3 Fields of application
The K 3607 calibration instrument can be used to calibrate measuring ampli­
fiers or measurement chains without imposing a mechanical quantity on the
SG transducers belonging to the measurement chain.
For this purpose the calibration instrument is equipped with a high‐precision
resistance network in star configuration, designed to simulate 350‐

SG
full‐bridge transducers.
The extremely low self‐capacitance and self‐inductance of the inbuilt precision
resistors place the calibration instrument in accuracy class 0.025.
When an appropriate measuring amplifier is used, the calibration instrument
can be operated in six‐wire circuit for balancing the ohmic and capacitive
effects of long measurement cables.
