Description
Power supply
VIBSCANNER is powered by a rechargeable NiMH battery,
which is installed in the handle of the device. The battery is
charged by the VIBSCANNER Charger (VIB 5.420). During
the charging process, VIBSCANNER is switched off and the
battery remains inside the instrument. Reserve batteries
can also be charged outside the instrument.
What happens ...
... if VIBSCANNER is switched on and the battery
charger is connected?
> The charging process is interrupted and...
- VIBSCANNER is supplied with mains power.
- VIBSCANNER EX is supplied with battery power.
... if measurements are perfomed during charging?
> This can result in measurement errors.
... if the battery is removed longer than 10 minutes?
> VIBSCANNER loses the time and date setting.
What to do ...
... if VIBSCANNER is not in use for a prolonged period
(> 3-4 weeks)?
> Remove the battery and leave it connected to the
charger (does not apply to VIBSCANNER EX).
Charging the battery
Rechargeable batteries must not be charged in hazard-
ous areas!
• Open the protective cap on the battery.
• Connect the battery charger to the battery and to the
power supply.
Before charging, the battery should be discharged as much
as possible. The maximum charging time is approx. 6 hours
(approx. 10 hours for intr. safe battery).

Protective cap Level of charge
LED (red, green)
Operating state during charging
The charge level of the batteries is indicated by two LEDs:
• Red lights up: battery is being charged
• Green lights up: battery is charged
• Red flashes: battery is defective or initialization (only
beginning to charge; can flash for several minutes).
Description
Charge level of the battery
The charge level of the battery appears at the bottom right
of the VIBSCANNER display:
Level of charge
(black= battery full)
Even if the battery exhibits only a very slight memory
effect, it should only be charged when it is completely
discharged. Otherwise, the display of the charge level can
vary from the actual charging status after several ‘incom-
plete’ charging cycles and the following message appears:
Information: BATTERY LEVEL INACCURATE!
The battery level display may be inaccurate....

VIBSCANNER 11.2010
12
Description
In order for the display to show the actual charge level of
the battery again, proceed as follows:
• Leave the VIBSCANNER switched on until the battery is
almost fully discharged when the message appears:
Battery empty
If the message appears during a measurement, you
have approximately another 30 minutes time to termi-
nate your work and save the data.
• Recharge the battery again.
When the VIBSCANNER is switched on, the message
‘Battery level inaccurate...’ appears again.
• Discharge the battery again as described above, and
recharge it again.
Only when this step has been completed is the display of
the charge level correct.
Handling VIBSCANNER batteries correctly
1. Never deeply discharge the battery
If the battery is nearly empty, VIBSCANNER automatically
switches off to avoid deeply discharging the batteries.
Since a low residual current flows even when VIBSCANNER
is switched off, the battery should be taken out of the
instrument if it is to be stored for a lengthy period of time
and charged at regular intervals (1 month) to avoid a
complete self-discharge.
2. Charge and discharge the battery completely:
Repeated incomplete discharging/charging leads to a re-
duction of the battery capacity through the so-called
memory effect and to an imprecise loading status display.
However, this can be remedied by a number of complete
charging and discharging cycles (‘Battery empty’).
3. Store the battery in a cool place
The self-discharge of the batteries increases greatly at
higher temperatures. Therefore, the battery should be
stored as cool as possible (0-25°C) or, if the storage
temperatures are higher, it should be recharged more
often. Batteries that are not intrinsically safe should always
be connected to the charger during storage (‘conservation
charging’)

Program structure
The VIBSCANNER application program is graphic-oriented
and menu-driven.
Graphic-oriented
a) The measurement tasks are started via corresponding
icons on the screen.
b) In the basic version the measurement tasks are stored in
two screens that are opened via the screen icon Σ1or Σ2:
The Σ1 screen contains measurement tasks for overall
vibration and other important variables (see page 16).
The Σ2 screen contains measurement tasks for overall
vibration that are optimized for specific machine types
and RPM ranges. The first line depicts the machine types
and the left column defines the RPM range (see page
34).
c) A corresponding selection screen exists for the optional
program modules (details of the optional modules are
given in the ‘VIBSCANNER - FFT analysis and balancing’
operating manual - VIB 9.664.G).
Measurement tasks are selected
via icons.
The selection screens are
opened via the screen icon at
the top left in the order they
appear.
