    Hi, I am looking to get the 1.9999mA meter (link to Amazon page below). I am curious as to what the operating voltage tolerance is? At the top of the Amazon page it states +/- 5% (which is +/- 0.25V). But the Drok page and lower down it states +/- 0.5V.

    I have a 5 volt regulator that has an actual output 5.35V and I’m hoping this will work to power the meter.

    Hello Spencer Sutton，
    Thank you for writing in.
    The operating voltage of this meter is DC 4.5V-5.5V.
    It is recommended that the power supply of the meter is stable DC 5V power supply.
    Is the output of your 5V regulator stable 5.35V?
    If not, it is not suggested that you you apply this regulator as the power supply of the meter because if the output voltage of the regulator is higher than 5.5V, the meter will be burnt.
    Hope this can help you.
    Best regards
