HOUR METERS PAGE
– Hour counters (meters) page simultaneously shows the following:
• Total hour counter (counts the power-on time of the device)
• Partial hour counter (counts how long a programmable condition lasts).
– To clear hour counters, it is necessary to access the commands menu.
– The hour counter (meters) page can be completely hidden if the general hour counter enable has been set to OFF (see hour counter menu).
TREND GRAPH PAGE
– The trend graph page allows to show the changes in the time domain of one measurement selectable among the following:
• Average equivalent voltage
• Average total active power
• Average total reactive power
• Average total apparent power.
– The default measurement is the Average total active power. To change the measurement, enter the dedicated menu parameter in the Trend sub-menu.
– It is possible to see, on the graph, the history of the last 96 values of the integrated measurement, each corresponding to a integration time interval.
– The default time interval is equal to 15 minutes, so the graph depth in time is equal to 24 hours.
– With the default factory setting, the trend graph shows the active power demand variation of the last day.
– The consumption data is lost when auxiliary power is removed from the DME device or when the settings in the setup menu are changed.
– When the maximum storing capacity is exceeded, the newest data will overwrite the oldest, so that the most recent data is always shown.
– The vertical full-scale automatically is calculated, depending on the measurement selected and the highest value recorded in the setup menu.
COUNTERS PAGE
– The counters page displays CNT1...4 counters.
– It is possible to count the number of times an input is activated, or a limit has been overcome, etc. The count condition is defined by Counter source
parameters.
– For every counter, it is possible to define a description and a unit of measure with a free text, for instance litres, kg, etc.
– It is possible to define a conversion factor between the number of pulse counts and the measurement shown on display. This function can be obtained by
specifying a multiply and a divide factor.
For instance, setting the multiplier k to 3, for every pulse count, the value shown will be incremented 3 times. If instead, a divider is set to 10, then the value
will be incremented by one only after 10 pulses have been applied to the input. With a combination of multiply and divide factor, any ratio between counts and
measurement can be achieved.
– If the counter has no divide factor, the screen will indicate the counter with whole-number digits; otherwise the counter will be displayed with two decimals.
– The counters can be cleared by means of commands menu or by means of the Reset source signal, defined by dedicated parameters.
2 - Vertical scale. Can be auto
ranging or fixed by the user.
