STATIONARY
MTE Meter Test Equipment for testing single and three-phase, standardized and individual test systems are covering all legal metrological test requirements for simple meters, high precision multifunction meters, smart meters, and reference standards. Flexible and modular system components for the optimal customer orientated solution.
METER TEST SYSTEM
MTE`s universal meter test systems cover all state-of-the-art test requirements for modern single- and three-phase meters following IEC- and ANSI-standard. They automatically perform the meter calibration and verification procedures for meters with or without test link.
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. Test systems are available with fixed meter racks or with moveable trolleys and gantries to fulfill different requirements and increased test capacity.
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.
REFERENCE STANDARD
The electronic system reference standards in 0.05 or 0.02 accuracy class are precision measurement units for all AC values, which are used in the measurement of energy. The wide measurement range and the high precision are the main characteristics of the reference standards.
POWER SOURCES
Single-or three-phase computer controlled voltage and current sources (up to 4000 VA per Phase), are designed for use in meter test systems and laboratories. The output values are stabilized by an internal feedback loop and an overlaid digital control loop for amplitude, phase angle and distortion factor.
The SQE 120.3 is especially appropriate for test laboratories to perform compliance, acceptance or type test of electricity meters and different types of power, energy and power quality measurement devices, following the existing (IEC 61000-4-30, EN 50160) and the new (IEC 62586-1,2) power quality standards.
TESTING OF CLOSED LINKS
With ever increasing frequency, meter manufacturers and meter operators are producing and using meters that do not allow the links between the current and voltage measuring circuits (I-P links) to be opened for test or calibration purposes.
SOFTWARE
ACCESSORIES
In many meter test stations, separation of energized parts and user cannot be realized by means of stationary separating safety equipment. For this reason, movable or non-separating safety equipment is used. To allow the use of safety switches or light curtains in meter testing stations, a safety related signal evaluation is required. Here a safety relay analyzes the starting conditions and in case of need interrupts the dangerous voltage.

PORTABLE
Portable MTE Meter Test Equipment for testing single and three-phase devices over the complete range of accuracy classes used for on-site testing or in laboratories. Light in weight and with user-friendly keyboard layouts and menu-driven software, the devices are easy to operate and your solid partner for on-site testing of different kind of meters.
TEST SYSTEM
Comprehensive portfolio of single- and three-phase meter test systems in accuracy class 0.2 up to 0.05 with current or current and voltage sources in different versions.
REFERENCE STANDARD
Comprehensive, innovative range of reference standards, single or three phase, available in accuracy class 0.2 up to 0.01. Ideal devices for the overall investigation for testing electricity meters and their installation on site.
POWER SOURCES
A wide range of three phase current or current and voltage sources allow testing over the complete load range.
The CheckSource 2.3 is a three-phase current source for currents up to 6 A. The test currents are generated with the same frequency and a user-defined phase shift to the voltages applied to the voltage inputs (phantom load). Alternatively the test currents can also be generated with a user defined frequency.
The PPS 400.3 is a powerful and portable threephase current and voltage source. All test values are generated absolutely synthetically with a high degree of accuracy and stability. Following the different demands of customers, this source is available in two versions, for the supply of transformer meters with a maximum current up to 12 A as well as wider range source up to 120 A. The PPS 400.3 portable power source may be used.
