    in reply to: 4-20 mA to 0-5 vdc conversion board #35177

    Hello Philip Correll，

    Thanks for writing in. Is it 200327?

    To check it carefully, would you please kindly take some images to show the whole operation?  And which jumper pins did you connect?

    Regarding to zero and span potentiometers, the operation is as follown:

    1.When the current input is at minimum (0mA or 4mA), adjust the Zero potentiometer to make the voltage output to be the minimum value (0.0V or others).
    2. When the current input is at maximum (20mA), adjust the Span potentiometer to make the voltage output to be the maximum value (3.3V or 5V or 10V; the output can be as low as 2.5V when the current input is within 4 -20mA).

    Best regards.

    in reply to: Monitor 200139 wiring #35155

    Hello Robert,
    Thanks for writing in.
    If the part connected to L+ and L- is the load you need to measure, the wiring is no problem.
    Regarding to the bottom connection, it seems it is not the part of meter’s wiring. We are not sure if it has any relation to the meter.
    Best regards.
