1. Amp Hours From "Full": Shows actual "net" amp hours removed from the battery from ±0.01 to ±9,999 amp hours. A flashing decimal point reminds you to multiply the reading by 1000 when the amp hour number exceeds 999. May be manually set to 0, or automatically when the "charged" criteria are met. (See information below on "How TriMetric determines that batteries are charged"). It is also possible for this display to measure only total amp hours produced by an energy source, such as solar array, or only load amp hours, by wiring the shunt in the desired current path.

2. How Many Days Ago Since Batteries Were Last Fully Charged: To prolong their life, lead-acid batteries shouldn't go too long between being fully charged. This display will show you how long since they last received a full charge-measures from 0.01 day to over 600 days. It's a timer that resets to 0.00 whenever batteries are fully charged (i.e. meets charged criteria as described below). If desired the "battery reminders" lamp will alert the user when this number exceeds a value programmable by user from 1 to 60 days. May also be manually reset with the "reset" button.

3. How Many Days Ago Since The Battery Was Equalized: "Wet cell" lead acid batteries should be periodically given an overcharge, called "equalization," to maintain their capacity. This is typically done every month or two. It's easy to forget when they were last equalized-this timer will keep track for you. Reads from 0.01 day to over 600 days. You will need to reset this number manually whenever you equalize the batteries. In addition, if desired the "battery reminders" lamp will alert you when this number exceeds a user adjustable "maximum equalize time" from 1-250 days.

4. Cumulative Battery Amp Hours: Records only discharging amp hours-displays to minus one million amp hours. (A flashing decimal point in the display tells you to multiply the reading by 1000). This function acts like an odometer in a car, to show how much total chemical change the battery has seen in its life. It's a "bottom line" number of total battery endurance and can be used to evaluate the life performance of the batteries and the care they've received at time of replacement of the battery set. This number stays in the TriMetric even if power is disconnected-in that case a maximum of the last 3.2 hours of data will be lost. When replacing the battery set the number to 0 by pushing "reset" button while this display is showing.

5. Maximum Battery Volts: Useful to check that the charging sources are charging to the voltage recommended by battery manufacture for longest life. Pushing the "reset" button when displayed to reset this display to the present battery voltage.

6. Minimum Battery Volts: Use this to check that batteries haven't been over discharged. Pushing the "reset" button when displayed to reset this display to the present battery voltage.
