Fields of application
K3607 A0833-3.1 HBM: public 7
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.

Connections

4 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 pro
vided 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.

Calibrating the measurement chain
K3607 A0833-3.1 HBM: public 9
5 Calibrating the measurement chain
SConnect the calibration instrument to the measurement chain you wish to
calibrate in place of the 350‐SG transducer. If there is an extension cable
on the measuring amplifier, leave it in place in order to capture the ohmic
and capacitive cable effects.
SUse S1 to preselect the desired polarity of the measurement signal.
SSet S2 (calibration step switch) to zero.
SIf necessary switch the measuring amplifier to full bridge (K 3607 operates
as a full bridge).
SBalance the measuring amplifier and subsequent instruments to zero in
accordance with their operating manuals and if necessary carry out capaci
tance adjustment.
SUse the calibration value switch S3 and the calibration step switch S2 to set
the desired calibration signal:
S
SSet the measuring amplifier to the desired output signal in accordance with
its operating manual. In principle the measuring amplifier should be cali
brated in the measuring range you intend to use for measurement. If the
measuring range of the amplifier is changed, the switching error needs to
be taken into consideration.
1) *Effect of the calibration step switch (S2):
2) The grading error for the percentage steps as set out in the specifications will be maintained for
every step if the internal resistance Ri of the bridge excitation source plus cable is v1. For an
internal resistance Ri v4the error in the calibration steps is kept at between 0 and 50 %.
For a six‐wire circuit the tolerances are maintained if the excitation voltage to the K 3607 is
readjusted precisely enough.

Works calibration of the K3607
10 A0833-3.1 HBM: public K3607
6 Works calibration of the K3607
The K 3607 is calibrated in the factory under the following conditions:
- Ambient temperature: + 23 oC
- Connector cable:
- KAB0238A-3 (included in the list of components supplied), cable length
= 3 meters
- Cross‐section of each bridge excitation wire 1.5mm2
- Internal excitation voltage resistance: v1

Effect of cable resistance
K3607 A0833-3.1 HBM: public 11
7 Effect of cable resistance
The cable effect for KAB0238A‐3 cable is calibrated in at the factory. This
applies to four‐ and six‐wire circuit at the end of the 3‐meter long cable.
On subsequent connection in four‐wire circuit, the output signal is reduced by
the K factor due to the resistance of the excitation wires.
The K factor is calcultated as follows:
Bridge resistance)
The resistance value of an excitation wire is used for the r term. In the case of
KAB0238A‐3 cable this resistance r = 0.0118 . According to the formula (1)
this gives a value of 0.99993 for the K factor. This means an absolute calibra
tion error of 0.007% if KAB0238A‐3 is not used.
A switching step error also occurs. Depending on the position of switch S2 the
internal resistance of the K 3607 alters slightly, as does the effective excitation
voltage due to the cable resistance r.
The grading error of the percentage steps increases by some 0.02% at 10 of
cable conductor resistance.
When connecting a six‐wire circuit the cable effect is corrected and the K factor
= 1. No additional grading error occurs (internal excitation voltage resistance <
1 ).
If KAB0238A‐3 cable is not used, an absolute calibration error of the corre
sponding size occurs. This means the output signal is increased by a factor of
K = 1.00007.
