Presets and Response Factors
Presets simplify Memory Slot programming, and provide standard
response factors and alarm levels for approximately 100 compounds.
The name, response factor and three alarm levels are all set from the
preset.
You can change any of the values entered in the Memory Slots. Chan-
ges made to the library information that has been loaded into a Preset
will have no effect on the original library entry.
The response factors were determined over the range 5 - 500 ppm,
based on a 100-ppm isobutylene calibration. Isobutylene RF = 1.0.
The following formula is used for calculation of response factors:
A response factor less than 1.0 indicates a compound response bet-
ter than that of isobutylene. A response factor greater than 1.0 indica-
tes a lower response than that of isobutylene.

NOTE:
It does not matter which response factor is entered. The Multi-
PID 2’s response is not specific to any one compound. The dis-
played reading represents the total concentration of all ioniz-
able compounds in the sample.
