K3607

K3607 - Calibration Unit

The K3607 calibration unit can be used to calibrate measuring amplifiers or measuring chains without introducing a mechanical quantity into the measuring chain.

To this end, the calibration instrument is equipped with a high-precision resistive network in a star configuration that is designed to simulate full-bridge 350 Ω sensors. The extremely low intrinsic capacitance and self-inductance of the built-in precision resistors places the calibration instrument in the 0.025 accuracy class. With the use of a suitable measurement amplifier, the K3607 calibration instrument can be operated in a six-wire circuit to balance the ohmic and capacitive effects of long measurement cables.
