Measurement Status
The Measurement Status page provides additional statistical information and
necessary energy context information. The parameters and counters on this page
are actually set up in the ServicePower Setup section using the Configure
Energy & Demand button below.
An explanation of all Status Summary terms follows:
 Started: This is the date and time stamp from the last energy reset
 Last start: This is the date and time stamp for the last metering reset. Total consumption
is reset.
 Up time: The total cumulative time the mechanism has been operational during the cur-
rent period (since last start).
 Down time: The total cumulative time the mechanism has not been operational during
the current period.
 Availability: The percentage of time the system has been operational. This is important
because if this time exceeds a certain threshold, the data may not be considered reliable
 Energy (Metering) interval: The energy interval is the size of the window used in
computing demand (e.g. 10 minutes).
 External Sync: This function is currently fixed in disable mode.
 Sliding window: Information regarding the demand averaging system in use:
 Enabled: The demand is calculated using a sliding window averaging
system.
 Disabled: The demand is calculated according to stationary time points.
