      I have my Vue setup on my 240V mains (120V per phase). I am confused whether I should set the multiplier to 1 or 2 for an an accurate reading of my mains. I assume the vue senses if a load is one one CT (phase) or the other and calculates accordingly?

      Hello @mnrad,

      There is no need to put a multiplier in for your main sensors. This feature was added so customers could adjust their voltage assumption to something other than 120v per phase.

      Please let us know if you have any further questions.

      What about when setting up the circuits and its a 240 stove what does the multiplier have to

      Yes, if you have a dual pole circuit, you put one 50A sensor on one of the legs and then set multiplier to 2 in the app to correctly measure the watts used by the stove.

      One thing I have learned over the years it was is simple to me can be hard for others to understand.  I have a EE degree so these multiplier calculations seem simple.  I also have many more things that are hard for me to understand than are simple.    I think a web calculator where the circuit voltage is entered and the multiplier is provided would be helpful.


      Technology frightens me to death. It’s designed by engineers for other engineers. And they always come with instruction booklets that are written by engineers for other engineers – which is why almost no technology ever works.

      Can you give an example of the multiplier function.

      If my legs measures 137vac .

      Do I devide 137/120= 1.14

      Hi @jcueva You are correct the multiplier if yu voltage is 137vac, would be 1.14.

      So what if the voltage going to the Gen 2 was 220, but the 200 amp CV was sat on a 240 supply,  can I use the multiplier to correct the calculation ?  What exactly is the formula?

    • #8597 Report Abuse

      In this situation, your multiplier is 2.0, since your nominal single side of each circuit voltage is 110, so the nominal voltage across the two different phases is 220v.  I hope this helps a little.
