Reference Standards

The CALPORT 300 is a accuracy class 0.05 Reference Standard and an universal test system for the comprehensive investigation and commissioning of all components of a modern metering installation.

The CheckMeter 2.1 Portable Working Standard is a single-phase portable electronic meter test unit in accuracy class 0.2, used for testing single phase electricity meters on site.

The CheckMeter 2.3 genX Portable Working Standard is a three-phase portable electronic meter test unit of accuracy class 0.2, used for testing single- and three-phase meters on-site. NEW: If only single-phase meters are to be tested, the CheckMeter 2.3 genX can be ordered with a single-phase user interface and a single-phase 120A current clamp to simplify operation.

The K2008 is a three-phase comparator of accuracy class 0.005 (50ppm) with direct voltage and current inputs. It has been designed for universal laboratory and test applications and is intended for checking and the calibration of reference standards for electrical power and energy. In addition, it can be integrated into meter or reference standard test systems of highest accuracy.

The PWS 3.3 is a combination of a three-phase Portable Working Standard of accuracy class 0.05 or 0.1 and an IEC 61000-4-30 Class A compatible Power Quality Analyzer with 3 voltage and 4 current channels.
