2 volt module needs to read 100.0 with 1.000 volts input
Posted: Sat May 07, 2011 11:55 pm
I have an EPM-8145B2V (2 volt 8145 digital panel meter).
I want it to read 100 (%) when a potentiometer delivers
10 volts to a resistor wired in series with the input.
How do I determine what (input) series resistor will
reduce the 10 volt input to an apparent 1 volt input?
(i.e., what is the input resistance of the module?)
How do I move the decimal point over 2 places to
the right so that 1.000 volts input will show as 100.0?
Thanks
