Mounting a new NO-Sensor
!
For initial calibration, it is imperative that the hoses (1) are of the same length and are
connected to the gas outlets of the exhaust-gas analyzer in the same manner as will
actually be the case during subsequent operation by the user.
i
If the outlet hoses are shortened or lengthened, calibration must be performed again.
The signal from the NO measuring sensor is very sensitive to vibrations from the
pump. The strength of these vibrations depends upon the length of the outlet hoses.
Following successful calibration, the timer for monitoring the set recalibration interval
is started.
- Start evaluation by clicking on
Yes
or
selecting this button with the
z
key and
confirming with
E
.
Using the keyboard, enter the calibrating-
gas value in
ppm NO.
i
If the calibrating-gas value is stated
on the certificate in
mg/m
3
you must
convert this value to
ppm
.
The formula required for conversion
is:
Test gas value x 0.737.
Example:
2179 mg/m
3
=
1606 ppm NO
