OPERATION
To ‘wake up’ a battery powered meter, you may need to
hold the up arrow for 5 seconds and release. If the meter
does not wake up on the first attempt, repeat the 5 second
hold.
The AG3000 meter can come configured with one 7.2V ‘D’
size replaceable battery pack. In this configuration, the
only option/output is the scaled pulse output which comes
standard. The scaled output for the battery powered
option has a maximum pulse rate of 150 pulses/second.
Be sure to set your P value such that the meter will function
properly over the flow range in your application. The
sample rate of the meter is user selectable through the
SAMP tab in the meter’s sub-menu. Sample periods of
1/5, 1/3, 1, 3, 5, 15, 30, and 60 seconds can be selected.
(A sample period of 5 seconds—5 year battery life—is the
default.)
Larger sample periods will yield longer battery life but
slower response time. Care must be taken to select a
sample period that is suitable for your application. See the
table below for the expected battery life as a function of
sample period.
DAMP Settings for Battery Units
If SAMP (sample period) is set to less than one second, the
DAMP value represents the number of seconds (plus one)
used in the rolling average for the display. For example, if
DAMP is set to four, then when the meter begins to show
a flow rate, the rate displayed is the average of all the
readings taken in seconds
one through five (4 plus 1).

*Based on 75% battery capacity at room temperature with
no option cards installed.
NOTE: If a large percentage of the meter’s life will be spent
below 0.5 meters/second and above cutoff, battery life will
be reduced.
Battery Powered Units
A power indicator is displayed in the lower left of the main
display window.
Any meter that was configured to be powered from an
external power source will display a power plug icon when
running on external power. If the connection to external
power is lost, the meter will switch to the backup battery
and the power icon will switch to a battery symbol.
All base model meters configured as battery powered (BX)
units will only show the battery icon whether running on
battery or external power and will always operate with all
the power saving features of a battery powered unit.
OK
on the battery indicator means battery voltage is above
6.4 volts.
LO
on the battery indicator means the battery is low and
should be replaced soon.

Power Indicators
If SAMP (sample period) is set to one second or longer,
the DAMP value represents the number of sample periods
(plus one) used in the rolling average for the display. For
example, if SAMP is set at three seconds and DAMP is set to
four, then when the meter begins to show a flow rate, the
rate displayed is the average of samples
one through five
(4 plus 1). Note that depending on the settings selected,
it may take up to a minute for the displayed rate to take
full advantage of the DAMP filter. When starting with an
EMPTY PIPE it may take at least 30 seconds to register any
flow.
