9. Instrument Maintenance
In this chapter are presented maintenance guidelines to keep your instrument in good
condition, so that you have a reliable companion for many years to come.
For the batteries to last as long as possible charge them fully at least once every 3
rd
month,
even though you have not used the instrument. Normal battery life is 2 years after that the
instrument operation time will start being gradually reduced.
Store the instrument in a cool place away from direct sunlight (the instrument case
delivered with the instrument is an ideal storing place). The storing temperature should not
exceed 80 degrees Celsius or go below -30 degrees Celsius.
Clean the instrument with a mild detergent and a clean cloth.
It is good practice to always wipe the transducers and Tachometer holding magnets clean
before using them and when placing them in the case after use.
The connectors and cables for the VIBER X5 MkIII™ have been selected to be as robust and
reliable as possible, even so it is good practice not to bend the cables or pull them when
loosening the transducer magnet.
To make sure your instrument continues to show accurate readings it should be regularly
calibrated.
9.1. Battery Management
The instrument has two battery packs built-in:

Backup battery. A small 3V battery for the Real Time Clock; the expected life of this
battery is 10 years. If Date and Time are always reset to the default values when you
stop/start the Instrument means that the backup battery should be replaced.

Main battery pack
The main battery pack capacity and type may be variable depending on instrument version;
standard is 66.6 Wh, Li-Ion.
In each menu, the window header displays graphically the battery status (by the color of
the battery symbol) and remaining capacity (by the filling grade of battery symbol). Also it
displays the charging status if the charger is connected (see Status Bar section on
Instrument description).
Whenever the symbol is yellow or red the battery should be charged as soon as possible.
The Instrument can work with a very weak battery without the risk to corrupt the
measurements. The built-in battery controller keep watch on the available power and
automatically stops the Instrument, when the power in too weak to assure the
measurement integrity.
When you work with a weak battery, the battery life can drop dramatically.
A full charge process may take 3 to 5 hours, depending on the battery’s total capacity.
The charger icon can be:
Green (the battery is normally charged)
