Model 2010D Calibration Setup Page 6-
[17] For Dilution and GPT sequence types, you will be moved to a
field that allows you to select a source mass flow
controller that best suits the gas you are diluting. Enter
"1" or "2" here to select the desired MFC and press Enter
to proceed. The standard 2010D has only one source MFC,
making "1" the only choice.
[18] Unlike single-gas sequences, where the sequence type is
specified on page 1, Multi-gas sequences determine the type
of each point by what information is entered. If a special
symbol is selected for the Gas Source, the type for that
point is determined by the symbol. If a Gas Standard is
selected for the Gas Source, the following rules apply:
If the ozone is set to zero or left blank, the point is
considered a Dilution type.
If the primary gas concentration is zero or left blank
and there is an ozone concentration, the point is
considered an Ozone type.
If a concentration is entered for both the primary gas
and ozone, the point is assumed to be a GPT type.
Keeping these rules in mind, enter the primary gas and
ozone concentrations for this point (leaving a field blank
is equivalent to entering zero). Remember which units you
selected for concentration so that your input is correct.
If the number is not in the proper units, you will probably
be prompted with a pop-up box showing what the range of
concentrations must be for your entry. After entering each
number, press the Enter button. After entering both
concentrations, you will now be moved to the Duration
column.
Note that, regardless of the allowable range for primary
gas and ozone concentrations, zero (0) may be entered. If
zero is entered for the primary gas concentration (or if
"<Zero>" is selected as the Gas Source), the 2010D will
automatically turn off all source inlet valves to assure
that this is truly a "Zero" point. Likewise, if the ozone
concentration is set to zero, the ozone generator will be
turned off.
[19] Enter the number of minutes that you wish this calibration
point to remain active when the sequence is timer stepped.
Press the Enter button and you will be moved to the Gas
Source field of the next point.
