United StatesWhat does PULSE only Mean
I had 2 of these units installed to measure KW usage for shared radon fans in 4 condo units. The radon fans are 110V. After 3 months, the KW usage has not changed. Showing 0.5, same as initial install for both KW meters. They were installed by a licensed electrician. Only the PULSE light is on, not the POWER light. What does PULSE only mean? According the annual KW usage, the monthly usage rate should be showing approx 40 KW per month. Not sure these are working.
