and legally required parameters
Enter vehicle registration number
Enter registering member state
Pair DTCO 1381 and KITAS 2171 "manually"
Check and demonstrate the proper functioning of the EC
recording equipment
Measure display errors
Test and demonstrate that the entire system complies with the
permissible error limits concerning distance and speed, defined
by CR (EEC) 3821/85, annex I B
Check approval mark of the DTCO 1381
Check sealing
Check tire size and effective wheel circumference
Check existing installation plate; create a new installation plate
and seal it if necessary
Note the legal provisions applicable in your country and check, how
the first calibration must be performed and whether further tests of
the EC recording equipment are prescribed within the first cali-
bration.
It is possible to access the calibration functions through the cali-
