The 24V DC power converter and 12V auto-style power cord connect to the 3-pin socket connection located on the back of
the enclosure . A fully charged battery provides up to 9 hours of continuous operation before recharging is necessary .
At that point, the meter operates for only a short time more until it automatically turns itself off .
If the flow meter is to be used for extended periods of operation, the 24V DC line power converter or the 12V auto-style
converter can remain connected indefinitely .
To charge the internal Lithium-Ion Smart battery, apply power, using the enclosed 24V DC line power converter or auto style
power cord, to the flow meter for a period of 4 hours with the unit off . The flow meter has an integral charging circuit that
prevents overcharging . The flow meter can be permanently connected to an AC line power without damaging the meter or
the battery .
The Lithium-Ion Smart battery is maintenance free, but it still requires a certain amount of attention to prolong its useful life .
To obtain the greatest capacity and longevity from the battery, the following practices are recommended:
• When charging or using external power, allow for airflow to the instrument .
• The flow meter’s battery management circuitry does not allow the battery to become overcharged .
• The lithium-ion battery is rated for 300 cycles, but may last much longer than that . Cycle counts are shown in the
system menu .
• If the meter is stored for prolonged periods of time:
• Recharge the battery every 6 months and recharge before use .
• Store at room temperature . Extended exposure above 104° F (40° C) can degrade battery life .
• Do not expose unit to temperatures beyond those specified .
• Battery should only be replaced by authorized personnel .
• In the unlikely event that smoke, abnormal noise or strange odor is present, immediately power off the DXN and
disconnect all power sources . Report the problem to your device provider immediately .
Use wiring practices that conform to local codes (National Electric Code® Handbook in the USA) . Use only the power
converters that have been supplied with the flow meter . The ground terminal, if present on the converter, is mandatory for
safe operation .
