The FNIRSI SG-003A multi-functional Signal Generator a.k.a. Process Meter/Calibrator is a high-precision voltage/current generator and meter. The SG-003A provides highly accurate reference voltages or currents for testing and calibrating other measurement instruments like multimeters and oscilloscopes.
Besides voltages and currents, the SG-003A also generates rectangular pulse signals with precisely programmable frequencies and duty cycles. Its converter mode turns the SG-003A into a precision voltage-controlled current source, or current-controlled voltage source, and even a voltage- or current-controlled frequency generator.
The SG-003A is a great tool for checking your multimeter’s accuracy and precision, and for testing e.g. LEDs.
