MTS-50 Meter Test System

Phase: 3

AC voltage output: 0-792V

AC current output: 0-60A

Accuracy: 0.05%RG (Class 0.05) or 0.1% RG (Class 0.1)

This Meter Test System features state-of-art designing with high accuracy. It is composed of high accurate (class 0.05% or 0.1%) standard reference meter and power source (up to 50A). This system is particularly designed with modular structure for calibration and test of different single phase/3 phase electronic/inductive active and reactive energy meters.

It is operated under high functionality with user friendly interface.

Main function:

1. Calibrate all kind of single/three phase electronic/inductive active and reactive energy meter
2. Automatically or single-step manually test basic error, creeping, starting, standard deviation of single/three phase energy meter, save user-defined calibrating scheme in Auto calibration
3. Support variables influence tests, such as: Voltage, frequency, harmonics, reverse phase sequence, Voltage unbalance, etc
4. Support special tests in energy meter type test, such as: phase triggering, pulse train triggering, etc
5. Support DLT-645 communication protocol，multi-testing of  multifunction meter such as: demand indication error, demand cycle error, time slot switching error, energy error of different tariff period, etc.
6. With OCXO, daily error of energy meter can be detected
7. Output 2nd ~63rd harmonics

Main features:

1. 8” color touch screen, interface friendly, easy to operate;
2. Equipped with RS232, Ethernet, and WiFi interface, MTS-50 can either support stand-alone operation, PC control or handy wireless terminal control;
3. Communicate with tested meters thru RS-485;
4. Automatically calculate the error of meter, and the related data can be downloaded thru U-disk;
5. Self-protection, alarming and displaying overload location for equipment output overload, Voltage short-circuit, Current open-circuit;
6. Automatically detect, diagnose and alarm for failure.
7. Remotely updating online, easily achieve software updating;
8. Support calibration by user locally
