Photodiodes generate small photo-currents ranging from microamperes down to picoamperes, which cannot be measured with commonly available multimeters -amplifiers are required. Amplifiers such as the sglux dual channel MULTIBOARD converts very small currents into a voltage of 0 - 4V. Thus, such amplifiers convert the small current signal of photovoltaic elements (photodiodes) to signal voltages suitable for typical voltmeters, microcontrollers and PLC systems.
