11.2 Data Points

Data recorded can be selected for logging. For P1, P2, or P3, the data recorded
takes the name chosen for the specific temperature probe. If P1 or P2 or P3 is
chosen as LTCDIFF, the data recorded is the differential between the LTC tank
temperature and the Top Oil probe. All other temperature points are recorded as
the absolute value of the measured temperature.
The load current reported is the average or demand logged for the period
between samples. If a Time Base of 15 minutes is selected, the load current is
the average value over 15 minutes. For Time Base settings less than 16
seconds, the load current reported will be the actual load current.

11.3 Setting the Time Base

Time Base can be entered from 0 to 9999 seconds. Setting the Time Base to
zero will reset the log and no records will be logged. Changing the Time Base will
