Assume Vsig, the signal voltage, is a glass pH-sensing electrode with R1 representing the resistance of the glass membrane across which the pH dependent potential develops. Such a membrane would have an internal resistance of about 1000 megohms. Assume that the pH meter is connected directly to the pH electrode and that R1 is its internal resistance. Draw an electrical diagram showing how your circuit would look under these conditions. Then determine how large Rin, the input resistance, would have to be to have Vmeter (the voltage read by the pH meter) report Vsig to within at least 90% of its true value.
