Adjusting the sensor controls

CAUTION:Only perform the following steps if you are unable to set the correct calibration reading with the AIR/▲ and SHIFT/▼ buttons.

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 1.0 ppm to a maximum of 3.0 ppm, set the display to 2.0 ppm.

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 sensor in the front half of the bottom case. The sensor with wires connected to EC3 on the analog PCB displays its reading on the third line of the screen. The sensor connected to EC4 on the analog PCB displays its reading on the fourth line of the screen.

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 located next to the sensor on the side closest to the front of the instrument.

5.Press the POWER/ENTER button to set the span value. SINGLE CALIBRATION END displays, then the Single Calibration menu displays.

6.Place the top of the case in its original position, then secure it with the large screws you loosened in step 2.

7.Disconnect the tubing from the probe, then unscrew the regulator from the calibration cylinder.

8.With the Single Calibration menu displayed, press the SHIFT/▼ button until the prompt is next to the last channel, then press the SHIFT/▼ button again. The ESCAPE message displays.

9.Press the POWER/ENTER button to return to the Calibration menu.

10.Press the SHIFT/▼ button to place the prompt next to the NORMAL OPERATION menu option, then press the POWER/ ENTER button to return to the normal screen.
