There are two Min/Maxlogs:
•Min/Maxlog
•Interval Min/Max/Averagelog
When any real-timereading reaches its highest or lowest value, the circuit
monitor savesthe value in the Min/Max log.Youcan use SMS to view and
resetthis log. For instructions,refer to the SMS online help. Youcan also view
the min/max val ues from the display. From the Main Me nu, select Min/Max
and then select thevalue you’d like to view, suchas amperes, volts, or
frequency.See “Viewing Minimum and Maximum Valuesfrom the Min/Max
Menu”on page 39 in this manualfor detailed instructions. The Min/Max log
cannot be customized.
Inaddition to the Min/Max log, thecircuit monitor has a Min/Max/Averagelog.
The Min/Max/Averagelog stores 23 quantities, which are listed below.At
each interval, thecircuit monitor records a minimum, a maximum, and an
averagevalue for each quantity. Italso records the date and time for each
interval alongwith the date and time for each minimum and maximum value
within the interval.For example, every hour the default log will logt he
minimum voltagefor phase A over the last hour, the maximum voltagefor
phaseA over the last hour, and the average voltagefor phase A over the last
hour.All 23 values are preconfiguredwith a default intervalof 60 minutes, but
you can reset theinterval from 1 to 1440 minutes. To setup,view, and reset
theMin/Max/Average log using SMS,see”Reading and Wr iting Registers ”in
the SMS online help.The following values are logged into the Min/Max/
Averagelog:
•VoltagePhase A–B
•VoltagePhase B–C
•VoltagePhase C–A
•VoltageN–G
•Current Phase A
•Current Phase B
•Current Phase C
•Current Phase N
•Current Phase G
•kW 3-Phase Average
