1.4 Working with SpectroDens

Switching on and off
SpectroDens is switched on by pressing the green measurement button.
It is immediately ready to measure. In this state power consumption is very low.
If no button is pressed within five minutes, the device will switch off automatically.
Switching it on again with the green measurement button will show on the display the
last measurement done. There is no button to turn SpectroDens off.
Since hardware-version 2 the display is provided with backlight which turns on auto-
matically when the device is started.
Charging
The battery status is displayed as a battery symbol in the lower left corner of the
LCD screen, when the unit is turned on.
When the battery turns empty, the battery symbol starts to flash. In this state several
measurements still can be obtained; but it is time to put it on the charging console to
avoid a total discharge and damage of the battery.
Charging starts automatically by placing the device on the charging console. Please
keep the charging contacts on the console and under the device always clean.
If oxidized, use a special metal contact cleaner.
Five seconds after placing the device on the console the display will show a clock and
an animated battery symbol. When the symbol displays a full battery, the charging is
completed and the battery is fully charged. Completely charging an empty battery will
take approximately four hours.
SpectroDens has a regulated charging management. This means it will power-charge
an empty battery, so the device can be used again after a few minutes. On the other
hand, there is no overcharging of full batteries.You can park the device on the charg-
ing console when not in use. This way it is guaranteed to have always an operational
measurement instrument at hand.
Up to 10.000 measurements can be carried out with one battery charge.
