6. Install the regulator on the span calibra-
tion cylinder and connect tubing from 
the regulator to the inlet fitting on the 
top of the Model IAQ10. 
7. Use 
5 and 6 to adjust the concentra-
tion displayed on the Model IAQ10 to 
match the concentration on the span gas 
cylinder. 
8. Press and release the READ key to take 
a span gas reading. The Model IAQ10 
starts a 60-second countdown. When the 
countdown reaches zero, the instrument 
returns to the normal measurement 
mode. 
9. With the gas still connected, observe the 
reading on the display. It should indi-
cate the span gas concentration. If not, 
repeat this procedure. 
10. If the displayed reading is accurate, 
remove the regulator and tubing. The 
calibration is now complete. 
11. Before taking measurements, turn the 
instrument off and move DIP switch #7 
back to OFF.
