Wayne62 after some trial and error... the button to the left of the screen is screen on and off with a single click, when screen is flashing its down-decrease the displayed voltage value. the button to the right with a single click will illuminate an LED indicating input(positioned on the left) or output (positioned on the right) voltage with the display showing that corresponding value. long press of the right switch will enter data input mode. single click of the right button to display the value you wish to adjust, long press and the screen will flash indicating data input mode. Using your multi meter, check the input voltage and adjust the displayed input voltage to what you read on your multi meter. switch to view the output voltage, use your multimeter again but on the output terminal, with a small flat screw driver adjust the multi turn potentiometer to correspond with the value displayed on your multi meter. then only with single clicks of the left-down and right-up buttons, correct the displayed voltage on your module. Don't Long press the right button unless you wish to exit the data input mode. and long press of the left will switch off the display. might take a few adjustments to equalize the module display with the multi meter reading on the output. hope this helps.
