⚠
WARNING
• Clip SGD is a hazardous area certified gas detector and as such must be operated and
maintained in strict accordance with the instructions, warnings and label information
included in the manual.
• Before operating this device, please read carefully and understand all instructions in the
manual.
• Understand the screen display and alarm warnings prior to use.
• Before use, please check the activation date, and if the activation date has expired please
do not use the device.
• Before use ensure that the device is in good condition and the enclosure, the display
window, alarm LED windows and sounder aperture are undamaged and clear from
contaminants.
• Before use perform the self-test of the LED's, sounder and vibrator.
• Bump test the device regularly by applying a gas concentration exceeding the alarm set
point. It is recommended that a bump test is performed at least every 90 days.
• For the O detector perform a calibration every 30 days in a fresh air environment.
2
• If the device fails a bump test, calibration or self-test please do not use the device.
• Do not disassemble or substitute components, or operate beyond the intended range
of use as this may impair intrinsic safety, invalidate safety certification and will void the
warranty.
• Do not attempt to replace the battery or sensor as the Clip SGD is designed to be
maintenance free and disposable. Changing the battery or sensor may impair intrinsic
safety, invalidate safety certification and will void the warranty.
• Use IR communications only in a safe area that is free from hazardous gases
• To prevent the generation of static electricity do not clean or rub the LCD screen of the
device with a dry cloth or hands in a hazardous area environment
• Perform cleaning and maintenance of the device in a safe area only that is free from
hazardous gases.
• The Clip SGD is shipped with default alarm level settings. It is the users responsibility to
ensure the alarm level settings are appropriate for the specific application; these can be
changed as required via the IR_ Link _PC Software.
• Gas concentration measurements by the sensor can vary based on the environment
(temperature, pressure and humidity). Therefore calibration of Clip SGD should be
performed in the same (or similar) environment of the device's actual use.
• Severe vibration or shock to the device may cause a sudden gas reading change. Please use
Clip SGD after the value of gas concentration has stabilized.
• Excessive shock to Clip SGD can cause the device and/or sensor to malfunction.
• If the temperature changes sharply during use of the device (for example moving from
indoors to outdoors), the value of the measured gas concentration can suddenly change.
Please use the Clip SGD after the gas concentration value has stabilized.
• The device is intended for use in normal atmospheric conditions, pressure 80 kPa (0.8
bar) to 110 kPa (1.1 bar); and air with normal oxygen content, typically 21 % v/v (volume/
volume).
