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 PX3 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 PX3
does NOT perform the "deassertion" action.

If the temperature drops to 17 degrees Celsius or lower, the PX3
performs the "deassertion" action to announce the end of the "above
upper warning" state.
Default Voltage and Current Thresholds
The following are factory-default voltage and current thresholds applied
to a Raritan power product. There are no default values set for
lower
current thresholds because lower thresholds are not useful.
Availability of diverse thresholds depends on the capability of the model
you purchased.
Single-phase inlets or outlets:

RMS voltage:
Threshold Default value
Lower critical -6% of minimum rating
Lower warning -3% of minimum rating
Upper warning +3% of maximum rating
Upper critical +6% of maximum rating
Hysteresis 2V

RMS current:
Threshold Default value
Upper warning 65% of rating
Upper critical 80% of rating
