Fields of application

The K 3607 calibration instrument can be used to calibrate measuring
amplifiers 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-Ω 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.

Connections

The connector cable between the calibration instrument and the measuring
amplifier is connected either to the 7-pin Amphenol connector MS 3102
A16S-1P (St1) or to the 5-pin S3 (Bu 1 . . . Bu 5).
The contact assignment is shown in Fig. 6.1. The Amphenol connection is
provided for a six-wire circuit. If the intention is to connect a six-wire circuit to
the pin terminals, connections C and F on the measuring amplifier must both
be connected to Bu3 on the calibration instrument, and connections B and G
must both be connected to Bu2.
