Calibrating Overview

An overview of the calibration process for G8.

Calibration ensures G8 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 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 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.

Note: Blackline recommends not exceeding 180 days between calibrations.
G8 automatically communicates calibration data to Blackline Live at the device's next scheduled synchronization and reminds you when a calibration is overdue. For more information on G8 calibration notifications, see No Content found for /db/organizations/blacklinesafety/repositories/production/content/documents/G8/G8_notifications_operational_overview.dita.
You can manually calibrate your G8 by applying the target gas to your gas sensors. To manually calibrate G8, you need a calibration cap (ACC-Q-CAL or ACC-S-CAL), tube (ACC-T2), and a fixed-flow regulator specific to the gases being calibrated:
  • Most gases: ACC-REG +ACC-T2

  • Cl2 NH3 SO2 and HF: ACC-REG-1L and ACC-FEP-T2

Alternatively, you can calibrate using G7/G8 Dock (DOCK-P-NA/DOCK-P-EU). For more information on calibrating your device with G7/G8 Dock, see the G7/G8 Dock Technical User Manual.
