 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.).
The
4060's single DC or AC analog input may be either differential (floating)
or grounded (single-ended), and is galvanically isolated to yield
an operating common-mode range of 1500 V. For an instrument that can
be dedicated to one or two DC voltage signals (only), see the Model
4062 DC 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.

MODEL 4060
"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 the
"live" tared input; the maximum (most
positive) value of that input since last reset; the minimum
(least positive) value of that input since last reset; or the
existing net difference between these maximum and minimum
values |
|
The
"MAX" and "MIN" functions can be reset by a front-panel
button |
|
Each of the standard
seven predefined limit
zones of the tared input reading is tied to a specific nonlatching logic output |
|
The
4060's ±10
VDC analog output derives from the
tared analog input, and is initially scaled for 1 mV of output per 1
mV of input |
|
There
is a special version of the Model 4060 for true, on-line
Statistical Process Control (see the Model
4K/SPC-60).

typical 4060 operations, see the following applications:
