WARNING
Any unauthorized attempt to repair or modify the product, or any other cause of damage beyond the range of the
intended use, including damage by fire, lightning, or other hazard, voids liability of the manufacturer.
Activate this product only if sensor, visual, detection, and audible cover are clear from contaminants such as dirt and
debris that could block the area where gas is to be detected.
Do not clean and rub the LCD screen of the products with a dry cloth or hands in hazardous environment to prevent static
electricity.
Perform cleaning and maintenance of the products in fresh air that is free of hazardous gases.
Test the response of the sensor regularly with a gas concentration exceeding the alarm set point.
Test LED, audio, and vibration manually.
Gas concentration measurements by the sensor can vary based on the environment (temperature, pressure and
humidity). Therefore, calibration of PM
400
should be performed in the same (or similar) environment of the device’s actual
use.
If the temperature changes sharply during use of the device (e.g., indoors vs outdoors), the value of the measured gas
concentration can suddenly change. Please use the PM
400
after the gas concentration value has stabilized.
Severe vibration or shock to the device may cause a sudden reading change. Please use PM
400
after the value of gas
concentration has stabilized. Excessive shock to PM
400
can cause the device and/or sensor to malfunction.
Alarm values are set based on the alarm standard that are required by international standards. Therefore, alarm values
should be changed only under the responsibility and approval of the administration of the work site where the instrument
is used.
Use IR communications in the safety zone which is free of hazardous gases.
Do not attempt to replace the battery and sensor as PM
400
is designed to be disposable. Changing the battery and sensor
may impair intrinsic safety and the attempt will void warranty.
CAUTIONS
Before operating this device, please read the manual carefully.
This device is not a measurement device, but a gas detector.
If calibration and self-test fails continuously, please do not use the device.
For the O2 detector, perform calibration every 30 days in the fresh air environment.
Before use, please check the activation date, and if the activation date has passed, please do not use the device.
Clean detectors with a soft cloth and do not use chemical substances for cleaning.
To maintain a 24-month lifetime, avoid the below activities except in necessary cases to check events (Max/Min),
lifetime/concentration, and alarm set points. Otherwise, the frequent use of the button will deplete the battery lifetime
less than 24 months.
1.
Push the button frequently without valid reasons.
2.
Frequent alarm operation or alarms are remained for a long time.
*Normal Alarm Use: 1 time and 2 minutes per day.
3.
Connect with the PM Link frequently except the bump testing.
View a serial number on the label at the back side of the device. (ex, 20170101)
