Measurement
A simple way to manually measure load regulation is to connect three parallel load resistors to the power supply where two of the resistors, R2 and R3, are connected through switches while the other resistor, R1 is connected directly. The values of the resistors are selected such that R1 gives the minimum load resistance, R1||R2 gives the nominal load resistance and either R1||R2||R3 or R2||R3 gives the full load resistance. A voltmeter is then connected in parallel to the resistors and the measured values of voltage for each load state can be used to calculate the load regulation as given in the equation above.
Programmable loads are typically used to automate the measurement of load regulation.

Famous quotes containing the word measurement:
“That’s the great danger of sectarian opinions, they always accept the formulas of past events as useful for the measurement of future events and they never are, if you have high standards of accuracy.”
—John Dos Passos (1896–1970)
