5.5 Auto Zero Maintenance (AZM)
The Dyna-Link 2 employs an auto zeroing maintenance mechanism to adjust the zero
reading to the center-of-zero (COZ). COZ is defined as the tension reading is within
¼’d’ of zero. AZM continuously adjusts zero to maintain COZ. It is recommended
that AZM is on to maintain the highest accuracy. However, there are circumstances
when it should be turned off. This can happen when minor variations of tension occur
while picking up Dyna-Link attachments and the variations fall within the AZM
capture window. The AZM capture window (usually 1 ‘d’) and capture time (usually
eight seconds) can be adjusted by MSI to meet custom requirements.
