Apply input signals as needed according to the actual hardware and
the application configuration.
1. Inject a symmetrical three-phase voltage and current at rated value.
2. Compare the injected value with the measured values.
The voltage and current phasor menu in the local HMI is located under Main
menu/Measurements.
3. Compare the frequency reading with the set frequency and the direction of the
power.
The frequency and active power are located under Main menu/Monitoring/I/O
status/Monitoring/PWRMMXU(PQf):1. Then navigate to the bottom of the
list to find the frequency.
4. Inject an asymmetrical three-phase voltage and current, to verify that phases are
correctly connected.
If some setting deviates, check the analog input settings under
Main menu/Configuration/Analog inputs
Measured values such as current (phase and residual) and voltages (phase-to-earth,
phase-to-phase and residual) as well as active, reactive and apparent power, power
factor phase angles as well as positive and negative sequence currents and voltages are
available in the local HMI under Main menu/Monitoring/I/O status/Monitoring.
Navigate to the measurement function that contains the quantity to be checked.

Also the Signal Monitoring tool in PCM600 can be used to read the measured values.
In many cases it is more convenient to use PCM600 since, for example, reports on
measured values can be exported from the Signal Monitoring tool to other tools (for
example, MS Excel) for further analysis.
