3.1.3 Dual Range Calibration

If the analyzer is being operated in Dual Range mode or Auto-Ranging mode, then the High and Low ranges must be independently calibrated. When the analyzer is in Dual or Auto Range mode you will be prompted to enter the range to calibrate whenever you enter a calibration command from the front panel. Press HIGH or LOW followed by ENTR button to proceed with the calibration. To calibrate the other range you must exit to the sample menu and restart the calibration. See Section 4.6 for more information on the Range Modes. The following procedure shows an example of how to calibrate the two ranges with calibration gas coming in through the sample port:

Step	Action	Comment

1.	Press CAL	Analyzer enters M-P calibration mode. Calibration gas
		source should be set to deliver zero gas to the sample
		port.

2.	Press LOW-ENTR	Select range to calibrate.

3.	Wait 15 min.	Wait for CO reading to stabilize at zero value.

4.	Press ZERO-ENTR	Changes calibration equations for Low range so
		analyzer will read zero.

5.	Press CONC	Enter span gas concentration for Low range.

6.	Key in span concentration	Enter span gas concentration for Low Range. Set
		calibration gas source to deliver span concentration.
7.	Press ENTR

8.	Wait 15 min.	Wait for CO reading to stabilize at span value.

9.	Press SPAN-ENTR	Changes calibration equations for Low range so
		analyzer will read span value.

10.	Press EXIT	Exits back to sample menu.

Repeat steps 1-10 for High range.
