Serinus 40 User Manual 2.2
This field is used to correct the zero calibration setting on the NO
2
.
This option should be used only when zero gas is running through
the measurement cell. When this is stable activate the Zero
Calibrate (NO
2
) field, a window will open with editable numbers.
Leave the numbers at 0000.000 and select Accept.
This menu allows the user to calibrate the pressure sensors (refer
to Section 5.6).
This field displays the measured manifold pressure during the last
calibration (for NO reference).
This field displays the measured manifold pressure during the last
calibration (for NO
X
reference).
Cell temperature when the last span calibration was performed.
The efficiency of the conversion of NO
2
to NO, in the NO
2
to NO
converter.
3.5.12 Manual Mode
These items appear in the calibration menu when Calibration Type is set to Manual.
Calibration Mode
(Only accessible once
instrument has completed
warm-up)
When calibration type is set to Manual the instrument’s
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, then a span then returns to measure
mode. The length of time spent measuring calibration gases is set
in cycle time (below).
The time period that the zero and then span ports will be selected
when Calibration Mode is set to Cycle. Users can set the time
from (5 to 59 minutes).
