6.5 V Battery Test Symbolic display Battery Saving Circuit Display illumination can be deactivated. The test instrument is switched off automatically 10 to 60 seconds after the last key operation. ON-time can be selected by the user. Service Life For RISO, RLO, IB: 3000 measurements with one set of batteries (alkalinemanganese) with 10 s ON-time and automatic device shutdown after each measurement For U/f and T/Frel: 5 h (same conditions as above) Safety Shutdown The instrument is switched off if supply voltage drops to below the specified level, or it cannot be switched on. Charging Socket Rechargeable batteries can be recharged inside the instrument by connecting the NA0100S charger to the charging socket. Overload Capacity RISO 1000 V continuous, 1200 V for 10 s RLO und IB Electronic protection prevents the device from being switched on if interference voltage is present .
