The Model 3760 is a single
-
channel panel instrument for DC Voltage and 4-20mA sensors;
intended for applications involving single ended or differential DC Voltage signals with
ratings between 50 mV to 200.0 Vdc input full scale or 4-20mA inputs. The 3760 will
supply excitation, conditioning and provide a calibrated Engineering Unit's display and
analog output signals for the measurement of pressure, displacement, speed, load and other
parameters associated with DC based sensors. The 3760 is front panel configurable with
user selectable wide gain, zero, symmetry, and selectable analog output of voltage and
current signals. Display is user configured and independently adjustable for engineering unit
scaling up to ± 199950 independent of the analog full scale signal.
The Model 3760 can be calibrated by the “two-point (dead-weight)” process involving
known “zero” and “full scale” input parameters. A convenient “RCAL” front panel push
button or rear panel connection is available for calibration verification.
