First calibration 10.2 Calibration instructions
Edition 07/2007 Technical Description DTCO 1381 10 - 7
TD00.1381.00 132 102
10.2.3 Programming the UTC time
Before activating the DTCO 1381 as the EU control device, unre-
stricted programming of the UTC time is possible.
After activation of the DTCO 1381 and one-off programming of the
UTC time, this function is blocked for security reasons. The
workshop card must then be removed and re-inserted; i.e, the
workshop card must be re-authenticated.
10.2.4 Parameter measurements
Before the parameter measurements – in particular the character-
istic coefficient (w-value) – the following must be checked:
1. Check whether all cables – in particular the KITAS sensor cable –
are undamaged.
2. Check whether the KITAS sensor cable is connected directly, i.e.
without branchings, at DTCO 1381 and KITAS 2171.
After the parameter measurements and programming – in par-
ticular the characteristic coefficient (w-value) – the following must
be checked:
3. Check whether the DTCO 1381 displayed or saved any sensor
faults.
4. Check whether the programmed and saved parameters are
according to the beforehand measured parameters.
Please refer to the testing device instructions for information on
how to prepare for and execute the parameter measurements.
If one of the above-mentioned points is not fulfilled, locate the
cause and repeat the measurement.
