MTE offers a broad range of customized high precision test systems for customers such as utilities, meter
manufacturers and meter test laboratories.
The individual system components of a MTE meter test system are modularly developed and can be
combined in any order for testing of single- and three-phase meters with or without closed I-P links. This
modular design gives flexibility and enables MTE to provide the optimal customer orientated solution for
each single- or three-phase meter test system the customer requires to meet the changing needs in the
metering world.
MTE offers and respects the importance to upgrade existing test systems and provides solutions to
gradually replace existing systems with modern components.
Whatever the needs, wherever the customers, MTE has the innovative solutions and the focus to
contribute to the efficiency, profitability and quality of our customers.

It allows testing of single-phase meters with closed I-P connection using voltage isolation transformers.

Our focus is on executing perfectly the critical processes and steps for an efficient meter test system.For increasing the output volume, global meter manufacturers are asking for solutions to modernize their production processes and enhancing their efficiency.MTE´s Automatic Test Systems are the answer for a sustainable increase in the output (testing) volume of single- or three-phase meters while improving the productivity.Due to the comprehensive, flexible and modular system components, MTE is able to provide the optimal customer orientated solution for the volume production of meters.Whatever the needs, wherever the customers, MTE has the innovative solutions and the focus to contribute to the efficiency, profitability and quality of our customers.

The PTS 3.3 C portable test system consists of an integrated threephase current and voltage source and a threephase electronic reference standard of accuracy class 0.05%. Characteristic features of the PTS 3.3 C are its wide measuring range, high accuracy and high tolerance to unwanted external influences.The PTS 3.3 C allows the overall testing of meters and metering installations plus analysis of the local mains conditions.
Advantages
! Easy verification of meters under precise load conditions, using the built-in, compact, current and voltage source
! Automatic operation with (programmable) predefined load points without the need of an external PC
! Exchangeable Compact Flash (CF) memory card for storage of measurement results and customer data
! Display of vector diagram and phase sequence for analysis of the supply conditions
! User-friendly system for data input and easy operation of combined source and reference meter
! The system may be used either as a stand-alone reference standard meter, or together with the integrated power source as acomplete portable test system
Functions
! Independent generation of single or three-phase loading conditions for verification of meters
! Active, reactive and apparent energy measurement for single phase, three phase, 3 wire or 4-wire, systems with integrated error calculator and pulse output
! Vector diagram, harmonics spectrum, wave form and rotary field display for analysis of the mains conditions
! Burden measurement of Current Transformer (CT) and Potential Transformer (PT)

The portable, fully automatic PTS 400.3 PLUS is a modular three phase test system available in two versions. For many years, utilities have realized the importance of performing measurements and tests,onsite, at the metering installation. MTE continually supplies and develops new and improved products that reduces and simplifies the on-site efforts. The test system PTS 400.3 PLUS with enhanced functionality and high measurement accuracy does not only determine the accuracy of meters, but also provides additional information relating to the conditions at the respective mains points.

CALegration is an all-in-one software package to operate MTE´s portable and stationary test equipment product lines with the same software and on a common database.

It bundels the fuctionalities and advantages in a new comprehensive software solution.

The EMP 1.3 Quick Connection Device is used together with Electricity Meter Test Systems, and is especially recommended for situations where the time factor is of importance. It enables electricity meters to be mounted and connected rapidly for the purpose of their adjustment, test and verification.

The voltage presence indicator is a lamp drawing the attention of the operator to the presence of dangerous voltages.
The voltage presence indicator is a lamp drawing the attention of the operator to the presence of dangerous voltages – both single and three phase – on a meter test station installation. When the voltage
exceeds 50 VAC, the red warning lamp is illuminated intermittently.
