    How do I adjust the output voltage back down?  It is staying at maximum even though I press the left button.

    Hello Barry Klein,

    According to your descritpion, it should be this item, #180079, https://www.amazon.com/dp/B07LC4LNTD?ref=myi_title_dp

    Could you please tell us how large the input voltage is? How about the right button?

    Best regards,

    DROK

    I don’t have it hooked up any longer but can try it again.  My input was an adjustable bench supply, capable of >12VDC.

    It was staying set at the set voltage between power ups ok, but it would just not adjust down.  Perhaps bad left switch then?

    Hello,

    Is it 12v input in that case? If both button can’t work, would you please try to calibrate voltage reading?

    You can find calibration method from instruction or refer to below steps.

    1. Hold the left button and connect power supply, then release button, screen will start flasing

    2. Check the actual output voltage with multimeter. Then adjust voltage reading with left or right button unitl it is the same as multimeter reading. Calibration data will be saved automatically after 2 seconds.

    3. Power off and power again, calibration is finished. Error can be ±0.01V. If error is larger, you can calibrate again.

    If it still not work, would you like to show us your operation so that we can check further?

    Best regards.
