K3607 Calibration Unit

K3607 Calibration Unit

The K3607 calibration unit can be used to calibrate measuring amplifiers or measurement chains without imposing a mechanical quantity on the strain gauge 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-ohm strain gauge 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 K3607 calibration instrument can be operated in six-wire circuit for balancing the ohmic and capacitive effects of long measurement cables.
