Calibrating the Device
Calibration ensures the device 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 must be done periodically throughout a sensor’s operating life. The data collected from each procedure is automatically sent to Blackline Live.
Configure the calibration schedule to match your company’s safety policy. Blackline recommends not exceeding 180 days without a calibration. These changes are made in the configuration profile on Blackline Live.
Sensors on a cartridge share 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. Sensors manually calibrated at the same time use a mixed-gas cylinder. Sensors individually calibrated use multiple single gas cylinders. If using multiple cylinders, you must repeat the calibration process for each cylinder. The gas concentration of the connected gas cylinder should match the gas concentration listed in the device’s calibration gas configuration in Blackline Live.
G7, G8, and EXO automatically communicate calibration data to Blackline Live at the device’s next scheduled synchronization.
Some cartridges require you to calibrate sensors in a specific order due to gas sensor cross sensitivity. For more details, see the following:
