POWER SUPPLY
The tester can be power supplied by internal Li-Ion accumulator (2000mA*h,
3.7V), as well as by external direct current source with approximate voltage
4.5...7V and current load not less than 500mA connected to micro-USB input of
the tester by means of standard connector (e.g. of PC USB connector or network
USB adaptor).
Once external power source is connected – the Tester is charging, no difference if it
turned ON or OFF.
If the Tester's accumulator is discharged, connected external power source will
give the drain to the Tester operation, charging of accumulator is effected
residually.
Maximum current consumption from external power source is 500mA, which is
determined by charging controller.
Charging time makes 4.5 – 5 hours for fully discharged accumulator.
