Mode 1: DC 12 V Input
The DL can be driven directly from an in-vehicle battery.
Mode 2: External Battery Drive
The DC power model yields approximately 2 hours* of operation using the battery box (with internal charger). Auquired waveforms are unaffected by the power supply noise.
Mode 3: AC Input
The battery box acts as the AC adapter when an AC input is available. You can measure signal continuously even when the power supply experiences trouble such as a power failure or voltage drop.*
*The operable time varies depending on usage condition.
