SensorMeasurement Input
STG-Mode
Application
 Measurement with strain gages
(full / half / quarter bridges)
 Measurement with sensors which
provide a fixed ground (GND) reference
(with no definite ground reference the
input may drift, because of the high
impedance of the signal input)
Features
 Bridge connection supporting 2-wire,
4-wire and also 6-wire technique
 Bridge completion using internal resistors
 Shunt check in configuration mode as well as in measurement mode
Adjustable shunt resistor 5 kΩ to 500 kΩ (minimum and maximum value depends on
the current setting of the excitation voltage), connectable to each bridge section (quadrant).
The complete adjust data can be output to the software (CSV format) and can be loaded and applied to the
sensor for verification of stability and repeatability.
 Sensor break detection for all 6 wires (IN [up to an input range of 200 mV], VOUT, SENS)

Common Mode Rejection Ratio (CMRR)
To guarantee a correct measurement of the input signal over the complete measurement range (uncropped
signal amplitude), the input voltage on IN+ resp. IN- relating to the GND potential should not exceed 4 V.
Sensor excitation
 selectable bipolar voltage ±0.50 / ±1.25 / ±2.50 / ±5.00 V
 current load up to 45 mA per channel
