Appendix E: Additional BCM2 Information
Assumption:
Upper Warning threshold is enabled.
Upper Warning = 20 (degrees Celsius)
Deassertion Hysteresis = 3 (degrees Celsius)
"Deassertion" level = 20-3 = 17 (degrees Celsius)
When the BCM2 detects that a temperature sensor's reading drops
below 20 degrees Celsius, moving from the "above upper warning" range
to the "normal" range, either of the following may occur:
• If the temperature falls between 20 and 17 degrees Celsius, the
BCM2 does NOT perform the "deassertion" action.
• If the temperature drops to 17 degrees Celsius or lower, the BCM2
performs the "deassertion" action to announce the end of the "above
upper warning" state.
Altitude Correction Factors
If a Raritan differential air pressure sensor is attached to your device,
the altitude you enter for the device can serve as an altitude correction
factor. That is, the reading of the differential air pressure sensor will be
multiplied by the correction factor to get a correct reading.
This table shows the relationship between different altitudes and
correction factors.
