Calibrating G7
Calibration ensures G7 can accurately detect gas. This procedure adjusts sensor parameters while the sensors are exposed to a known concentration of gas for a set amount of time. Calibrations will need to be done periodically throughout a sensor’s operating life and the data collected from each procedure is sent to Blackline Live automatically.
The calibration schedule can be configured to match your company’s safety policy. These changes are made in the configuration profile on Blackline Live. All the sensors on a cartridge have the same calibration schedule, but if you choose to calibrate sensors individually, they can become due independent of the other sensors. Blackline recommends calibrating all the sensors on a cartridge in a single calibration process.
Blackline recommends not exceeding 180 days without a calibration.
G7 automatically communicates calibration data to Blackline Live at the device’s next scheduled synchronization and will remind you when a calibration is overdue. For more information on G7 calibration notifications, see Operational Notifications.
You can manually calibrate your G7 by applying the target gas to your gas sensors. To manually calibrate G7, you will need a calibration cap (ACC-S-CAL, ACC-Q-CAL) and tube (ACC-T2).
Alternatively, you can calibrate using G7 Dock (DOCK-P-NA/DOCK-P-EU). For more information on calibrating your device with G7 Dock, see the G7 Dock Technical User Manual on the Blackline Support site.
Gas cylinders
Sensors can be manually calibrated at the same time using one gas cylinder or individually using multiple gas cylinders. If using multiple cylinders, the manual calibration process must be repeated for each cylinder.
Some cartridges require you to calibrate sensors in a specific order due to gas sensor cross sensitivity. For details, see the following support articles on the Blackline Support site:
The gas concentration of the connected gas cylinder should match the gas concentration listed in your device’s calibration gas configuration in Blackline Live.
