b) Install a regulator on the clean air/known percent oxygen content gas
cylinder.
c) Attach a length of calibration tubing (PVC tubing, 3/16-in. OD, 5/16-in. OD)
from the regulator on the cylinder to the IP filter on the bottom of the sensor.
d) Release the clean air/known percent oxygen specified calibration gas to the
sensor.
Note
If you need a long length of calibration tubing to reach the device, make
allowances for a delay in response time from the sensor while the clean air
travels the length of the calibration tubing.
e) Perform Step 5 through Step 7.
f) Turn off the clean air/known percent oxygen specified calibration gas when
the sensor is correctly zeroed.
