Once 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
