Technical notes
VIBXPERT is a precision instrument and should be treated as such.
Storage
Use the VIBXPERT carrying pouch for transporting VIBXPERT and
for making on-site measurements. If VIBXPERT is not used for
lengthy periods, stow the measurement instrument in the pouch
and connect it regularly to the mains to avoid the battery from
completely discharging.
Make sure that
- the storage location is dry
- the measurement device is not stored near electronic equipment
which can generate strong electromagnetic fields.
- the measurement instrument is not exposed to temperatures
above 70°C / 156°F or under -20°C /-4°F.
- the humidity is not more than 90%.
Cleaning
If lightly soiled, the carrying case and the housing can be wiped
with a damp cloth. In cases of more stubborn soiling, use a
household cleaner.
The display is protected against damage by a scratch-free
transparent film. Use a soft dry cloth to clean the film. If necessary,
the protective film can be ordered from your PRÜFTECHNIK
representative.
Never use solvents or other strong cleaning agents
Maintenance
Various factors such as aging or temperature can cause an offset in
the analog electronics. This offset should be compensated every two
months. Details are given on page 2-29.
To guarantee the high measurement accuracy of the device,

VIBXPERT requires accuracy checks every two years. The
respective date is indicated on the colored sticker on the rear of
the measurement instrument. A couple of months before the next
accuracy check a warning will appear on the display when the
instrument is switched on. Send the device to your PRÜFTECHNIK
representative.
Before you send the unit in for repairs or calibration, transfer the
measurement data to the OMNITREND software. Afterwards, conduct
a backup. For data backup, use the program VIBXPERT utility (p.
6-5f).
For safety reasons, do not send units if the battery is obviously de-
fective or if you suspect a defect in the battery!
