The Model 4062 is a general-purpose instrument for conditioning, displaying, and monitoring one or two independent signals received from DC-to-DC LVDT's, potentiometer-type sensors, or other external two-wire DC voltage sources.

Each analog input may be either differential (floating) or grounded (single-ended), and may also represent output from some other instrument or instrument system.  Excitation of ±12 VDC is supplied for sources that require it.  For a wide-range instrument that can be dedicated to a single DC or AC voltage signal, see the Model 4060 DC/AC Voltage Instrument.

As with most standard 4000 Series models, both active low-pass filtering and user-selectable digital smoothing are provided (see Specifications), along with microprocessor-scaled ±10 VDC analog output for strip-chart recording, input to other systems, etc.

Functions Provided by the MODEL 4062 "STANDARD CONFIGURATION" (for a complete listing of the configuration, click here)

A preprogrammed tare function may be activated by front-panel button Via front-panel buttons, you can call to display either of the two "live" tared inputs; the maximum (most positive) value of either input since last reset; the minimum (least positive) value of either input since last reset; or the existing net difference between these maximum and minimum values for either input The "MAX" and "MIN" functions can be reset by a front-panel button For each input, each of three predefined limit zones of the tared reading ("HIGH," "OK," and "LOW") is tied to a specific nonlatching logic output The 4062's ±10 VDC analog output is not initially tied to any specific channel

There is a special version of the Model 4062 for true, on-line Statistical Process Control (see the Model 4K/SPC-62).

For typical dual-channel 4062 operations, see the following applications:

	Control of Carpet Shearing
	Monitoring Wheel Roundness

4000 Series options applying to the Model 4062 include

	RS485 (network) data communications
	DC-powered (vehicle) operation
