As an evolution of the 701251 model, the 720252 expands the offset adjustment range compared to conventional digital oscilloscopes, allowing for the precise measurement of even the smallest changes in DC voltage and current in batteries or sensors. Its offset adjustment function can cancel a wide range of DC biases, such as battery voltage, DC voltage, and DC current.
Furthermore, it allows for the simultaneous observation of DC levels and microvoltage fluctuations, achieving resolutions as low as 1 mV/div in battery applications. Another significant improvement is its Hi Z (>1 GΩ) input impedance mode, which reduces the loading effect of the input circuit on a battery cell.

The 720301 module simplifies configuration by offering an all-in-one solution that correlates power consumption and generation with parameters such as temperature, strain, acceleration, and sound. It includes a direct voltage input and a current sensor input, integrating with the power analysis functions of the DL950 or SL2000 systems to ensure maximum accuracy in measuring DC and AC waveforms.
These capabilities are complemented by user-defined measurement periods (from 0.1 ms), cycle-by-cycle power calculations, and trigger functions based on power and harmonic parameters.

Development Context:
Energy storage infrastructure—from electric vehicle batteries to UPS systems in data centers—is growing rapidly due to electrification and the rise of artificial intelligence. Accurately evaluating these systems is key to moving toward a sustainable, low-carbon economy.
The 720252 module addresses the need for high-resolution fluctuation analysis in electric vehicle battery cells (~4.2 V), minimizing measurement impact thanks to its high input impedance.
The 720301 module, meanwhile, meets the demand for AC accuracy in high-speed data acquisition applications, simplifying the synchronized measurement of power, voltage, current, and physical signals.
