Enter the primary gas (or ozone) concentration for this point.
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.
Enter the number and press the Enter button. You will now be
moved either to the Duration column of this screen or to the
ozone column if this is a GPT sequence type.
If this is a GPT sequence, enter an ozone concentration. The
ozone concentration should be set to the amount of NO2 desired
in the output gas for this point and should be less than the
primary gas (NO) concentration. After entering the ozone,
press Enter to move to the Duration field.
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, the
2010D
will
automatically turn off all source inlet valves to assure that
this is truly a "Zero" point. Likewise, for Ozone and GPT
sequences, if the ozone concentration is set to zero, the
ozone generator will be turned off.
[16] 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 either be moved to the
next point or to the Point Status Outputs area of the screen
if you previously assigned the Point Status Outputs in the
Digital I/O Group Assignments screen (page 6-21).
[17] If you have previously assigned User Digital I/O Bits to Point
Status Outputs you will be prompted to select which status
outputs are associated with this particular calibration point.
Bit positions indicated by a 1 or a 0 have been reserved for
Point Status Outputs and are available to signal an external
device when this calibration point is active. Bit positions
indicated by a decimal point have been assigned to other
purposes and may not be changed here. If all the bits are
indicated by decimal points and this feature is needed, then
Sequence Status Output bits must be assigned in the Digital
I/O Group Assignments screen under the Remote Activation menu
(see Page 6-21).
A 1 or a 0 can be inserted in each bit location that is not
indicated by a decimal point. When this point is
subsequently activated, the pattern of 1's and 0's will be
presented on the User Digital I/O Bits as lows (0V) and
highs (5V), respectively. After you have inserted your bit
pattern, press the Enter button. You will be moved to
primary gas (or ozone) concentration field for the next
point.
