MONITOR FUNCTIONS
Please also refer to the one-page summary of features in center of this manual.
The small blue legends indicate Setup functions described later.
BATTERY SELECT
The battery to be monitored is
selected by pressing the #1 or
#2 switch. A Green LED indi-
cates which battery is selected.
("Battery" may be a "bank" of
batteries.)
VOLTS
When the VOLTS switch is pressed, the voltage of the selected battery is displayed.
The measurement range is from 8.5 V to 50 V. The resolution is 0.05 volts. See page 39
for power supply specification.
AMPS
When the AMPS switch is pressed, the current flowing into or out of the selected
battery is displayed. Amps being consumed are displayed as a negative number. Charging
amps are displayed as a positive number (no sign). The resolution below 42 amps is 0.1
amps. Above 42 amps the resolution is 1 amp. The range is from -500 A to 500 A. Over-
range is indicated by OL.
Ahrs
When the A hrs switch is pressed, the amp hours (Ah) consumed from the battery
is displayed as a negative number. During discharge the negative number will grow as amp
hours are consumed and the meter counts down. During charging, the number of amp hours
consumed will decrease as the meter counts back up toward zero. The range is + 9,999Ah.
If the battery continues to be charged after the meter counts back up to zero,
overcharge amp hours are accumulated and displayed as a positive number. If there is an
accumulated positive number in the display when discharging begins, the meter automati-
cally resets to zero and begins counting down. See Overcharge Amp Hours on page 16.
The meter also automatically resets to zero after a discharge/charge cycle that
satisfies the conditions for a recalculation of the Charge Efficiency Factor (CEF). In other
words, if the battery is discharged 10% and then recharged until the charged parameters
have been met, the amp hours consumed display is reset to zero.
TIME
When the TIME switch is pressed, the time which the load can continue to be run
is displayed. The display is in hours with 0.1 hours resolution. The unit may be set up to
calculate the time remaining based on the instantaneous current, or a rolling average of the
last 4, 16, or 32 minutes. The time remaining function also takes into account the magnitude
of the discharge current (see pages 24–27). The maximum time remaining is 255 hours.
If you see this display, it means that the current being consumed could be supplied for
more than 255 hours. During charging, current is a positive (unsigned) number and the
