3.1

Power Supply

The PROMAX-27 is a portable instrument supplied by a built-in Li-Ion battery.
Before taking any measurement, we must ensure that the battery is charged.

3.1.1 Charging the battery

The instrument is supplied with a mains adapter in order to power or charge the
instrument.
There are two situations that can arise in the battery charging process:
1) Stopped Instrument: When connecting the external power it will start a rapid
charging cycle, whose duration will depend on the battery status. It will take three
hours for a discharged battery. The charging indicator on the front panel [10] will
remain lit in amber colour during this period. At the end of charging and in full
charge, the indicator will be green.
2) Instrument in operation: When connecting the charger, it will start a charging
process in a lower regime and therefore longer. At the end of charging and in full
charge, the indicator will change from amber to green colour.
