When measuring the output voltage, make sure that you are measuring AC voltage between the COM terminal and any station that you have turned on. If you happen to turn your multimeter to DC voltage, the reading will be about 0 (because the average DC reading of an AC wave is 0). Also check to make sure the terminal blocks are inserted tightly.
