  15. if**ro

    The product arrived on time and well packaged ! Very good ! The DUALR3 and the android app are easy to set up. I have tested the meter function and the two channels works well togheter. It has a small delay to display the values of: voltage, current and powers. Sometimes, i have to refreesh de app window to update the values. The functions of load control and meter works separately. You must choose only one function at a time. I liked this set.
