K-factor
K-factor is a feature that allows gases’ cross-sensitivity to be employed to measure a different
gas using gas calibrations of a selected gas. The detector’s readings are modified by the known
relationship between the two gases. For example, a 5ppm concentration of Gas A is seen by the
detector as the same as a 5.8 ppm concentration of Gas B. The K-factor is 1.2 (5.8 ÷ 5 = 1.16 = 1.2
when rounded to one decimal place).
When k-factor is enabled, gas levels will be multiplied by k-factor automatically. Alarm levels
should be checked again after enabling the k-factor.
NOTE
When mg/m3 is selected as a measurement unit, k-factor is not allowed to be ON.
Non-Zero Warning
When this option is ON and non-zero gas concentration is detected, an informative event will be
recorded and non-zero warning status will be reported to DAq. The point with non-zero warning
will blink in green.
