Maintaining your Data Loggers
Replacing Batteries
The Smart-Vue Pro Duo/Quatro data logger runs on batteries
and/or AC power (via an adapter plugged into the USB port).
Batteries are not installed prior to delivery.
To replace batteries:
Follow the below sequence to replace with new batteries and
ensure that the battery counter is reset by pressing Reset
Battery in SVP Quatro Menu. See
Pro Duo/Quatro Battery Counter
Note:
The battery indication does not provide the battery level
from the actual battery. There is no electronic component in
the data logger that measures the battery level form the actual
battery. The battery indication displayed is the battery level
which is calculated by the data logger software based on
usage and has a dependency on the battery counter reset.
Note:
Battery Reset is performed by the user when they
replace new batteries in the Smart-Vue Pro Duo/Quatro and
Battery Reset must be performed only when replacing old
battery by new battery. When the battery counter is reset, it is
assumed that a new battery is used which implies a 100% full
battery. If this step is not performed correctly or if the battery
is defective, then the battery counter may be invalid.
1. Remove the data logger from its mounting bracket if
necessary. If possible, keep the device plugged into the
AC (USB) power source.
Figure 59. Optional: plug data logger into AC (USB)
power to avoid losing data
2. Use a manual screwdriver to remove the screw from the
battery cover on the back of the data logger by turning
the screw counterclockwise
(1)
, then push the plastic tab
open and remove the battery cover.

3. A single battery will ensure continued operation so you
can replace the other battery without interrupting data
logging:
•
Remove one used battery from the data logger and
replace it with a new one, making to respect battery
polarity (see image printed inside battery slot).
CAUTION: Data in data logger memory is
lost if you remove both batteries.
If data
logging is currently running, do not remove both
batteries at the same time. A single battery is
sufficient to maintain power during the change.
We recommend plugging the Smart-Vue Pro
Duo/Quatro data logger into AC (USB) power
when changing batteries to avoid any risk of data
loss.
CAUTION:
When replacing the batteries, ensure
both the batteries are replaced with
NEW
batteries.
