Using AC Power and the Internal Battery
The aq Series Monitors come with an AC power adapter and a set
of four AA alkaline batteries. An optional sealed rechargeable
battery pack is also available. Call Metrosonics Sales Department
at 800-245-0779 for more information on this option.
Either AC power or internal batteries can be used to supply power
to the IAQ Monitor during tests; whichever best suits your needs.
The batteries are convenient for walkthrough surveys, while AC
power offers longer monitoring sessions. In addition to powering
the IAQ Monitor, the internal batteries also provide a back up power
source for programming and data retention.
The batteries MUST have a voltage of greater than 4.1 volts to
properly operate the IAQ Monitor. If the battery drops below 4.1
volts while the IAQ Monitor is operating, the IAQ Monitor will
automatically shut down and save the data already in memory and
the programming information for 30 days. This allows plenty of
time for you to change or recharge the batteries.
You can check the current battery voltage by turning on the IAQ
Monitor and pressing the arrow key (see “Viewing Information With
The Monitor” in Chapter 3).
NOTE: The IAQ Monitor draws power from the internal batteries in
order to maintain the clock and store programming information in
memory. If the IAQ Monitor will not be used for an extended period
of time, the batteries should be removed. New batteries should be
installed when the IAQ Monitor is used again.
Replacing the Internal AA Batteries
The procedure for replacing the AA batteries is very simple and can
easily be performed within seconds. The IAQ Monitor will maintain
its programming information and logged data during battery
replacement, provided that the replacement procedure DOES NOT
take more than 2 minutes.
The IAQ Monitor
MUST be turned off before removing the bottom
end cap. If the unit is inadvertently left on when the battery is
removed, all programming and data will be lost.
Follow these instructions to replace the AA batteries in the IAQ
Monitor. (be sure you have a new set of batteries ready before you
begin this procedure):
