To Begin

Press

Enter

to begin the zero calibration. After a few seconds the first

of five zeroing screens appears. The number in the upper left hand corner is
the first-stage zero offset. The microprocessor samples the output at a prede-
termined rate. It calculates the differences between successive samplings and
displays the rate of change as Slope= a value in parts per million per second
(ppm/s).

#### % Zero
Slope=#### ppm/s

NOTE: It takes several seconds for the true

Slope

value to display. Wait about

10 seconds. Then, wait until

Slope

is sufficiently close to zero before

pressing Enter to finish zeroing.

Slope

is given in ppm/s.

Generally, you have a good zero when Slope is less than 0.05 ppm/s

for about 30 seconds. When Slope is close enough to zero, press

Enter

. In a

few seconds, the screen will update.

Once span settling completes, the information is stored in the micropro-

cessor, and the instrument automatically returns to

Analyze

mode.
