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 120A). 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.

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-100 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.
