Calibration Procedures

Model GFC7000TA Carbon Dioxide Analyzer

STEP THREE: Perform the Zero/Span Calibration Procedure:

SAMPLE*	RANGE = 500.000 PPM	CO2 =XXX.X
< TST TST > CAL		SETUP


SAMPLE	STABIL=XXX.X PPM	CO2 =XXX.X
< TST TST > CAL		SETUP

Set the Display to show the STABIL test function.

This function calculates the

stability of the CO2 measurement

ACTION:

Allow zero gas to enter the sample port at the

rear of the instrument.

M-P CAL	STABIL=XXX.X PPM	CO2 =XXX.X
< TST TST > CAL		SETUP


M-P CAL	STABIL=XXX.X PPM	CO2 =XXX.X
< TST TST > ZERO CONC		EXIT

Wait until STABIL falls below 1.0 ppm.

This may take several

minutes.

The SPAN button

appears.

If either the ZERO or SPAN buttons fail to appear see Section 11 for troubleshooting tips.

		ACTION:
Allow span gas to enter the sample port at the
	rear of the instrument.

< TST TST >	SPAN		CONC	EXIT
					Press ENTR to change the
					Press ENTR to change the
M-P CAL		= 500.000 PPM		CO2 =XXX.X	OFFSET & SLOPE values for the

< TST TST > ENTR		SPAN	CONC	EXIT	Press EXIT to leave the calibration
< TST TST > ENTR		SPAN	CONC	EXIT	unchanged and return to the
					unchanged and return to the
					previous menu.

M-P CAL	RANGE = 500.000 PPM			CO2 =XXX.X
					EXIT returns to the main
< TST TST > ENTR		CONC		EXIT	SAMPLE display

If the ZERO or SPAN buttons are not displayed, this means that the measurement made during that part of the procedure is too far out of the allowable range to do allow a reliable calibration. The reason for this must be determined before the analyzer can be calibrated. See Section 11 for troubleshooting tips.
