Example
Channel 1 is to be calibrated with four-wire connection at two points with 100 Ω and 350 Ω. The vendor
offset for the 2-wire calibration is -2607 (taken from index 0x800F:03).
The following measured values are recorded:
100 Ω through precision resistor
X
1
= 25600 (1/256 Ω)
171125, read in index 0x800E:01
Y
1
= 171125
350 Ω through precision resistor
X
2
= 89600 (1/256 Ω)
592224, read in index 0x800E:01
Y
2
= 592224
With the equations (1) - (3):
the resulting values for g
f
, G
U
and O
U
are:
The indices accept only integer values. The following entries are to be made in the CoE:
Index 0x8000:17 = -12
Index 0x8000:18 = 9960
Subsequently the vendor calibration is to be deactivated (0x8000:0B) and the user calibration activated
(0x8000:0A).
