BAE 518 USB
3.3 Power supply
The
PAINT BORER
518 USB
can be operated in the field
– when it is disconnected from
the mains power supply. A 9-volt NiCd rechargeable battery (IEC No. 6F22) can be used
as the internal voltage source. Alternatively, a 9-volt non-rechargeable battery (alkaline
type IEC No. 6LR61) may be used.
The 9-volt battery is delivered in a separate package; it must be inserted in the black
plastic compartment on the right side of the instrument before you start using the
instrument.
3.4 Lighting and auxiliary lighting
The lighting intensity can be adjusted using the knurled dial on the digital microscope.
Turn the dial to adjust the lighting intensity from 0 to 100%.
In this way you can adjust the illumination for the particular sample.
We recommend using a medium setting so that the lighting intensity can be adjusted in
both directions (lighter or darker) if needed.
When working with certain coatings, it may be helpful to also use indirect lighting.
For additional sample illumination, a white light emitting diode (LED) with diffuse light is
used.
The green button at the rear of the instrument can be pressed to activate the side lighting.
When switched on, the LED can be adjusted to three brightness levels.
The charging socket for connecting the AC adapter is located on the rear of
the PAINT BORER. The charging time is 14 hours. Measurements may be
taken during the charging phase even when the battery is not installed.
Do not connect the charger while you are operating the instrument with the
battery!
We recommend removing the battery if you are always using the PAINT
BORER with the mains power supply. Otherwise, the battery can be over-
charged.
If you are using the instrument in the field (with the battery) sporadically,
then the battery may be left inserted. However, the charger should not be
permanently connected.
