Press CO2: ENTR to
initiate zero point
calibration of the
O2 sensor.
Press CO2: ENTR to
initiate span point
calibration of the
O2 sensor.
The SPAN key now appears
during the transition from
zero to span.
You may see both keys.
If either the ZERO or SPAN

Set the Display to show
the CO2 STB test
function.
This function calculates
the stability of the CO
measurement.
Wait until CO2 STB
falls below 0.01%.
This may take several
minutes.
Press ENTR to changes
the OFFSET & SLOPE
values for the O

measurement.
Press EXIT to leave the
calibration unchanged and
return to the previous
menu.
