Operation manual
After calibration on the 5 mm for a single-crystal transducer or 25 mm for a double-
crystal transducer the determined velocity value in the instrument is shown on the
display.
The determined velocity value by the calibration procedure is not saved in the device
memory! Notice the velocity value and manually set it in the instrument if needed!
The maintenance of the instrument includes cleaning it from dirt and dust and recharging
the accumulator.

Maintenance
1.4.1
Accumulator battery
The rechargeable battery of the instrument is designed for operation over a wide range of
temperatures. The battery capacity decreases at negative temperatures. The capacity is
lower by approximately 15% than at normal temperatures.
If the battery is almost dead when the power is on, its state will be indicated by the
blinking unshaded battery symbol. The instrument will automatically switch off when the
accumulator battery is dead.
The rechargeable battery has built-in protection against overcharge, over-discharge,
excess current, and temperature.
The rechargeable battery is designed for the entire warranty period of the instrument
operation.
The rechargeable battery shall be replaced by the service centers only.
Replacing the battery by the operator immediately voids the warranty for the instrument!
1.4.2
Recharging the accumulator
The accumulator is charged via the external charger or from the PC via USB.
When the charger is connected to the instrument, the battery filling sign starts blinking.
During the charging process, the blinking symbol "moves" to the top of the battery sign.
The period of charging depends on the discharge level. The full charge takes about 4-5
hours. Repeated recharge is allowed.
One can use the instrument during charging. In this case, the charging time will be 2-3
times longer.
Don't store the instrument with discharged battery to prevent its functional loss!
