2.7. Powering the device with an external power supply
In addition to charging the internal battery, the included power supply also allows to operate the
analyzer independently of the internal battery pack.
Other DC sources between 5V and up to a maximum of 5.9V can also be connected. A 3.5mm
jack plug must be used as the connecting plug. The connection plug has to be poled as the
following:
Internal pole „plus“ / external pole „minus“
An optional power adapter for a 12V connection available from Aaronia makes it possible to
operate the analyzer in the car.
Please note that by operating the analyzer with the power supply, additional interferences
are produced by the power supply, that might distort the measurement result. To avoid these
possibly occurring interferences for long-term measurements, we recommend to operate the
analyzer via a large, external battery. Those can (on average) provide power up to several
weeks. The power or battery packs from specialized electronics retailers are particularly ad-
vantageous. These usually have a regular 12 V connection and can therefore be operated with
the afore mentioned adapter cable.
CAUTION
: All cables / devices that you connect to the external power
connector of the SPECTRAN V5 must provide a direct current of 5V up to
5.9V. A standard plug with a 3.5 mm diameter must be used as the plug (

polarity MINUS)
Pay attention to the cable cross-section, because without an internal battery
the device requires around 18W of power. With an internal battery around
23W of power are needed because of the additional charging circuit
