FNIRSI® SG-002 Signal Generator & Calibrator 4-20mA 0-10V
The FNIRSI® SG-002 Signal Generator & Calibrator is a compact handheld source designed for working with standard industrial analog control signals. It provides an adjustable voltage or current output that can be connected to controllers, indicators, transmitters, and automation equipment during setup or maintenance. Its front digital display gives a clear numerical reading while the rotary encoder allows direct, controlled signal adjustment.
The instrument is especially useful when a technician needs to simulate a sensor or process signal without operating the complete system. By generating common ranges such as 0–12V and 0–24mA, it helps users observe how connected equipment reacts across its operating span. Voltage and current modes are selected from the front panel, while configurable display and adjustment settings support convenient bench or field operation.
The SG-002 accepts external DC power, micro-USB power, or an optional internal rechargeable battery, providing flexibility for workshops, laboratories, control panels, and on-site servicing. Its compact enclosure, removable terminal connection, stored output setting, and selectable coarse or fine adjustment make it suitable for repeatable testing tasks. It offers a practical way to check signal paths, verify scaling, calibrate analog inputs, and support troubleshooting in industrial electronic and automation systems during regular technical service work.
