PRE-OPERATIONAL CHECK
The instrument is powered by four Ni-Cd rechargeable batteries.
The external battery charger, supplied as standard, may be ordered for either 110-120 Vac or 220-240
Vac power source.
To modify the charger's power voltage follow the instructions in par. 8.2.
Before the first use of the instrument carefully verify the nominal voltage value of the charger; in case of
modification do not forget to correct the pertinent label.
The instrument should be used in environments where the temperature does not exceed the specified
limits (from –5°C to +50°C) and where the relative humidity is lower than 95%.
I n 0 . 0 0 V
In case of "low" battery condition (voltage lower than 4.5 V
±
0.1 V) the display will show the appropriate
symbol
An empty symbol means that the battery package has enough energy to operate for 30 minutes
operation.
A black symbol means that batteries charge is below the minimum acceptable level : operation of the
instrument is no longer possible.
In this condition the batteries must be recharged.
