Wait until STABIL

falls below1.0 ppm.

This may take several

minutes.

The SPAN button now

appears during the

transition from zero to

span.

If either the ZERO or

SPAN

buttons fail to

appear see Section 11

for troubleshooting tips.

measurement

Press ENTR to changes the

measurements.

Press EXIT to leave the calibration

unchanged and return to the

previous menu.

ACTION:

Allow span gas to enter the sample port at the

rear of the instrument.

The value of

STABIL

may jump

significantly.

Wait until it falls back

below 1.0 ppm.

This may take several
