    The flame sensing is in

    microamps and should be between 2 to 10 microamps, 3 to 5 is normal on most applications. Check the specifications on the electronic control your system uses.



    You are correct to place the meter in series with the sense terminal on the electronic control or on some controls burner ground is also an acceptable location. If your meter has a microamp setting it would look like this
