might see up to 75% H

, the span gas should contain at least 75% H
2
in its chemistry. The gases
should be “Certified Primary Standards” or equivalent accuracy. Then, follow these steps:
1.
Note the percentages of the sensor gas in each gas source (zero and span).
2.
Ensure that the system is purged of any latent gas.
3.
Flow the zero gas until the gas reading on the web page stabilizes. For the zero
calibration, the zero gas can flow directly through the sensor as shown in the illustration
below. Flow should be 1 to 2 cfh.

4.
Enter the target gas concentration in the “Enter gas concentration (%)” field.
5.
Press the “Calibrate” button. A Calibration Timer will count down.
6.
Once the Calibration Timer has counted down, the zero value will be calibrated.
NOTE:The remaining steps for the span gas require a different flow setup so please read the
instructions carefully.
7.
Ensure that the system is purged of any latent gas.
8.
Start by flowing the span gas through the sensor similar to the zero gas calibration (see
illustration below). Wait until the gas reading on the web page stabilizes.
