8.0 Using a BMK
When using the charge ef
fi
ciency’s
Auto
setting, the AH I/O value is recal-
culated after the battery has been fully charged (reaching 100% SOC) and
≥
0.5% of the battery capacity has been discharged. If the sense module is
disconnected from power, the displayed AH I/O value resets to zero.
Info:
The
AH I/O
display correlates with the
05B AmpHour Size
setting (under SETUP button) to help determine the
04B SOC
dis-
play. 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.

04F Reset AH Out
– This meter displays the total amp-hours removed
from the battery since it was last reset. This display can be used as a bat-
tery load indicator to help identify and monitor the battery load consump-
tion. The range is 0 to 65,535.0 amp-hours (0.1 amp-hour resolution).
To reset the amp-hours value to zero, press and hold the rotary SELECT knob for
>5 seconds when the
Reset AH Out
display is shown. After this display has been
reset, it will begin calculating and displaying new rAH out values. This display
automatically resets to zero if the sense module is disconnected from power.
• 04G Total AH Out
– This meter displays the total amp-hours removed
from the battery since the sense module was
fi
rst connected. This display
can 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 AHs (6,553,500 amp-hours). The displayed number resets to
0.0k when the sense module is disconnected from power.
•
04H Minimum VDC
– This menu displays the lowest battery voltage since
the last reset. The voltage shown on the display is averaged each sec-
ond, and is helpful when troubleshooting or detecting an over-discharge
condition. To reset this display, press and hold the rotary SELECT knob
for
fi
ve seconds while the
Minimum VDC
display is shown. After this
value has been reset, the display will begin monitoring and showing new
minimum DC input values. If the battery monitor is not connected or not
communicating, the display will show
“0.0”
.
• 04I Maximum VDC
– This menu displays the highest battery voltage
since the last reset. The voltage shown on the display is averaged each
second, and this allows you to check your charging system (battery
charger, charge controller, etc.) to ensure the charging voltage has been
attained. This display is also helpful when troubleshooting or detecting
if an over-charge condition has occurred. To reset this display, press
and hold the rotary SELECT knob for
fi
ve seconds while the
Maximum
VDC
display is shown. After this value has been reset, the display be-
gins monitoring and showing new maximum DC input values. If the
battery monitor is not connected or not communicating, the display
shows
“0.0”
