Issue:
Testing phase loss on a meter doesn't result in a null voltage reading.
Environmnet:
EasyLogic Series Power Meters
PowerLogic Series Power Meters
Resolution:
The voltage seen is what we call "phantom voltage", its a known phenomenon with all high impedance power meters. These phantom voltages are normal artifacts of the design and should not pose any safety concerns to the end user.
In some cases it'll probably disappear by power cycling the meter. Most power meters are not designed to monitor phase loss, as it'll always assume the presence of the 3 phases and the neutral, depending on your parameters setup. External devices are used to detect such occurrences, like phase control relays.
