Setting:
To set the alarm values, press the MENU button, choose the Alarm point set, and start setting the low and high alarm values. Use the PLUS or MINUS buttons to change the values. After setting, press the ON/OFF button to save the settings.

Low Battery Alarm:
When the battery is low, there will be sound and light low battery alarms. The device will emit sound and light every 5 seconds to remind the user to charge it in time. When the battery is completely drained, the device will turn off automatically.

Restore Setting:
If all settings are incorrect or if there are operational errors, you can restore the detector to factory settings. However, if the detector is working normally, avoid using this setting. To restore the detector, a password is required. Please contact the supplier for assistance.

Storage Set:
In the storage setting, you can set the storage status and the interval for data recording. By default, the storage status is OFF, so you need to set it to record data. Press the MENU button, choose the Storage set, move the cursor to ENABLE, and use the MINUS button to change NO to YES. The storage interval can be set from 5 seconds to 1 hour.

Keys Operation

(Note: The long press function only work in detection mode. When you change or reset any data, please remember to click “ON/OFF” button to confirm and save the settings. Remember to turn on the pump when start the detection. Please turn off the pump when there is no need to detect, which will be helpful for the service life of the pump)

Power On / Off

• Put the detector in clean air, and press the “ON/OFF” for three seconds, the detector will be turned on and the pump will start to work. The screen displays the following interface successively: Brand and Logo, main parameter interface, initialing countdown. The countdown would be 60 or 120 seconds, which is to make sure that the sensors are fully activated. After countdown, the device enter normal detection interface.
• Take the detector out of the detected environment and wait for the data to get down to zero, then press the “ON/ OFF” to turn off the detector

Zero Calibration

• Zero calibration must be done in clean air. Better to do once after alarming happens.
• Press ”MENU” to enter parameter setting mode, select the “calibrate zero”, and press “ON/OFF” to enter the mode.
• Observe the value of “real time concentration”. If the reading is not zero and the drifting is too big when the reading is stable, then it is necessary to conduct zero point calibration.
• Press “ON/OFF”, the real-time concentration will go back to zero, and press ”ESC” to go back to detection mode, gas concentration values also back to zero.
  Note: Zero calibration of oxygen detector, nitrogen detector and carbon dioxide detector (target gases are component of the air) can not be done in the air. Only the target point calibration (value of target point concentration is the standard concentration values in the clean air) can be done.

Process of Over-range incorrect operation

Users should avoid using gases which exceed the measure range to impact the sensor, because it will affect the lifespan and sensitivity of the sensor, even, “poison” the sensor. If there is any over-range incorrect operation makes the detector displaying an concentration at a large reading, the remedy is to take the device out of theenvironment immediately and put it in clean air for over half an hour, and then observe the reading, if it keeps going down, then wait until the reading back to zero before powering it off, and do the zero point calibration next time before using it. If the reading maintained at full scale, user should send the device back to manufacturer or agent for repair or replacing the sensor.

Operation Interface

When the detector is turned on completely, the device will enter the detecting interface. The gas type will be showed on the top left, and the time and battery power will be at the right. In the middle, there is the real- time concentration. If the detector is with data storage function, there will be the storage status at the top of the concentration: ON or OFF, and the total storage number. There will be BEEP-ON at the bottom left, which means the alarm is on. The PUMP-ON at the bottom right, which means the pump is working.

Alarm Status

• When the detected gas concentration is higher than the low alarm value, the alarm sound will be on, yellow light will be flickered.
• When the detected gas concentration is high than the high alarm value, the alarm sound will be on, red light will be flickered.

Alarm Setting

• Press “Menu”, choose the “Alarm point set”, and start to set the alarm value.
• There are LOW POINT and HIGH POINT for set, press “MENU” to move the cursor to the value you want to set, and press the “PLUS” or “MINUS” to change the value. After the setting is done, press “ON/OFF” button to save the settings.

Low Battery Alarm

When the battery is low, there will be sound, light low battery alarm. There will be sound and light every 5 seconds to remind the user to charge the device in time. When the battery is used up, the device will be turned off automatically.

Restore Setting

When all the settings are wrong, or users operate the detector in a wrong way, you can restore the detector to factory settings. But if the detector works normally, please don’t operate this setting. In order to avoid wrong setting, password is needed. If you want to restore the detector to factory setting, please contact the supplier.

Storage set

• In the storage setting, you can set the storage status and the interval. Every time you turn on the detector, the storage status defaults OFF, so you need to set the storage status if you want to record the data.
• Press MENU, choose the “Storage set”, move the cursor by pressing MENU at the “ENABLE”, press MINUS to change NO to YES.
• The storage interval can be 5 seconds, 10 seconds, 15 seconds, etc. The highest interval is 1 hour.

View history data

• Press the MENU, choose “view history data”. Then at the top is the record total number, and the reminder “PLEASE SELECT”. Now, if you press MINUS, then the record data will be from the first record to the second in turn.
• If the record number is above 10, and you want to check the specific number, you press the MENU again, then you can input the exact number and check that record(press the MENU to move the cursor, and press the MINUS and PLUS to change the number), press ON/OFF to confirm and then you will see the detailed record.
• In the detailed record interface, at the top are the record total number and current number. In the middle are the date and time, and the concentration is at the bottom.

To make sure the detector work perfectly and you can check the history data quickly, we suggest you to erase the history data regularly. Press MENU, choose the “Erase ex_flash”, password is needed (the password is 9999), then press ON/OFF, it shows that “erasing”, and when finished, it will turn back to the detecting interface.

Target Point Calibration

Note: Calibration needs to be done by professionals and with necessary accessories and standard gas.

• Prepare the standard gas before starting the target point calibration. In detection mode, press ”MENU”, select “calibrate span”, press ON/OFF button to enter. Then you will need to enter password. (If you need password, please contact the manufacturer to get it)
• After entering the password successfully, press ON/OFF to enter the target point calibration interface, as shown in the picture. The interface will display “concentration”, “set value. The concentration is the result got from the calculation of several internal calibration parameters. The process of calibration is the process to recalculate the internal parameters of the device. The set value is the value need to be entered manually; it should be the concentration of the standard gas to be calibrated. Select the parameter under the current interface, modify its value with “PLUS” and “MINUS” button.
• The calibration process is as below:
  1. Connect the detector with standard gas cylinder by hose.
  2. Enter the target point calibration interface, set the “SET value” as the standard gas concentration.
  3. Release the standard gas to the detector in a flow rate of 500mL/min. The value of “concentration” will become larger gradually, and become stable after 30seconds.
  4. When the value of “concentration” is stable, press the “ON/OFF” button, the value of “concentration” will be same with or almost same with the “Set value”. The calibration is finished.
  5. Cut off the standard gas supply. Press “ESC” to go back to detection interface.
