3.3. Calibration Procedure
3.3.1. General Procedure
For calibration in the system environment, the application kit from Micronas is recom-
mended. It contains the hardware for generation of the serial telegram for programming
(Programmer Board Version 5.1) and the corresponding software (PC83x) for the input
of the register values.
For the individual calibration of each sensor in the customer application, a two point
adjustment is recommended. The calibration shall be done as follows:
Step 1: Input of the registers which are not required to be adjusted individually
The magnetic circuit, the magnetic material with its temperature characteristics, the filter
frequency, the output mode and the GP Register value are given for this application.
Therefore, the values of the following registers should be identical for all sensors of the
customer application.
– FILTER
(according to the maximum signal frequency)
– RANGE
(according to the maximum magnetic field at the sensor position)
– OUTPUTMODE
– TC, TCSQ and TC-RANGE
(depends on the material of the magnet and the other temperature dependencies of
the application)
– GP
(if the customer wants to store own production information. It is not necessary to
change this register)
As the clamping levels are given. They have an influence on the D/A-Readout value
and have to be set therefore after the adjustment process.
Write the appropriate settings into the HAC 830 registers.
