port or from the internal zero source when zero gas is requested.
Cycle Time
The duration of each
Cal. Mode
(span and zero) when performing
Cycle
Mode
(refer to Section 3.4.10.1) or
Cal. Type
is set to
Timed
(refer to
Section 3.4.10.2).
Span Calibrate NOx
This field is used to perform a span calibration and should be only used
when a known concentration of span gas is running through the
reaction cell and the reading is stable.
Activating the span calibrate field for a named gas will open a dialog
box. Enter the concentration of the span gas that the instrument is
sampling and press
Accept
.
Zero Calibrate NO
This command is used to correct the zero calibration setting. This option
should be used only when zero gas is running through the reaction cell
(refer to Section 5.3 before using this command).
Zero Calibrate NO2
This command is used to correct the zero calibration setting. This option
should be used only when zero gas is running through the reaction cell
(refer to Section 5.3 before using this command).
Zero Calibrate NH3
This command is used to correct the zero calibration setting. This option
should be used only when zero gas is running through the reaction cell
(refer to Section 5.3 before using this command).
Pressure Calibration Menu
This menu allows the user to calibrate the pressure sensors (refer to
Section 3.4.11).
Pressure NO
This field displays the auxiliary valve manifold pressure measured
during the last calibration for the NO path.
Pressure NOx
This field displays the auxiliary valve manifold pressure measured
during the last calibration for the NO
X
path.
Pressure Nx
This field displays the auxiliary valve manifold pressure measured
during the last calibration for the N
X
path.
Temperature
Cell temperature when the last span calibration was performed.
Conv. Efficiency NO2
The overall efficiency of the conversion of NO
2
to NO, in the first
internal NO
2
to NO converter.
Conv. Efficiency NH3
The overall efficiency of the conversion of NH
3
to NO. Taking into
account the combined efficiency of both the External NH
3
converter and
the second internal NO
2
to NO converter.
3.4.10.1
Manual Mode
These items appear in the
Calibration Menu
when
Calibration Type
is set to
Manual.
Cal. Mode
When calibration type is set to
Manual
the instruments operational
mode can be chosen from the following:
Measure
: Is the normal measurement through the sample port.
Zero
: This mode will take air through the calibration port so that a
zero calibration can be performed. Data is flagged as zero data.
Span
: This mode will take air through the calibration port so that a
span calibration can be performed. Data is flagged as span data.
Cycle
: Performs a zero and a span
Cal. Mode
and then returns to
measure mode. The length of time spent measuring each calibration
