The CCM-S indicates the relative elongation compared to the nominal length of a stored standard chain according to
ISO606. The measurement results of the CCM-S are a combination of measured and calculated values.
4.1 Construction and function
4.1.1 Factors influencing measurement
_
The CCM-S detects the chain within the defined chain speeds (see chapter Technical data).
_
Changing load directions and chain speeds have only a minor effect on the functionality and results of the
CCM-S.
_
Any change to the chain tension force which causes stretch under load and hence a change in the length
affects the measurements. Under normal circumstances, however, this effect lies in the region <0.25 %
elongation (at a load of ~15 % of the yield strength of the chain). The same applies to temperature, i.e. the
CCM system outputs an elongation value made up of wear, stretch under load and thermal stretch.
_
Longitudinal vibrations do not present a problem in respect of measurement with the CCM system, as these
represent a relative change in speed.
_
Because the dimensions (particularly the nominal pitch) of different chain sizes vary, the correct size CCM
model must be used for each chain size!
_
Chains that have different nominal pitches within a single chain are not compatible with the CCM system!
_
The CCM system provides averaged elongation values and is thus not capable of detecting and identifying
sudden changes of length even up to the point at which the chain fails!
