Based on the "Standard Input" Model 4030, 4032, 4060, 4062, or 4077, each "4K/SPC" instrument provides true, on-line SPC in either bit-controlled operation (for discrete parts) or time-controlled operation (for continuous processes). 

This is "true" SPC because it ensures a stable process not just within fixed "spec-determined" setpoints, but also within natural control limits continuously calculated from the process spread, using "±3-sigma" conventions.

The single-channel Model 4060 is a wide-range, general-purpose instrument for conditioning, displaying, and monitoring the signal received from an external two-wire DC or AC voltage source.  The input signal may also represent output from some other instrument or instrument system.  Excitation of ±15 VDC is supplied for sources that require it (DC-to-DC LVDT's, potentiometer-type sensors, etc.).
