Volt/mA calibrator for calibration and accuracy testing of energy meters, instrument-class transducers and multi-purpose measuring instruments.

ACCURACY CLASSES: 0.01, 0.02 or 0.05

DESCRIPTION:

The Calmar-S is a volt/mA calibrator designed for:

automated calibration and accuracy testing of Electric power meters with pulse output (see MTS-ME)
calibration and accuracy testing of instrument-class transducers of electrical values into DC current or voltage signals
calibration and accuracy testing of multipurpose measuring instruments with DC current and voltage measurement channels
