Test Performance, Result Display and Evaluation

METES systems have a manual and an automatic mode for carrying out manual and automatic tests on all single and three-phase electronic and Ferraris electricity meters.

All the quantities available in the system can be displayed online both during and independently of tests. The measured quantities can either be displayed numerically or in the form of graphical displays, such as vector diagrams or bar graphs, in one or more display windows. Using the vector diagram to examine the voltages and currents makes it possible to check the correct connection of a meter or the connection of current and voltage transducers, for example.

The reaction of the test object is evaluated during the course of the test. An indication is given for each test point as to whether or not the result lies within the configured tolerance range. The measured error is displayed directly in numerical or graphical form (error curve).

After a test, all the results are displayed clearly in a table. Each line of the table contains the information on an individual test point.
