Description
DM7276 DC Voltmeter for High Precision Measurement
The DM7276 Precision DC Voltmeter is engineered to meet the growing demand for ultra high accuracy DC voltage measurement in advanced energy and electronics applications. Offering a guaranteed one year accuracy of 9 ppm, this voltmeter is specifically suited for lithium ion battery aging tests, where even microvolt level variations can impact performance evaluation.
Accuracy and Stability
At the core of the DM7276 DC Voltmeter is a highly stable internal voltage reference built from carefully screened components that have passed Hioki’s long term reliability testing. This reference is paired with Hioki’s proprietary fully automatic self calibration technology, allowing the instrument to maintain exceptional accuracy without manual intervention. As a result, measurement performance remains stable even during extended operation and changing environmental conditions.
Temperature Compensation Capability
Lithium ion batteries and advanced capacitors are highly sensitive to temperature changes. The DM7276 DC Voltmeter addresses this challenge by measuring voltage and temperature simultaneously. Using registered temperature coefficients, the instrument converts measured values into standardized temperature compensated voltages. This capability allows engineers to evaluate open circuit voltage behavior accurately, even when ambient temperature varies by as little as one degree.
Reliability in Production Environments
To ensure reliable measurements in automated systems, the DM7276 includes a built in capacitance contact check using a C monitor. This feature verifies probe contact condition before measurement, reducing errors caused by poor connections. With built in EXT I O, LAN, and USB interfaces, the voltmeter integrates seamlessly into automated production lines and test systems worldwide.
Next Generation Applications
From electric vehicle components to electrical double layer capacitors, the DM7276 DC Voltmeter supports a wide range of next generation device testing needs. Its resistance to temperature variation, high repeatability, and flexible communication options make it a trusted solution for both research laboratories and mass production environments.
