4.5 POWER SUPPLY

■ 9.6 V rechargeable NiMH battery pack.
Line Voltage: (85 to 256) V / 50-60 Hz.

Average Battery Life: The operating time will be 15 days or 3 weeks based on a
10 min PI measurement.
Recharge Time:
Charging must be completed between (68 and 86) °F (20 and 30) °C
6 h for 100 % capacity (10 h if the battery is completely drained)
0.5 h for 10 % capacity (charge life: approximately 2 days)
NOTE:
It is possible to recharge the batteries while performing
insulation measurements provided that the values measured are higher
than 20 MΩ. In this case, the recharging time is higher than 6 h and
depends on the frequency of the measurements.
