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

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:
