Installation and Operating Manual
Duo Storage Battery Tester S
12 V
Order No. 1245
The Votronic Duo Storage Battery Tester is designed for the voltage metering of vehicle and board
battery in high-quality campers and fire-fighting and intervention vehicles.
Please read the mounting instructions and operating manual including the safety regulations
completely prior to starting connection and start-up.
The compact and robust unit displays two voltage rates, either
of the board battery or of the starter battery. It represents
clearly the most interesting range of the battery voltage, from
total discharge up to maximum charging voltage.
The luminous spot display supplies a quite precise display of the
battery voltage rates, since also the intermediate values are
clearly legible due to the different brightness of the adjacent
luminous spots. At the push of a button, the voltage of board or
starter battery can be selected, or the display can be switched-
off. In case of low battery voltage rates, red pilot lamps indicate
that battery recharging is required.
The Duo Storage Battery Tester S is executed as panel version
matching to the VOTRONIC modular system (identical height 85
mm). The combination with units of the VOTORNIC modular
system, such as the tank displays S, the LCD displays S, as well as
the switch panels and fuse panels S, is a useful application. The
units can be combined perfectly with regard to appearance, and
their installation is easy (see example modular system).
Installation:
Choose a well visible and easily accessible location in the living area for installation of the unit. The installation place in
the front panel of the furniture should be chosen in such a way, that the contrast of the display be not hindered
(sun light).
The electronic system’s small mounting depth of only 14 mm allows flush mounting into commercial furniture boards to
ensure, that an optimum installation place can always be chosen without losing precious storage space.
The clear opening of the furniture cutout should be slightly larger than the assembly dimensions of 29 x 62 mm to ensure
safe alignment of the unit’s front panel.
If several VOTRONIC units are applied, use the delivered jig for marking. The drilling jig facilitates positioning
and reduces the expenditure of installation, since time-consuming measuring for alignment is not required.
The rear cutout opening should be covered with electrically nonconducting material (e. g. plastic plate, poplar
plywood, or similar material) to ensure full utilization of the storage space, which might be located behind
Make all electric connections, place the Duo Storage Battery Tester S centrically in the cutout, and use the delivered
screws for fastening.
