3.6.2.4.Zero/Span Calibration

To perform the zero/span calibration procedure, press:

SAMPLE	RANGE=0.0 PPm	CO= XX.XX
< TST TST >	CAL	SETUP
	Toggle TST> button until ...
SAMPLE	STABIL= XXXX PPM	CO=XX.XX
< TST TST >	CAL	SETUP

Set the Display to show the STABIL test function. This function calculates the stability of the CO measurement.

Allow zero gas to enter the sample port

at the rear of the analyzer.

Wait until STABIL falls below 0.5 ppm.

This may take several

minutes.

SAMPLE	STABIL= XXXX PPM	CO=XX.XX

M-P CAL	STABIL= XXXX PPM		CO=XX.XX
<TST TST>	ZERO CONC		EXIT
M-P CAL	STABIL= XXXX PPM		CO=XX.XX
<TST TST> ENTR		CONC	EXIT

Press ENTR to changes the OFFSET & SLOPE values for the CO measurements.

Press EXIT to leave the calibration unchanged and

return to the previous

menu.
