Manually Calibrating with Multiple Gas Cylinders
If you do not have a single gas cylinder containing all the required gases to calibrate your Blackline Safety device, you will need multiple gas cylinders to complete these tests on the different sensors. This article describes how to manually calibrate using multiple gas cylinders.
Attach fixed flow regulators to your gas cylinders and connect each regulator to a calibration cap using sample tubing.
- Navigate to Gas options using the up and down arrows, then press OK.
- Navigate to Calibration using the up and down arrows and press OK.
- When prompted, select Yes to start the calibration.
G7 will do a self test of its lights, sounds, and vibration.
- G7 zeros all the sensors before calibration starts. Press OK.
- Select Start span and press OK to start the calibration.
G7 will begin to count down from 60. - Start the gas flow to apply gas to your selected sensor(s).
- When your G7 prompts you, turn your gas off, press OK.
Any sensors you previously cleared will appear on the Select gas mix screen.
