The Multi-PID 2’s 15 memory slots can be used to store calibration
information for 15 different span gases.
The Multi-PID 2 will always detect all ionizable compounds present in
a sample regardless of the response factor (RF) selected.
It is often impractical to carry a range of different standards into the
field. Approximate results can be obtained by calibrating the Multi-
PID 2 with the recommended span gas and entering the appropriate
response factor.
The response factor is based on the ratio of the response of the spe-
cific compound to the response of the span gas. The response factor
multiplies the Multi-PID 2’s reading, then displays and records it. See
table 5 on page 97 for response factors. This list should be used only
for concentrations up to 500 ppm of the specific compound, as
response factors change with concentration.
NOTE:
In the case of calibration or when changing the configuration,
the data logger has to be deleted manually to ensure consistant
data.
NOTE:
Even if the Multi-PID 2 has been calibrated with a specific com-
pound, its response is not specific and the presence of another
ionizable impurity may render the numerical result invalid.
WARNING:
The Multi-PID 2 is a total VOC instrument and will
ALWAYS respond to all ionizable compounds pre-
sent in a sample. The Multi-PID 2 will NEVER
respond only to a specific compound if an RF is pro-
grammed. It is the responsibility of the user to be
aware of the limitations of PID instruments
