DM7276 Precision DC Voltmeter Introductory Video
The DM7276 Precision DC Voltmeter delivers superior measurement accuracy of 9 ppm (0.0009%), an accuracy level that is demanded by advanced applications such as aging tests of lithium-ion batteries. Other key features include contact check to maximize measurement reliability, binning and temperature compensation, making the voltmeter ideal for developing and manufacturing Li-ion batteries, electrical double-layer capacitors, electric vehicle components, and other next generation devices.
Key Features
- High-accuracy model with 1-year 9 ppm Accuracy
- Capacitance contact check (using built-in C-monitor)
- Supports global production with built-in variable power supply
- Built-in EXT I/O, LAN, and USB

Fully-Automatic Self-Calibration and Highly-Stable Voltage Reference
Internal voltage reference represents screened components that have passed Hioki's special in-house tests and undergone long-term evaluation before being embedded in the system. Combining this with HIOKI’s original fully automatic “Self-calibration” technology, we are able to offer a 1-year guaranteed 9ppm accuracy.
Measurement performance resistant to temperature changes and at high repeatability
The DM7276 is equipped with a measurement engine resistant to extreme temperature changes even outside product specifications
Simultaneous Temperature Measurement and Display Converted Voltage in Standard Temperature
The open circuit voltage (OCV) for lithium-ion batteries can fluctuate by several dozen μV if the ambient temperature fluctuates by even 1°C (1.8°F). For components with this kind of temperature characteristic, you can use the temperature compensation function to display a value converted into a standard temperature voltage from the registered temperature coefficient. This is a new approach made possible by the DC voltmeter DM Series, which can measure both temperature and voltage simultaneously.
