MTS-MONO-ME 1.120

National Registry Number 89778-23

Portable test system

The MTS-MONO-ME 1.120 is a compact portable test system designed for accuracy testing/verification/calibration of smart energy meters and measuring transducers.

It combines three instruments in one: a reference meter, a current and voltage source and a volt-mA calibrator/error calculator.

Accuracy class: 0.05

Purpose

The MTS-MONO-ME 1.120 is intended for verification and calibration of:

	single-phase smart energy meters with power quality measurement function (accuracy class 0.2S) Test scheme
	single-phase measuring transducers with unified DC current and voltage signals Test scheme

Application

The MTS-MONO-ME 1.120 can be used both in the laboratory and field conditions.

With the MTS-Service software, testing is performed automatically including generation of test reports (complete with environmental data according to ISO/IEC 17025-2009 as well).
