1.Use the AIR/▲ and SHIFT/▼ buttons to set the reading to the middle of the range in which you can currently adjust the reading. For example, if you can set the reading from a minimum of 10% LEL to a maximum of 40% LEL, set the display to 25% LEL.

2.Unscrew the two large screws on the top of the case, then carefully lift the top of the case and lay it aside.

3.Locate the infrared methane sensor in the front half of the bottom case. It is connected to the EC4 socket on the analog PCB.

4.Adjust the sensor’s SPAN control one turn and observe the display reading. Continue to adjust the SPAN control until the display reading matches the concentration of the calibration cylinder.

The SPAN control is on the top edge of the ampliﬁer and is the control closest to the front of the instrument.

5.Place the top of the case in its original position, then secure it with the large screws you loosened in step 5.

6.Continue with the normal calibration procedure.

Replacing Infrared Methane Sensors

Return the Eagle to RKI Instruments, Inc., for replacement of the infrared methane sensor when:

•The infrared methane channel cannot be calibrated correctly.

•The infrared methane reading cannot be set to zero by the Demand Zero command.
