GENERAL PURPOSE SIGNAL CONDITIONING INSTRUMENTATION
Encore offers a line of General Purpose Signal Conditioning instrumentation
packaged as interchangeable two-channel plug-in modules. Encore's broad product line includes frequency to
voltage converters, strain gage amplifiers, accelerometer conditioners,
digital voltmeters, and DC power supplies. A common CAL input on the
rear of the rack is applied to all modules to allow calibration of
the entire rack. Calibration function depends on the GPSC modules installed; the
Model 633 will apply a shunt calibration resistor across the bridge;
the Model 149 will apply a reference charge source to the input.
