During initial calibration or periodic inspection of the
SmarTach
®
, you must carry out the steps in the exact
order in which they are described below!◄
Important
Step 1 Programming the installation data
• Confirm or change (where necessary) the legal
parameters.
• Confirm or change (where necessary) the non-legal
parameters, e. g. device-specific and vehicle-specific
parameters.
See Chapter 10 "Tachograph programming" on Page 56.
Remark:
The legal parameters are first saved in the test device. The
non-legal parameters are immediately transferred as
individual values (programmed).
Step 2 Determination of the characteristic coefficient imp/km
(W value):
Measuring on the road or on the rolling road.
Remark:
The determined values are first saved in the test device.
Step 3 Calibration of the SmarTach
®
using the key:
The CTC II carries out the following steps:
• Adjustment of the K value
• Transfer (programming) of the legal parameters
• Pairing with the KITAS (updating of the KITAS data); see
Chapter 9 "Activating KITAS" on Page 55.
Remark:
Calibration lasts around 150 seconds.
