15.2 External DC input (battery charging)
All SPECTRAN RF measurement devices contain a
high-performance battery package which is already
installed in the unit.
However, this battery is not yet
charged due to safety reasons
. Please charge it
with the included charger. For this, connect it to your
usual mains and plug the small phone jack into the
DC input on the SPECTRAN.
Now turn OFF your
SPECTRAN
and the battery pack will be automatical-
ly charged. Full charge is reached after about 24
hours for the standard 1300mAh battery, and about
36 hours for the 3000mAh version.
Operating with an external power supply:
As described above, the DC input is suitable for charging the internal battery
pack. However, it can also be used for operating SPECTRAN independently of
the internal battery pack.
You can also connect other
DC power sources
from
8V to 12V max.
, by using
a 3,5mm phone jack. Polarization of the jack needs to be as follows:
The
inner conductor
must be “+”, the
outer conductor
must be “-”.
Using our optional car power adapter (see price list), you can also operate
SPECTRAN devices in your car.
Should you wish to operate SPECTRAN via the wall power supply, please note
that the power supply will cause additional interference.
This may lead to mis-
measurement in extreme cases
.
Please note that the included switching power supply operates between
55kHz and 65kHz (60kHz Center plus 10kHz Spread Spectrum).
All cables/devices used for connection to the external DC input must supply a
DC voltage between 8 and 12V via a standard 3,5mm phone jack (inner con-
ductor PLUS, outer conductor MINUS).
