I need help please. I cannot do mathmatics and need help working out the resistor values for the voltage divider chain on a LM3914N operating in a suppressed zero mode. I am trying to put together a portable, simple read-out meter for testing solar battery installations. I have based my design on this circuit
Is there anywhere a spreadsheet or a program for working out the values for me. Or I can pay somebody to do the calculations for me. Can anybody help please, I am stuck. Mark
