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).

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
