A multiplication factor used to adjust the concentration
measurement to the appropriate level (set at calibration).
This field displays the offset created from a zero calibration. This is
the concentration measured from zero air and is subtracted from
all readings.
The correction factor calculated from the background cycle (used
to eliminate background interferences).
Displays the correction factor applied to the concentration
measurement. This correction is for changes in pressure,
temperature and flows since the last calibration.
The standard deviation of the concentration. The calculation is as
follows:
Take a concentration value once every 2 minutes.
Store 25 of these samples in a first in, last out buffer.
Every 2 minutes, calculate the standard deviation of the current 25
samples. This is a microprocessor-generated field and cannot be
set by the user.
This reading is only valid if zero air or a steady concentration of
span gas has been supplied to the instrument for at least one hour.
Displays the actual reading on the analyser before the dilution
ratio is applied. If the Dilution ratio is 1 both undiluted CO and
diluted CO field will be the same value.
Undiluted CO2
[Input 1 is CO2 Option]
Displays the actual reading on the analyser before the dilution
ratio is applied. If the Dilution ratio is 1 both undiluted CO
2
and
diluted CO
2
field will be the same value.
Entering a value here will multiply the displayed and recorded
measurements by the dilution amount. For example, if the
instrument is measuring a source where the average concentration
is above the upper limit of the measurement range, a dilution
probe with a fixed ratio dilution ratio can be used to reduce the
level measured by the instrument, so for a 4:1 dilution ratio, enter
a value of 4.
Enter the ratio here so the instrument can display the correct
value on the instrument.
The default value is 1.00 (this indicates no dilution is applied).
Displays the current reading on the analyser after the dilution ratio
is applied. If the Dilution ratio is 1 both undiluted CO and diluted
CO field will be the same value.
Diluted CO2
[Input 1 is CO2 Option]
Displays the current reading on the analyser after the dilution ratio
is applied. If the Dilution ratio is 1 both undiluted CO
2
and diluted
CO
2
field will be the same value.
