Measurement error
If a measurement is not available or out of range, it is displayed as "EEEE" on WM50 display and as "--" on UCS. See
"Troubleshooting" on page 36
Average value calculation (dmd)
The system calculates the average value of electrical variables in a set integration interval (15 min by default). The average value
will not be available if the variable measurement is out of range. By default, the integration interval is calculated from when the
analyzer is turned on. To guarantee calculation alignment, it can be synchronized using the internal clock. In turn, the internal clock
can be synchronized with an external reference via digital input (i.e.: from the electric manufacturer's device).

Note: the single channel and load variable can be selected via
UCS to manage alarms with differentiated thresholds for each
channel/ load and view daily minimum and maximum values
and real-time minimum, maximum and average values (dmd).
Minimum and maximum values are calculated only
considering valid values and not out of range values.
Note: a Modbus protocol table can be set from UCS to
customize and facilitate TCD12 variable reading. See
"Download" on page 1, "Modbus communication protocol" for
further information.
