4.6. Measuring the output voltage or output current
In some cases it may be necessary to measure the output current or output voltage.
Attention!
This measurement must be made by qualified professionals only. Having completed the measurement
take utmost care in re-assembling the controller because otherwise the operating permit will become void!
Notice
The measuring device must be designed for true root mean square measurement (true RMS). Other
measuring devices would show random values.
The output voltage can only be measured with the vibrating drive connected! The load connector must be
plugged in because otherwise the measurement may perhaps be made in the wrong operating mode.
The use of the measuring adapter ESZ-02 (see chapter 1.6) greatly facilitates measurement of the output voltage and
current. The measuring adapter is fitted with appropriate connectors for easy connection between controller and vibrat-
ing drive. The use of moving-iron measuring instruments makes sure that the true root mean square value is meas-
ured.
