impedance impossible
Posted: Tue Oct 30, 2012 4:31 pm
Hi I need to read the voltage from a power supply, the datasheet for the power supply states that any digital measuring device needs an input impedance of at least 10M, unfortunately the Digital measuring device I have states that the maximum input impedance is 1M Ohm. What options do I have? Is there a circuit that can increase the input impedance of my measuring device?
