NEW"BATTERY REMINDERS"
Make good battery care easier: shows when recharging should occur, or battery
voltage gets too low. It's important to periodically fully charge lead acid
batteries to keep them in good condition. Program the desired maximum number of
days(1-60) between full chargings. Then, if the batteries exceed that time
without being fully charged the BATTERY REMINDERS lamp will occasionally blink,
and the display will flash "Ch. F", (as shown on the label) every 5 seconds to
explain the reminder. Similarly, program in desired number of days (1-250)
between battery equalizations and the TriMetric will remind you when to
equalize. (When equalization is accomplished you'll need to reset the "days
since equalized" data so it will remind you again the next time). Program in the
desired value of "lowest battery voltage" and the lamp will flash when battery
voltage falls below that voltage. You can disable any or all of these.
How a shunt works: A shunt is
necessary in order to measure amps and amp-hours with the TriMetric battery
monitor. A shunt is an accurate, very low resistance resistor which is placed
"in line" with the wire carrying the current to be measured. With the TriMetric,
it is usually placed in the negative wire from the battery bank, such that all
the current going into the battery (charging) or out (discharging) must pass
through it. Connected in this way it will be set up to monitor "net" amp-hours
in and out of the battery. (It also could be placed in series with the negative
wire coming from a solar array--or other charging source--in which case it would
measure only the solar array current, if that were desired--to show total solar
"amp hours" production.) The shunt needs to be placed near the batteries; since
these wires carry very high currents the wires from the batteries must be kept
short to minimize electrical losses.
