The battery pack with two 2 battery slots enables measurements without mains power. A TEKBAT-01 battery (lithium-ion, 6700 mAh) is already included in the delivery.
With one battery, the oscilloscope can be operated continuously for about three hours and with two batteries in the battery pack for about six hours. An on-screen icon and a battery status menu show the remaining battery power. The batteries are charged when the device is supplied with mains power. Alternatively, you can charge the batteries with an external charger (sold separately).
All oscilloscopes of the 2 Series MSO (MSO22 and MS24) support the installation of the battery pack.
