When there is a suspected problem with a mass flow controller, it is necessary to check the power source, display unit, settings unit, cables, and SEC itself for malfunctions, in order to determine
the cause of the problem. The MFT-20 can drive the SEC and monitor its input and output voltage, while carrying out the necessary control functions to determine if the SEC is operating properly. This allows the user to determine if the source of a problem is the SEC itself or the power source, before detaching the SEC from the equipment piping. An internal potentiometer enables control of the SEC as well.
