Thresholds

The Thresholds section of the dialog box displays upper and lower thresholds for the ambient temperature and relative humidity values. The Measure-UPS device uses these thresholds to determine whether the current temperature and humidity are within acceptable limits.

Note:
See
Monitoring Preferences... for information about how to choose Celsius (the default) or Fahrenheit to display the Measure-UPS temperature values on the main screen. The "Measure-UPS Parameters" dialog box always displays the temperature values in Celsius. To convert a Celsius temperature to a Fahrenheit value to use for a temperature threshold, use the following formula:

The following table identifies the default threshold values:

Low Temperature 20 degrees Celsius (68.00 degrees Fahrenheit)
High Temperature 65 degrees Celsius (149.00 degrees Fahrenheit)
Low Humidity 20.00% relative humidity
High Humidity 80.00% relative humidity

To change an enabled threshold value, type the new value into the data field for the threshold. See the user's manual for your Measure-UPS or SmartSlot Measure-UPS II for the temperature and humidity ranges that your Measure-UPS device can measure.

If the environmental temperature or humidity goes out-of-range, PowerChute plus generates an out-of-range FlexEvent: Ambient Temp Out Of Rangeor Humidity Out Of Range.

When the environmental temperature or humidity returns to an acceptable range, PowerChute plus generates an in-range FlexEvent: Ambient Temp in Rangeor Humidity In Range.

PowerChute plus also displays ambient temperature and humidity in the Data Fields window of the main screen. If ambient temperature or humidity is outside the range of the low and high thresholds, the data for the corresponding field on the main screen is displayed in red.
