PROGRAMMING OF MULTIRAE
4 - 39
The MultiRAE PLUS monitor store three sets of correction
factors: one for the LEL sensor, one for the 10.6 eV PID
sensor and the other for the 11.7 eV PID sensor. Each set
consists of 20 to 40 different gases. The user can choose
one gas from the list to be the calibration gas and another
gas to be the measurement gas.
For example, the user can choose methane as the calibration
gas for the LEL sensor and select pentane as the
measurement gas. The MultiRAE PLUS monitor will
calculate the correction factor between these two gases and
convert the measured value of the LEL sensor into
equivalent concentration of the pentane gas.
Similarly, the user can choose one VOC gas for calibration
and choose another VOC gas for measurement. In addition,
the correction factor is different for the PID sensor due to
different energy of the UV lamp used in the PID sensor. The
user needs to choose the correct type of UV lamp (10.6 eV
or 11.7 eV) for the PID sensor in Section 4.8.4.
