Description of the instrumentII - 18 SCOPIXDescription of the instrument (cont'd)Charging thebattery*Once the battery is located in its compartment, follow the external power supplystart-up instructions.• To speed up recharging of the battery, switch off the power to theoscilloscope by a long press on the ON/OFF button.• Battery fully discharged: during the first 10 minutes, the CHARGE LED of theexternal power supply flashes, indicating that the battery is slow-charging.The CHARGE LED then lights up when it switches to fast-charging.During the loading of the battery (after 15 min), the startup of theoscilloscope causes the premature stop of the load. It is possible to re-start the loading while disconnecting, then reconnecting the charger.The LED goes out when the battery is fully charged (approx. 2h30).Charging thebattery whileusing theoscilloscopeWhen the oscilloscope is connected to the mains via the external power supply, itis possible to perform slow-charging of the battery.The CHARGE LED of the external power supply lights up. Full recharging of atotally discharged battery then takes approx. five hours and a half. The LED goesout when the battery is fully charged.* Frequently recharging a battery when it is not fully discharged reduces itslife span.Powering theinstrument withthe batteryWhen the oscilloscope is powered by a battery, an charge status indicator isincluded in the display area of the current value:the battery is 100% chargedthe battery is 80% chargedthe battery is 60% charged, etc.this symbol indicates that there are only a few minutes more,so you are advised to recharge it or switch to the mains supply.The battery is totally flat and the screen is about to bedeactivated. You must either recharge the battery or connect theinstrument to the external power supply.If you change battery, a complete battery charge and discharge cycle (until theinstrument is automatically deactivated when discharging has finished) isessential to calibrate this indicator.To maintain the battery in good condition, use the oscilloscope at leastuntil the level before recharging.www.ShopAEMC.comShop for AEMC products online at: 1.877.766.5412
