This value is the millivolt set point that will stop the COF/PF adjustment. This will prevent
adjustments from being made when the proper conditions are not met. The minimum millivolts set point
should be slightly higher than the minimum millivoltage that is expected. The value will range from 0 to
2000.
Min MV Stops pump
This value is a switch that will determine if the instrument will turn off the pump when the minimum
millivolts value is reached. This will occur
only if the pump is set to “Auto Sample” mode
. To change the
pump status, go to
Pump Control
(menu option 4). To use this feature, the instrument should be
communicating with an instrument that can provide real-time probe millivolt data. This is another feature
that is intended to prevent the analyzer from pulling a bad sample and potentially damaging the sensors.
The value will be either Yes (1) or No (0).
Maximum Adjustment
This is the largest increment of change that will be applied to automatic COF/PF adjustments. This
will dictate the size of the steps the instrument takes when it adjusts the COF or PF of the control
instrument. A higher value will result in more speed in achieving the desired set point, but a lower value will
result in a smoother approach. The Maximum Adjustment feature should be coordinated with the Update
Interval time to achieve the desired responsiveness. The value will range from 0 to 20.
Maximum COF/PF
This value establishes the upper allowable limit for the COF/PF. For example, if this is set to 300,
then the instrument will make changes to the COF/PF until it is at 300, but it will not go any higher. The
value will range from 0 to 999.
Minimum COF/PF
This value establishes the lower allowable limit for the COF/PF. For example, if this is set to 100,
then the instrument will make changes to the COF/PF until it is at 100, but it will not go any lower. The
value will range from 0 to 999.
IR Mode
This is a selection to determine if the instrument is running in Automatic or Manual mode. When in
Manual mode, no changes will be made to the COF/PF of the control instrument. There are two Automatic
modes to select from. COF/PF Adj. %C will make adjustments to the COF/PF in the atmosphere controller
based on the calculated percent carbon. This is the preferred method of adjustment. The other Automatic
mode, COF/PF adj. CO, will make adjustments based only on the measured level of CO and not on the
carbon calculation.
To cycle between each selection, press the circular arrow key to change the IR Mode.
On delay (in minutes)
This determines the amount of time it takes for the pump to turn on after both of the operating
parameters (temperature and millivolts) have been met. The value will range from 0 to 60 minutes,
adjustable in tenths of a minute.
Off delay (in minutes)
This determines the amount of time it takes for the pump to turn off after either of the operating
parameters (temperature and millivolts) fall outside of the pre-defined boundaries. The value will range
from 0 to 60 minutes, adjustable in tenths of a minute.
Update interval (in minutes)
This determines the amount of time between automatic updates of the COF/PF on the control
instrument. This is adjustable in one-minute increments. It is recommended that the Update Interval be set
to one (1) minute, and the Maximum Adjustment set to one (1) point. This will allow the COF/PF to be
adjusted frequently, but only a small amount at a time, which will result in smooth operation. The value will
range from 0 to 20.
Sample delay (in minutes)
The value will range from 0 to 300 tenths of a minute.
