• DC power and energy reference measurements in electrical metrology laboratories
• Calibration of DC power and energy measuring instruments
• Assessment of DC energy meter verification devices
• Traceability for DC energy metering programs

Every DC energy meter, whether it sits in a charging station, a battery system, or a DC distribution panel, traces its accuracy back to a laboratory reference. Choosing that reference means matching its range, uncertainty, and environment to the work the laboratory actually does.

The TH3900 belongs to the Tunkia family of DC power and energy standards, alongside the Tunkia TH3000 AC and DC power energy measurement standard and the Tunkia TD1300 DC standard meter. Laboratories use these standards to check DC energy meter verification devices such as the Tunkia TD1580 and Tunkia TD1575.

Because a reference standard is specified around the laboratory it serves, AV-TEK reviews your measurement scope, environment, and existing standards before proposing a configuration, and shares the full manufacturer specification at that stage.
