Imprimer la pageOnce the instrument has achieved a stable flow rate, it will
alternate between the ppm, air flow rate and stabilization
screen as described previously. At this point, you may press
SELECT to go to the status screens and adjust the ppm as
described earlier. If the flow rate changes significantly
during this period, the instrument will attempt to re-stabilize
at the new flow rate. The instrument operates identically to
the diffusion mode at this point.
WARNING: Do not adjust the flow rate to more than 0.0
LPM while the Cal 2000 is attached to a sample draw
unit or damage may occur to the instrument. Also, do
not attach the Cal 2000 to pumps drawing more than 5
LPM.

1.0 to 10.0 PPM and 10 to 50 PPM. When the end of a given
range is reached, pressing the appropriate up or down
arrow will automatically toggle the display to the next
appropriate range. Note that to obtain higher concentra-
tions of gas simply reduce the flow rate of the instrument.
Once the flow and concentration have been set, the
instrument will enter the stabilization period and the display
will alternate between the following three screens:
Stabilizing ...
Standby: 146 sec
1.00 ppm CL2
Standby: 145 sec
Flow: 0.5 lpm
Standby: 144 sec
When the instrument has finished counting down to zero
(0) seconds, it has reached 90% of its final output and will
enter the gas generating mode. In this mode, the instru-
ment will display the gas being generated, the flow rate, the
ppm setting and the time while running at these settings as
follows:
CL2 @ 0.5 lpm
1.0 ppm 00:00:00
