5.2 Setting options of the measuring amplifier
The measuring amplifier must be adapted to the (displacement) sensor used.
The following parameters must be set:
•
Position of the electrical zero point,
•
Phase compensation (possibly caused by the sensor type and the
connecting cable),
•
Gain (compensation of sensor sensitivity).
At the factory, a
basic configuration
for all three parameters is set in the
measuring amplifier. This is achieved by using a variable component assembly
(resistors / capacitors) based on:
•
a reference displacement sensor, if the sensor type is known,
•
the sensor specification provided by the customer,
