Solution
Power supply is not properly sized. Check power supply voltage and
current rating.
Polarity is not properly matched. Check and correct wiring polarity.
Sensor model may be improperly sized for application. Determine the
normal operating voltage of your monitored circuit and ensure sensor
selected is equal to or slightly higher than the normal operating voltage.
Monitored load is not AC or is not on. Check that the monitored load is
AC and that it is actually on.
