You may adjust the flow upwards by pressing the POWER switch (arrow
up) or downwards by pressing the SELECT switch (arrow down). If you
set the flow to 0.0 LPM, the instrument will disable the pump and enter the
flow draw mode.
Please refer to section III. Normal Operation: Sample
Draw Mode for more information.
If you set the flow between 0.2 and
1.0 LPM, the instrument will automatically adjust the pump to the requested
flow rate using feedback from the built-in mass flow sensor.
Immediately after the flow rate screen appears, the ppm screen appears.
You may change the ppm by pressing the SELECT switch.
You may adjust the ppm upwards by pressing the POWER switch (arrow
up) or downwards by pressing the SELECT switch (arrow down). If you set
the ppm to 000 ppm, the instrument will not generate any gas, although it
will continue to pump.
The minimum and maximum ppm settings are dependent upon the flow rate
and the type of generating cell installed in the instrument. The Cal 2000 will
read the memory chip inside the generating cell and automatically display the
minimum and maximum ppm available for the flow rate that the instrument
is set to. The total range of the cell is divided into three sub ranges to allow
for appropriate resolution in each sub range. For all cells (excepting CLO
2
and the Micro-cells) the sub ranges at .5 LPM are .5 to 1 PPM,
