DATA
DATA: The DATA mode is used to recall key
historical information about the battery (battery
banks).
To access the DATA mode:
1) Select Battery #1 or #2 to review its data.
2) Press and hold the SET UP button until the green LED begins to flash then release the
button.
3) Now press the (blue) DATA button, each time you press the DATA button a new
piece of data is displayed. You may also hold the button down to scroll through the
following data:
CEF (Displayed as E99): The Charging Efficiency Factor (CEF) is displayed. A display
of E99 indicates a 99% CEF. This number sets the rate at which Amp-hours are counted
back up during charging. This is an Amp-hour CEF, not KWhr efficiency. The Default
setting is 87% for Type 1 (Liquid) batteries and 90% for Type 2 (Gelled) batteries. NOTE:
If the CEF display has a "u" in front of it, this means the CEF has been selected by the user.
See Function F06 for details. The CEF of a battery typically remains fairly constant until
end of life. A sudden drop in the CEF indicates a battery failing or a charging problem.
#CEF Recalculations (Displayed as +I999): This is the number of times that the battery
has been discharged more than 10% and then recharged until the Charged Parameters have
been met. May be considered as the number of charge/discharge cycles the meter has
recorded since its last RESET to factory defaults. This is useful to evaulate the cycling
performance of your battery system.
Deepest Discharge (Displayed as -i999): Shows the deepest discharge in Amp-hours
recorded by the meter since its last RESET to factory defaults. Very deep discharges
indicate battery abuse.
Average Discharge (Displayed as i999): The running average of all discharges as an
Amp-hour value since last RESET to factory defaults. The average discharge level should
normally be no more than about 50% of declared capacity.
