Operation
03 BM: Meters - This menu shows DC voltage, DC current and AH information
on the battery bank provided by the Battery Meter. The values for these meter
displays are updated each second.
Figure 5-2, METER: 03 BM: Meters Selections
• DC Volts - This meter displays the real-time battery voltage from 07.00 to
70.00 volts (± 0.02 volts).
• DC Amps - This meter displays the real-time charge current (amps into the
battery) or discharge current (amps out of the battery). Charging is shown as
a positive (+) number and discharging is shown as a negative (-) number. The
range is from ±0.1 to 999 amps, with a 1.0% accuracy.
• AH I/O - Amp-Hours In/Out; this meter displays the Ampere-Hours returned
to or removed from the battery. When this value is positive, it represents amp-
hours returned to the battery during any subsequent charging. A negative value
represents amp-hours removed from a full battery. The range is ±32768 AH.
When using the Chg Eff: Auto setting, the AH I/O value is recalculated after the
battery has been fully charged (reaching 100% State Of Charge) and ≥ 0.5% of
the battery capacity has been discharged. If the Sense Module is disconnected
from power, the AH I/O displayed value resets to zero.
Info: The AH I/O display correlates with the 03 Batt AmpHr setting (under
the SETUP button) to help determine the 02 BM: SOC display.
Info: AH I/O example; if you run a 10 amp load for three hours, the display
will show -30 AH. When you begin charging, the display will count from
-30 AH back toward 0 AH.
• rAH Out - Resettable Amp-Hours Removed; this meter displays the total amp-
hours removed from the battery since it was last reset. This display can be used as a
battery load indicator; to help determine and monitor the battery load consumption.
The range is 0 to 65,535.0 amp-hours (0.1 amp-hour resolution).
To reset the AmpHrs value to zero, press and hold the rotary “SELECT” knob for
more than 5 seconds when this display is shown. After this display has been reset,
the display will begin calculating and displaying new ‘rAH Out’ values. This display
automatically resets to zero if the Sense Module is disconnected from power.
• tAH Out - Total Amp-Hours Removed; this meter displays the total amp-hours
removed from the battery since the Sense Module was first connected. This display
can help be used as a battery service life indicator. The value is displayed in 0.1k
[or 100 amp-hours (“k” equals 1000)] resolution up to a maximum of 6,553.5k
amp-hours (6,553,500 amp-hours). The displayed number resets to 0.0k when
the Sense Module is disconnected from power.
