At the bottom of the DAILY text log screen, the time the maximum statistics were stored is shown,
whereas at the bottom of the HOURLY text log screen, the date of the capture is shown. Again, if for
some reason the year of the time stamp was less than 2011, the time/date will alternate between
INVALID and the time/date stamped along with that data and does not necessarily mean the data
itself is not correct. If the data is all zeros and the year is shown as 2000, the data is most likely
invalid and not correct or the logging memory has not been filled yet. This is why the Classic powers
up with the year 05/04/2003. It means that data was actually logged but the date was not set,
whereas if it is showing 00/00/2000, it will normally mean that the data is just zero and therefore
invalid data as well as invalid time and date.
The upper right corner of the text log screens displays a number from 1 to 380. This number shows
the index or position of the data in the 380 data log time slots. The most recently stored data has an
index of 1. Two data points ago shows an index of 2, etc. This index goes for either Daily History or
Recent History text log viewing screen.
NOTE: Accurate and complete data logging requires that the date and time be correct. Set date/time
in the MISC/TIME menu. For night logging (logs when Classic is Resting), set NITELOG to ON in the
TWEAKS menu.
Graphical Logging Display Modes
Both DAILY and HOURLY logging can also be viewed in a graphical manner. While in the text
viewing log screen, pressing the RIGHT SOFT key labeled "GRAPH" will bring up this view screen.
The HOURLY view is also available in the main status cycle of screens, changed by repeatedly
pressing the STATUS key, just after STATUS TWO screen. This is labeled as "SHORT TERM
HISTORY" in the STATUS screens.
A summary of the next STATUS screen will be shown while holding the STATUS key before releasing
it and entering that next STATUS screen. This also goes for the Recent History graph screen in
STATUS. Each data point shown in the graphical view screen is shown as a dot. There are a
maximum of 96 dots, appearing horizontally per screen with some information about each dot
shown on the left side of the screen. An individual data point can be selected for investigation by
moving a small, flashing once per second vertical cursor horizontally across the graphed data by
using the LEFT and RIGHT ARROW keys. The most recent data is shown on the right most side of
the first screen. The cursor first appears around 20 dots or data points from the right side of the
first screen (About 20 data points ago in history).
To scroll the data viewed one third of a screen to the left, hold the SHIFT key and the LEFT SOFT key
down and also tap the LEFT ARROW key. Each press of this combination of buttons will scroll the
graphical view horizontally another 1/3 screen. Holding the SHIFT key and RIGHT ARROW key on
the most recent data screen will push the cursor up against the right side and onto data point one.
Pressing the UP ARROW key will change the data viewed to the next category. For instance, in the
Recent History graph screen, the displayed data will change from power to input voltage, battery
voltage and kW-Hours. Pressing the DOWN ARROW key will bring the category of data back down
again. A very brief 5- or 6-character annunciator displayed in the upper left corner tells us what
category of data the graph is showing us. The number just below this 5- or 6-character descriptions
is the actual number in volts or watts or applicable unit of data displayed at that cursor position
