Power Supply
• 9.6V rechargeable NiMH battery pack
• Line Voltage: 85 to 256V / 50-60Hz
Minimum Battery Charge Life (per NF EN 61557-2)
Test Voltage

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