CALIBRATION PROCEDURE FOR Models 2000 & 2010 ANALYZER
For TURBINE GENERATOR APPLICATION
The ranges for this analyzer are:
Range 1: 0-100% Air in CO2
Range 2: 0-100% H2 in CO2
Range 3: 80-100% H2 in Air
Cal Range: 0-20% N2-H2
The following instructions show how to calibrate each range in the analyzer
independently. If all ranges must be calibrated using the Cal range, go to the cal
range calibration section and following the instructions.
CALIBRATE RANGE 1
1 Select the RANGE function on the main menu and place the analyzer in Range
1. DO THIS, EVEN IF ANALYZER IS IN RANGE 1.
2 Feed zero gas to analyzer and purge for the time needed to get readings that are
leveled. Feed CO2 to the analyzer
3 Press ZERO. You have the option to select AUTO or MANual. AUTO lets the
analyzer adjust itself and may take longer while in MANual mode the operator
has to adjust the zero reading on the display manually using the Up and Down
arrows.
4 Press ZERO select manual press the arrow > hold until OK is displayed in the
upper right corner of the VFD display.
5 If you choose manual, you first will do the Coarse zero adjustment using the Up
and Down arrows. Adjust until display reads as close to zero as you can then
press Enter. Now do the Fine zero adjustment using the Up and Down arrows
until the display reads as close to zero as possible then press Enter. Now the
analyzer will do the final step which is the Software zero adjustment. No input
is required and the analyzer will return automatically to the Analyze mode when
done.
6 When the analyzer finishes the zero, feed the span gas and purge for the time
needed to get readings that are leveled. Feed Air to the analyzer
