GAS DETECTION Included with your G7 Single-gas or Multi-gas cartridge is a calibration cap and tubing for bump tests and calibrations. Alternatively, bump tests and calibrations can be completed using a G7 Dock. Only perform bump test and calibrations in a safe environment. For more information and instructions on bumping or calibrating with G7 Dock, refer to the G7 Dock technical user manual. BUMP TEST What is a bump test? It is safe practice to regularly test gas sensors by applying the target gas.
Tubing Single-gas calibration cap Tubing Multi-gas calibration cap 16 || G7 TECHNICAL USER MANUAL
CALIBRATION What is calibration? Gas sensors periodically need to be calibrated by applying a known concentration of gas for a set amount of time. This procedure ensures the gas sensor can accurately detect gas levels throughout its operating life. The calibration schedule depends on your company’s safety policy. Blackline recommends not exceeding 180 days without a calibration. How do I calibrate? 1. Attach tubing to the calibration cap 2.
BUMP TEST & CALIBRATION REMINDER WINDOW What is the bump test and calibration reminder window? A bump test and calibration reminder window can be customized from G7’s configuration profile in Blackline Live. This setting will prompt the device to show a bump test or calibration reminder alarm upon startup if one of these tests is due within the configured window of time.
ZERO SENSORS What is zeroing? If G7 is not reading zero and you know you are in an atmosphere with no gas, your gas sensor readings may have shifted. If this happens, it is best to calibrate your sensors. If you are unable to preform a calibration, you can zero your sensors to reset the baseline. G7 can be configured to automatically or manually zero on start-up when you turn on your device from the configuration profile in Blackline Live. NOTE: The baseline reading for oxygen is 20.9.
GAS DETECTION FEATURES Once you have completed a bump test and calibration, G7 is ready to monitor and notify you of gas exposure. Gas detection alarms will notify you with either a yellow warning alarm or a red alert depending on the gas level measured. All settings are customizable in Blackline Live. Speak to your safety supervisor to learn about how your gas features are configured.
UNDER LIMIT When does G7 trigger an under limit yellow warning alarm? If a gas sensor’s baseline shifts, it’s reading will shift accordingly and become unreliable. When this happens, the presence of gas can still be measured, but cannot be converted into an accurate reading. G7 will inform you of such an event with a yellow warning alarm. A calibration will be required to ensure the sensors are accurately detecting gas levels.
RED ALERT GAS FEATURES Rapid Blinking HIGH ALERT FOR GAS When does G7 trigger a high alert for gas? If a gas sensor detects gas levels above the high gas concentration threshold configured by your safety supervisor. NOTE: A G7 with O2 sensors will trigger red alerts in both oxygen-deficient and oxygenenriched situations. STEL (SHORT TERM EXPOSURE LIMIT) ALERT When does G7 trigger a STEL alert? If a gas sensor detects you have reached the short-term exposure limit configured by your safety supervisor.
TWA (TIME WEIGHTED AVERAGE) ALERT When does G7 trigger a TWA alert? If a toxic sensor detects you have exceeded the average allowable amount of gas during an eight-hour period. NOTE: The two TWA measuring methods available for use on your G7 are: OSHA (United States Department of Labor Occupational Safety and Health Administration) or ACGIH (American Conference of Governmental Industrial Hygienists). OSHA is defined as a rolling average of gas exposure accumulated over an eight-hour period of operation.
CONFIGURATION MODES Configuration modes are customized in the G7 configuration profile on Blackline Live. Each profile supports up to a total of five ‘modes’ . These modes allow G7 to temporarily change its behavior for different situations, and can be turned on and off through G7’s interface. AVAILABLE MODES Normal This mode is the configuration you determine for everyday operation. G7 will operate using this mode as a default.
To enter a mode from the modes menu: 1. Press OK to enter G7’s main menu 2. Use the up and down arrows to navigate to modes 3. Press OK to enter the modes menu 4. Select the mode you wish to enter 5.

CARTRIDGES GAS CARTRIDGE REPLACEMENT PROGRAM What do I do when I need a new gas cartridge? If you have an uninterrupted service plan for your G7 gas cartridge, Blackline will replace expired cartridges for you free of charge. To inquire about or request new cartridges, please contact our Customer Care team or your distributor. CHANGING CARTRIDGES How do I change my G7 cartridge? 1. Power off G7 2. Using a Phillips #1 screwdriver, remove the screws on each side of the device 3. Pull up on the cartridge 4.
CARTRIDGE CARE Sensor contaminants Gas sensors are susceptible to contamination by a variety of common chemicals, reducing or eliminating their sensitivity. Care should be taken when using silicones, cleaners, solvents and lubricants in close proximity to sensors as exposure may cause permanent damage to the sensor. If a device is exposed to a new chemical or compound, it is best practice to bump test and calibrate units to ensure proper sensor function is maintained.
MULTI-GAS PUMP CARTRIDGE USING PUMP How do I turn pump on? 1. Ensure G7 is equipped with a multi-pump cartridge and pumped modes, such as pre-entry, leak check or pump run 2. From G7’s main or secondary menu, select the pumped mode you wish to enter 3. Attach tubing, and perform a block test by following the instructions on G7’s screen 4. G7’s screen will invert, and the pump icon will show in the info bar to let you know pump is running 1:48 Pump on Hose L: 5m ~300 ml/min. Sample 75 sec.
What is flow rate? Flow rate is the speed at which air is passing over your device’s sensors. In order to provide accurate gas readings, flow rate needs to be above 150 ml/min. A flow rate less than 150 ml/min will result in a pump block yellow warning alarm. By default, Blackline’s pump aims to maintain a flow rate of 300ml/min and G7 will automatically adjust its pump speed to maintain this rate. PUMP OPTIONS Settings for pump can be found in G7’s main menu, under settings > pump options.
