This is good for price and appearance. However, quality wise bit problem. This display is accurate for higher voltage values but not accurate for lower voltage values. I want to use this with my own DIY power supply. Cannot adjust for whole range for accuracy.

radiospmr same issue common with all instruments trying to measure voltage, current and power measurements. you can offset this by trying to measure voltage and current at the output port sharing the same ground location. location of probe points can becrucial in determining accuracy. therefore lab grade instrumentation for precise measurement is expensive and out of reach of most.

so you must accept slight inaccuracies in affordable instruments.

radiospmr voltage varies all along the cable, it is influenced by the location of probe points along the cable. try using ISOLATED power supply to power this device, this minor inaccuracy and offset problem should be solved.
