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.
Alarm
Alarm levels can be selected from the preset or entered. When custom is selected, alarm levels
are edited manually.
Copy Point Configurations
When multiple points are configured in same way, an operator can configure one point and
copy it to other points to save time. Tap on the APPLY TO OTHERS button.
