Make sure that the batteries are inserted in the correct direction of polarity, there is a check-up drawing
located near the battery lid (below):
Study the overview of the battery compartment with the lid removed. The visible ends of the inserted
batteries should correspond to the ones in the drawing next to it
(+ being the one with the knob, - being the more flat-ended one.)
When packing up the RQ8000 to its carrying case for transporting the measurement system to another
location it is advised that the batteries should be removed from the battery slot and packed separately.
This way the measurement device does not switch on by accident resulting in lowered charge or drained
batteries and also the rechargeable batteries have a lower risk of self-discharging. This is also the
recommended procedure when the measurement device is going be left alone in storage for longer
periods of time.
With the batteries removed the real-time clock of the RQ8000 device loses the correct time in 2-4 weeks.
If this is the case it is recommended that the RQ8000 is connected to the PC before making a
measurement. By doing this the correct time is set and the timestamps of the measured files are correct.
3.2.2 Recharging Batteries
There are two methods of keeping RQ8000 batteries loaded and ready for measurement.
Every RQ8000 unit is supplied with an
external battery charger
which allows the user to recharge the
batteries outside the RQ8000 unit. When using an external charger to charge your batteries make sure
that you charge them to full capacity before inserting them back to the RQ8000.
Another method is the
USB charge
. When the RQ8000 is connected to the computer with a USB cable
the unit will recharge the AA batteries inside the unit. This recharge method is usually slower than
recharging with a separate, dedicated AA recharger but USB recharge is sufficient for keeping the
RQ8000 unit measurement ready for occasional measurements.
The usual measurement-recharge ratio for USB charge is 20% vs 80%, if the unit gets one hour of
measurement time it should get four hours of USB recharge to get fully recharged. Please check that
your RQ8000 unit supports USB charging before using this option.
NOTE
: Because of the USB charging function it is extremely important that the batteries are always
correctly aligned and
only rechargeable AA batteries are used with RQ8000 unit
.
If the batteries are not intended for recharging they may overheat or even explode and inflict
serious damage to the RQ8000 unit and its surroundings
.
