I recently purchased a DROK 0.40 2.5-30V LED voltmeter. In a couple of internet searches, some posters speak of an adjustable potentiometer, presumably for calibrating the the voltage readings. Is there a potentiometer on this device, and if so, how do you get to it and adjust the device ?

Thanks

Hello Rob,
Thank you for writing in.
