Laser One
The document begins with a declaration that the equipment complies with EU safety and performance standards.
This section stresses the importance of understanding the manual before use, especially in hazardous environments. It specifies that the battery must be replaced and charged only in non-hazardous areas using specific QED components. Unauthorized opening of the device voids its certification and warranty.
The LASER ONE is a digital gas detection instrument designed for measuring low concentrations of Methane. It is suitable for natural gas network surveys and laboratory gas analysis, using laser technology for selective Methane measurement, providing reliable results even in the presence of other gases.
An overview of the instrument's interface, including connections, display, and navigation system, is provided.
Details on switching the instrument on and off, starting a survey, and using optional GPS features are included.
Users can adjust the measurement range, set alarm thresholds, and configure acoustic and visual alarms. The device supports Bluetooth connectivity and provides battery recharging instructions.
Guidelines for replacing the battery pack and hydrophobic filter are included, along with information on service and calibration.
This section covers service and calibration procedures, as well as alarms and error information.
Information on the warranty and available accessories for the LASER ONE is provided.
Several appendices cover safe use, technical specifications, disposal information, and Bluetooth module compliance across different regions.
The instrument features an ON/OFF button with backlight, a function button, a buzzer, a jogdial, LED alarm lights, and impact bumpers. It includes connectors for a gas sample inlet and battery charger/data download.
The display shows pump, buzzer, and battery status, methane measurement, and unit of measurement. GPS and Bluetooth statuses are optional. The jogdial allows menu navigation, with gas values displayed during menu activity.
Switching On/Off: Press the ON/OFF button to activate the display and initiate a start sequence. The instrument warms up and self-calibrates in about 20 seconds. To switch off, hold the ON/OFF button until a shut-off message appears.
The GPS, when activated, logs gas levels with coordinates, storing data for up to 8 hours. GPS activation is done via the jogdial menu. Signal strength affects GPS performance, with open areas providing quicker fixes.
Leaks can be saved when GPS is active. Data deletion is irreversible and done through the jogdial menu.
The LASER ONE uses a membrane pump with a typical flow of 0.8 l/m. It includes internal and external hydrophobic filters to protect against dust and water ingress. Malfunctions are indicated by a "PUMP ERROR" message.
Measurement Range: Methane is measured selectively, with dual range display switching from ppmVol to %Vol.
Alarm Threshold: Adjustable via the jogdial, with a minimum threshold of 1 ppm.
Alarms: Acoustic and visual alarms activate when thresholds are exceeded.
Backlight: Adjustable illumination levels.
Bluetooth: Optional feature, always active if installed.
The rechargeable battery pack requires specific charging conditions and has a typical operational time of 10 hours. Charging should occur in non-hazardous areas.
Battery and filter replacements should be conducted in safe areas. Regular servicing and annual calibration are recommended.
Testing involves a 10ppm cylinder and a flow regulator. Calibration dates are displayed during warm-up and on the instrument label.
The document outlines maintenance procedures, including periodic checks of the hydrophobic internal filter, and details various alarm conditions and error messages, such as GAS alarms, pump errors, and battery warnings.
QED offers a 12-month warranty for the LASER ONE gas analyser, covering defects due to faulty parts or workmanship. The warranty requires proof of purchase and adherence to recommended service and calibration schedules.
The document lists various accessories available for the LASER ONE, including carrying cases, straps, probes, filters, and power supplies.
Safety instructions emphasize the importance of using the LASER ONE in appropriate environments and following the user manual. Technical specifications include measurement ranges, sensitivity, accuracy, response time, and environmental conditions for operation and storage.
The document highlights the importance of disposing of the LASER ONE through registered recycling schemes in compliance with the Waste Electrical and Electronic Equipment directive (WEEE).
To reduce interference, consider reorienting or relocating the receiving antenna, increasing the distance between the equipment and receiver, connecting the equipment to a different circuit, or consulting a radio/TV technician.
The device includes transmitter module IC: 6514A-RN42 and complies with Industry Canada RSS standards.
Under Industry Canada regulations, the radio transmitter must use an approved antenna type and gain to minimize interference.
The Bluetooth module complies with the R&TTE Directive 1999/5/EC.
