of the full scale value of the target gas. For example, if you are calibrating the

combustible gas channel, your calibration cylinder should have a

combustible gas concentration between 10% LEL and 50% LEL. For the

oxygen channel, RKI Instruments, Inc. recommends using 100% nitrogen to

perform the adjustment but any concentration between 0% oxygen (100%

nitrogen) and 17% oxygen can be used to make the adjustment.

NOTE: If your combustible gas channel is calibrated to a gas other than

methane, use an appropriate gas cylinder to perform the calibration.

CAUTION: The single calibration method does not have a “FAIL”

notification. If a sensor cannot be set to agree with the

calibration source, see “Troubleshooting” on page 143.
