PRE-OPERATIONAL CHECK
OSP series
portable thermometers are powered either by four alkaline or by Ni-MH rechargeable batteries (optional).
The external battery charger, supplied as a standard , is set for 115Vac power source.
Before using the instrument carefully verify the nominal voltage value of the charger with the available mains power line.
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%.
In case of “low” battery conditions (voltage lower than 4.6 V) the display will show the appropriate symbol. A battery
symbol means that the battery package has enough energy for about 20 minutes operation. In this condition the
instrument batteries must be recharged.
