Chapter 5 Maintenance
Cleaning
Clean the Bird Digital Power Meter and its display with a soft cloth dampened
with mild detergent and water only. Clean sensors with a dry cleaning solvent
that leaves no residue.
Battery Maintenance
Charging Batteries
Fully charged batteries provide about 20 hours of continuous operation with the
Bird WPS, 50 hours with other sensors. Charging time is typically 5 hours using the
AC adapter. The batteries charge whenever the DPM is connected to AC or DC
power sources, using either the AC Mains adapter or the automobile cigarette
lighter adapter. When the external adapter is connected, the battery level indica-
tor will blink until the battery is fully charged. When using the internal batteries,
the indicator will be on continuously and the black bar will show the battery
change remaining. The unit will charge with its power turned either on or off.
Note: For optimum battery life, only charge the batteries after the
battery level indicator empties completely and begins to blink.
Prolonging Battery Life
To prolong battery life and optimize the accuracy of battery charge displays:

Charge the battery while the DPM is plugged into external power
through the AC adapter.

Charge it fully before turning on.

The battery charges whether the DPM is off or in use, but the battery
charges faster while the DPM is off.

Charging may be delayed if a battery is new, has been unused for 2
weeks or more, or is much warmer or cooler than room temperature.
CAUTION
Do not use harsh or abrasive detergents for cleaning.
