The microcomputer controlled Model 1080 FlexiTESTER® can simultaneously measure unknown DC signals within a millivolt, voltage or current range, and generate these signals to test and calibrate process instrumentation . Independent dual displays permit the input and output signals to be displayed at the same time without switching. The output display indicates the signal actually present at the output terminals. The low voltage, calculator-type fluorescent displays are hooded for high visibility in either dim or bright light, and operate even in very low temperatures. FIexiTESTER is designed for a high degree of versatility in both field and laboratory test applications ; it can even service instruments still installed in a process loop . Each of the signal ranges has a separate set of input and output terminals on the front panel . These separate terminals and controls permit the user to connect a number of devices to the 1080 simultaneously.
